&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger.&lt;br /&gt;
&lt;br /&gt;
In Monachello's study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes &amp;lt;ref name=&amp;quot;ref3&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2- into the vacuole (negative current), when cytosolic  [NO3 2-] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa &amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. &lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis&amp;lt;ref name=&amp;quot;ref4&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition&amp;lt;ref name=&amp;quot;ref6&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
== Expression ==&lt;br /&gt;
&lt;br /&gt;
The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested &amp;lt;ref name=&amp;quot;ref5&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast&amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;.&lt;br /&gt;

[[File:08.jpg|200px|thumb|right|Phylogeny of predicted AtCLC proteins.]]&lt;br /&gt;
The AtCLC proteins were predicted to consist of 9–11 transmembrane spanning domains and two conserved CBS domains at the carboxyl end. These domains were similar in sizes and positions to those of CLC-0 and mammalian CLCs.&amp;lt;ref name=&amp;quot;ref2&amp;quot; /&amp;gt;.&lt;br /&gt;

AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger.&lt;br /&gt;

In Monachello's study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes &amp;lt;ref name=&amp;quot;ref3&amp;quot; /&amp;gt;.&lt;br /&gt;

The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. &lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis&amp;lt;ref name=&amp;quot;ref4&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition&amp;lt;ref name=&amp;quot;ref6&amp;quot; /&amp;gt;.&lt;br /&gt;

&lt;br /&gt;
The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested &amp;lt;ref name=&amp;quot;ref5&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast&amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;.&lt;br /&gt;

&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger.&lt;br /&gt;
&lt;br /&gt;
In Monachello's study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes &amp;lt;ref name=&amp;quot;ref3&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2- into the vacuole (negative current), when cytosolic  [NO3 2-] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa &amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. &lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis&amp;lt;ref name=&amp;quot;ref4&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition&amp;lt;ref name=&amp;quot;ref6&amp;quot; /&amp;gt;.&lt;br /&gt;

&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger.&lt;br /&gt;
&lt;br /&gt;
In Monachello's study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes &amp;lt;ref name=&amp;quot;ref3&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2- into the vacuole (negative current), when cytosolic  [NO3 2-] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa &amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. &lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis&amp;lt;ref name=&amp;quot;ref4&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition&amp;lt;ref name=&amp;quot;ref6&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Expression ==&lt;br /&gt;
&lt;br /&gt;
The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested &amp;lt;ref name=&amp;quot;ref5&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast&amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;.&lt;br /&gt;

The AtCLC proteins were predicted to consist of 9–11 transmembrane spanning domains and two conserved CBS domains at the carboxyl end. These domains were similar in sizes and positions to those of CLC-0 and mammalian CLCs.&amp;lt;ref name=&amp;quot;ref2&amp;quot; /&amp;gt;.&lt;br /&gt;

&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger.&lt;br /&gt;
&lt;br /&gt;
In Monachello's study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes &amp;lt;ref name=&amp;quot;ref3&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2- into the vacuole (negative current), when cytosolic  [NO3 2-] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa &amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. &lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis&amp;lt;ref name=&amp;quot;ref4&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition&amp;lt;ref name=&amp;quot;ref6&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Expression ==&lt;br /&gt;
&lt;br /&gt;
The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested &amp;lt;ref name=&amp;quot;ref5&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast&amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;.&lt;br /&gt;

[[File:08.jpg|200px|thumb|left|Phylogeny of predicted AtCLC proteins.]]&lt;br /&gt;
The AtCLC proteins were predicted to consist of 9–11 transmembrane spanning domains and two conserved CBS domains at the carboxyl end. These domains were similar in sizes and positions to those of CLC-0 and mammalian CLCs.&amp;lt;ref name=&amp;quot;ref2&amp;quot; /&amp;gt;.&lt;br /&gt;

&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger.&lt;br /&gt;
&lt;br /&gt;
In Monachello's study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes &amp;lt;ref name=&amp;quot;ref3&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2- into the vacuole (negative current), when cytosolic  [NO3 2-] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa &amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. &lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis&amp;lt;ref name=&amp;quot;ref4&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition&amp;lt;ref name=&amp;quot;ref6&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Expression ==&lt;br /&gt;
&lt;br /&gt;
The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested &amp;lt;ref name=&amp;quot;ref5&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast&amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;.&lt;br /&gt;

== Evolution ==&lt;br /&gt;
[[File:08.jpg|200px|thumb|left|Phylogeny of predicted AtCLC proteins.]]&lt;br /&gt;
The AtCLC proteins were predicted to consist of 9–11 transmembrane spanning domains and two conserved CBS domains at the carboxyl end. These domains were similar in sizes and positions to those of CLC-0 and mammalian CLCs.&amp;lt;ref name=&amp;quot;ref2&amp;quot; /&amp;gt;.&lt;br /&gt;

&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger.&lt;br /&gt;
&lt;br /&gt;
In Monachello's study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes &amp;lt;ref name=&amp;quot;ref3&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2- into the vacuole (negative current), when cytosolic  [NO3 2-] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa &amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. &lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis&amp;lt;ref name=&amp;quot;ref4&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition&amp;lt;ref name=&amp;quot;ref6&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Expression ==&lt;br /&gt;
&lt;br /&gt;
The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested &amp;lt;ref name=&amp;quot;ref5&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast&amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;.&lt;br /&gt;

== Evolution ==&lt;br /&gt;
[[File:08.jpg|200px|thumb|left|Phylogeny of predicted AtCLC proteins.]]&lt;br /&gt;
The AtCLC proteins were predicted to consist of 9–11 transmembrane spanning domains and two conserved CBS domains at the carboxyl end. These domains were similar in sizes and positions to those of CLC-0 and mammalian CLCs.&amp;lt;ref name=&amp;quot;ref2&amp;quot; /&amp;gt;.&lt;br /&gt;

&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger.&lt;br /&gt;
&lt;br /&gt;
In Monachello's study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes &amp;lt;ref name=&amp;quot;ref3&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2- into the vacuole (negative current), when cytosolic  [NO3 2-] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa &amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. &lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis&amp;lt;ref name=&amp;quot;ref4&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition&amp;lt;ref name=&amp;quot;ref6&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Expression ==&lt;br /&gt;
&lt;br /&gt;
The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested &amp;lt;ref name=&amp;quot;ref5&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast&amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;.&lt;br /&gt;

== Evolution ==&lt;br /&gt;
[[File:08.jpg|200px|thumb|left|Phylogeny of predicted AtCLC proteins.]]&lt;br /&gt;
The AtCLC proteins were predicted to consist of 9–11 transmembrane spanning domains and two conserved CBS domains at the carboxyl end. These domains were similar in sizes and positions to those of CLC-0 and mammalian CLCs.&amp;lt;ref name=&amp;quot;ref2&amp;quot; /&amp;gt;.&lt;br /&gt;

&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger.&lt;br /&gt;
&lt;br /&gt;
In Monachello's study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes &amp;lt;ref name=&amp;quot;ref3&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2- into the vacuole (negative current), when cytosolic  [NO3 2-] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa &amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. &lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis&amp;lt;ref name=&amp;quot;ref4&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition&amp;lt;ref name=&amp;quot;ref6&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Expression ==&lt;br /&gt;
&lt;br /&gt;
The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested &amp;lt;ref name=&amp;quot;ref5&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast&amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;.&lt;br /&gt;

== Evolution ==&lt;br /&gt;
[[File:08.jpg|200px|thumb|left|figure 8]]&lt;br /&gt;
The AtCLC proteins were predicted to consist of 9–11 transmembrane spanning domains and two conserved CBS domains at the carboxyl end. These domains were similar in sizes and positions to those of CLC-0 and mammalian CLCs.&amp;lt;ref name=&amp;quot;ref2&amp;quot; /&amp;gt;.&lt;br /&gt;

&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger.&lt;br /&gt;
&lt;br /&gt;
In Monachello's study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes &amp;lt;ref name=&amp;quot;ref3&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2- into the vacuole (negative current), when cytosolic  [NO3 2-] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa &amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. &lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis&amp;lt;ref name=&amp;quot;ref4&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition&amp;lt;ref name=&amp;quot;ref6&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Expression ==&lt;br /&gt;
&lt;br /&gt;
The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested &amp;lt;ref name=&amp;quot;ref5&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast&amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
== Evolution ==&lt;br /&gt;
[[File:08.jpg|200px|thumb|left|figure 8]]&lt;br /&gt;
The AtCLC proteins were predicted to consist of 9–11 transmembrane spanning domains and two conserved CBS domains at the carboxyl end. These domains were similar in sizes and positions to those of CLC-0 and mammalian CLCs.&amp;lt;ref name=&amp;quot;ref2&amp;quot; /&amp;gt;.&lt;br /&gt;

&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger.&lt;br /&gt;
&lt;br /&gt;
In Monachello's study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes &amp;lt;ref name=&amp;quot;ref3&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2- into the vacuole (negative current), when cytosolic  [NO3 2-] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa &amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. &lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis&amp;lt;ref name=&amp;quot;ref4&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition&amp;lt;ref name=&amp;quot;ref6&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Expression ==&lt;br /&gt;
&lt;br /&gt;
The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested &amp;lt;ref name=&amp;quot;ref5&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast&amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
== Evolution ==&lt;br /&gt;
[[File:08.jpg|220px|thumb|left|figure 8]]&lt;br /&gt;
The AtCLC proteins were predicted to consist of 9–11 transmembrane spanning domains and two conserved CBS domains at the carboxyl end. These domains were similar in sizes and positions to those of CLC-0 and mammalian CLCs.&amp;lt;ref name=&amp;quot;ref2&amp;quot; /&amp;gt;.&lt;br /&gt;

&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger.&lt;br /&gt;
&lt;br /&gt;
In Monachello's study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes &amp;lt;ref name=&amp;quot;ref3&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2- into the vacuole (negative current), when cytosolic  [NO3 2-] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa &amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. &lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis&amp;lt;ref name=&amp;quot;ref4&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition&amp;lt;ref name=&amp;quot;ref6&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Expression ==&lt;br /&gt;
&lt;br /&gt;
The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested &amp;lt;ref name=&amp;quot;ref5&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast&amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
== Evolution ==&lt;br /&gt;
[[File:08.jpg|250px|thumb|left|figure 8]]&lt;br /&gt;
The AtCLC proteins were predicted to consist of 9–11 transmembrane spanning domains and two conserved CBS domains at the carboxyl end. These domains were similar in sizes and positions to those of CLC-0 and mammalian CLCs.&amp;lt;ref name=&amp;quot;ref2&amp;quot; /&amp;gt;.&lt;br /&gt;

&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger.&lt;br /&gt;
&lt;br /&gt;
In Monachello's study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes &amp;lt;ref name=&amp;quot;ref3&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2- into the vacuole (negative current), when cytosolic  [NO3 2-] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa &amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. &lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis&amp;lt;ref name=&amp;quot;ref4&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition&amp;lt;ref name=&amp;quot;ref6&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Expression ==&lt;br /&gt;
&lt;br /&gt;
The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested &amp;lt;ref name=&amp;quot;ref5&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast&amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
== Evolution ==&lt;br /&gt;
[[File:08.jpg|300px|thumb|left|figure 8]]&lt;br /&gt;
The AtCLC proteins were predicted to consist of 9–11 transmembrane spanning domains and two conserved CBS domains at the carboxyl end. These domains were similar in sizes and positions to those of CLC-0 and mammalian CLCs.&amp;lt;ref name=&amp;quot;ref2&amp;quot; /&amp;gt;.&lt;br /&gt;

[[File:Vacuolar chloride is transported differently.JPG|right|200px|thumb|Vacuolar chloride is transported differently by native AtCLCaWT andthe mutant AtCLCaP160S.]]&lt;br /&gt;

&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger.&lt;br /&gt;
&lt;br /&gt;
In Monachello's study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes &amp;lt;ref name=&amp;quot;ref3&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2- into the vacuole (negative current), when cytosolic  [NO3 2-] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa &amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. &lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis&amp;lt;ref name=&amp;quot;ref4&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition&amp;lt;ref name=&amp;quot;ref6&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Expression ==&lt;br /&gt;
&lt;br /&gt;
The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested &amp;lt;ref name=&amp;quot;ref5&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast&amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
== Evolution ==&lt;br /&gt;
[[File:08.jpg|300px|thumb|right|figure 8]]&lt;br /&gt;
The AtCLC proteins were predicted to consist of 9–11 transmembrane spanning domains and two conserved CBS domains at the carboxyl end. These domains were similar in sizes and positions to those of CLC-0 and mammalian CLCs.&amp;lt;ref name=&amp;quot;ref2&amp;quot; /&amp;gt;.&lt;br /&gt;

== Function ==&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger.&lt;br /&gt;
&lt;br /&gt;
In Monachello's study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes &amp;lt;ref name=&amp;quot;ref3&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2- into the vacuole (negative current), when cytosolic  [NO3 2-] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa &amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. &lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis&amp;lt;ref name=&amp;quot;ref4&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition&amp;lt;ref name=&amp;quot;ref6&amp;quot; /&amp;gt;.&lt;br /&gt;

&lt;br /&gt;
== Expression ==&lt;br /&gt;
&lt;br /&gt;
The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested &amp;lt;ref name=&amp;quot;ref5&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast&amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
== Evolution ==&lt;br /&gt;
[[File:08.jpg|300px|thumb|right|figure 8]]&lt;br /&gt;
The AtCLC proteins were predicted to consist of 9–11 transmembrane spanning domains and two conserved CBS domains at the carboxyl end. These domains were similar in sizes and positions to those of CLC-0 and mammalian CLCs.&amp;lt;ref name=&amp;quot;ref2&amp;quot; /&amp;gt;.&lt;br /&gt;

&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger.&lt;br /&gt;
&lt;br /&gt;
In Monachello's study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes &amp;lt;ref name=&amp;quot;ref3&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2- into the vacuole (negative current), when cytosolic  [NO3 2-] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa &amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. &lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis&amp;lt;ref name=&amp;quot;ref4&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition&amp;lt;ref name=&amp;quot;ref6&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
== Expression ==&lt;br /&gt;
&lt;br /&gt;
The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested &amp;lt;ref name=&amp;quot;ref5&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast&amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
== Evolution ==&lt;br /&gt;
[[File:08.jpg|300px|thumb|right|figure 8]]&lt;br /&gt;
The AtCLC proteins were predicted to consist of 9–11 transmembrane spanning domains and two conserved CBS domains at the carboxyl end. These domains were similar in sizes and positions to those of CLC-0 and mammalian CLCs.&amp;lt;ref name=&amp;quot;ref2&amp;quot; /&amp;gt;.&lt;br /&gt;

[[File:Representation of the AtCLCaNO32Ht antiporter in a plant cell.JPG|right|300px|thumb|Representation of the AtCLCaNO32Ht antiporter in a plant cell.]]&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger.&lt;br /&gt;
&lt;br /&gt;
In Monachello's study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes &amp;lt;ref name=&amp;quot;ref3&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2- into the vacuole (negative current), when cytosolic  [NO3 2-] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa &amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. &lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis&amp;lt;ref name=&amp;quot;ref4&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition&amp;lt;ref name=&amp;quot;ref6&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
== Expression ==&lt;br /&gt;
&lt;br /&gt;
The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested &amp;lt;ref name=&amp;quot;ref5&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast&amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
== Evolution ==&lt;br /&gt;
[[File:08.jpg|300px|thumb|right|figure 8]]&lt;br /&gt;
The AtCLC proteins were predicted to consist of 9–11 transmembrane spanning domains and two conserved CBS domains at the carboxyl end. These domains were similar in sizes and positions to those of CLC-0 and mammalian CLCs.&amp;lt;ref name=&amp;quot;ref2&amp;quot; /&amp;gt;.&lt;br /&gt;

= Annotated Information =&lt;br /&gt;
&lt;br /&gt;
== Function ==&lt;br /&gt;
&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger.&lt;br /&gt;
&lt;br /&gt;
In Monachello's study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes &amp;lt;ref name=&amp;quot;ref3&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2- into the vacuole (negative current), when cytosolic  [NO3 2-] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa &amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. &lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis&amp;lt;ref name=&amp;quot;ref4&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition&amp;lt;ref name=&amp;quot;ref6&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
== Expression ==&lt;br /&gt;
&lt;br /&gt;
The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested &amp;lt;ref name=&amp;quot;ref5&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast&amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
== Evolution ==&lt;br /&gt;
[[File:08.jpg|300px|thumb|right|figure 8]]&lt;br /&gt;
The AtCLC proteins were predicted to consist of 9–11 transmembrane spanning domains and two conserved CBS domains at the carboxyl end. These domains were similar in sizes and positions to those of CLC-0 and mammalian CLCs.&amp;lt;ref name=&amp;quot;ref2&amp;quot; /&amp;gt;.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;&lt;br /&gt;
= Annotated Information =&lt;br /&gt;
&lt;br /&gt;
== Function ==&lt;br /&gt;
&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger.&lt;br /&gt;
&lt;br /&gt;
In Monachello's study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes &amp;lt;ref name=&amp;quot;ref3&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2- into the vacuole (negative current), when cytosolic  [NO3 2-] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa &amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. &lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis&amp;lt;ref name=&amp;quot;ref4&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition&amp;lt;ref name=&amp;quot;ref6&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
== Expression ==&lt;br /&gt;
&lt;br /&gt;
The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested &amp;lt;ref name=&amp;quot;ref5&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast&amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
== Evolution ==&lt;br /&gt;
&lt;br /&gt;
The AtCLC proteins were predicted to consist of 9–11 transmembrane spanning domains and two conserved CBS domains at the carboxyl end. These domains were similar in sizes and positions to those of CLC-0 and mammalian CLCs.&amp;lt;ref name=&amp;quot;ref2&amp;quot; /&amp;gt;.&lt;br /&gt;

&lt;br /&gt;
== Function ==&lt;br /&gt;
&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger.&lt;br /&gt;
&lt;br /&gt;
In Monachello's study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes &amp;lt;ref name=&amp;quot;ref3&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2- into the vacuole (negative current), when cytosolic  [NO3 2-] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa &amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. &lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis&amp;lt;ref name=&amp;quot;ref4&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition&amp;lt;ref name=&amp;quot;ref6&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
== Expression ==&lt;br /&gt;
&lt;br /&gt;
The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested &amp;lt;ref name=&amp;quot;ref5&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast&amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;

Phylogeny of predicted AtCLC proteins.&lt;br /&gt;
(A) Scaled graphic representation of different domains of CLCs from Arabidopsis as well as from E. Coli (EcCLC-a, EcCLCb) and Torpedo marmorata (CLC-0). The relative position of each TM region and CBS domain is modified according to PRED-TMR and SMART, respectively. Each black bar stands for a TM region and gray boxes correspond to CBS domains as indicated inside. Accession numbers of the CLC protein sequences are available in Supplemental Tables 2–4. (B) Plant CLC proteins are grouped into two distinct subclasses. Neighbor-joining protein sequence phylogeny was performed using MEGA4.0. Bootstrap values are shown on the branch points of the tree. Subclass Iand II are indicated by two curves separately. Accession numbers of the sequences included are provided in Supplemental Tables 2–4. (C) Amino acid sequence alignments of two CBS domains of AtCLCs. The corresponding CBS domain was lined on the top of the sequences.&amp;lt;ref name=&amp;quot;ref2&amp;quot; /&amp;gt;.&lt;br /&gt;

&lt;br /&gt;
== Function ==&lt;br /&gt;
&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger.&lt;br /&gt;
&lt;br /&gt;
In Monachello's study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes &amp;lt;ref name=&amp;quot;ref3&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2- into the vacuole (negative current), when cytosolic  [NO3 2-] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa &amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. &lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis&amp;lt;ref name=&amp;quot;ref4&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition&amp;lt;ref name=&amp;quot;ref6&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
== Expression ==&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested.&amp;lt;ref name=&amp;quot;ref5&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast&amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;.。&lt;br /&gt;
&lt;br /&gt;

Phylogeny of predicted AtCLC proteins.&lt;br /&gt;
(A) Scaled graphic representation of different domains of CLCs from Arabidopsis as well as from E. Coli (EcCLC-a, EcCLCb) and Torpedo marmorata (CLC-0). The relative position of each TM region and CBS domain is modified according to PRED-TMR and SMART, respectively. Each black bar stands for a TM region and gray boxes correspond to CBS domains as indicated inside. Accession numbers of the CLC protein sequences are available in Supplemental Tables 2–4. (B) Plant CLC proteins are grouped into two distinct subclasses. Neighbor-joining protein sequence phylogeny was performed using MEGA4.0. Bootstrap values are shown on the branch points of the tree. Subclass Iand II are indicated by two curves separately. Accession numbers of the sequences included are provided in Supplemental Tables 2–4. (C) Amino acid sequence alignments of two CBS domains of AtCLCs. The corresponding CBS domain was lined on the top of the sequences.&amp;lt;ref name=&amp;quot;ref2&amp;quot; /&amp;gt;.&lt;br /&gt;

&lt;br /&gt;
== Function ==&lt;br /&gt;
&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger. electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2- into the vacuole (negative current), when cytosolic  [NO3 2-] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa &amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. Finally, the present findings illustrate the exchanger mechanism of a CLC protein in the native membrane system and answer the biological question regarding CLC antiporter function in an intracellular organelle. &lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis&amp;lt;ref name=&amp;quot;ref4&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Vacuolar chloride is transported differently by native AtCLCaWT andthe mutant AtCLCaP160S. Thus, compared with AtCLCaWT, AtCLCaP160S shows adecrease of the anion conductance directed to the vacuoleupon exchange of the cytosolic solution from Cl) to NO3 This indicates that alteration of proline at position 160 to serine in the selectivity filter impairs NO3) import into the vacuole, and thus P160 may be important for the physiological function of AtCLCa in NO3 ) accumulation in vacuoles.&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain&amp;lt;ref name=&amp;quot;ref6&amp;quot; /&amp;gt;. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition.&lt;br /&gt;

&lt;br /&gt;
In this study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes &amp;lt;ref name=&amp;quot;ref3&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
== Expression ==&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested.&amp;lt;ref name=&amp;quot;ref5&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast&amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;.。&lt;br /&gt;

&lt;br /&gt;
== Function ==&lt;br /&gt;
&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger. electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2- into the vacuole (negative current), when cytosolic  [NO3 2-] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa &amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. Finally, the present findings illustrate the exchanger mechanism of a CLC protein in the native membrane system and answer the biological question regarding CLC antiporter function in an intracellular organelle. &lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis&amp;lt;ref name=&amp;quot;ref4&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Vacuolar chloride is transported differently by native AtCLCaWT andthe mutant AtCLCaP160S. Thus, compared with AtCLCaWT, AtCLCaP160S shows adecrease of the anion conductance directed to the vacuoleupon exchange of the cytosolic solution from Cl) to NO3 This indicates that alteration of proline at position 160 to serine in the selectivity filter impairs NO3) import into the vacuole, and thus P160 may be important for the physiological function of AtCLCa in NO3 ) accumulation in vacuoles.&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain&amp;lt;ref name=&amp;quot;ref6&amp;quot; /&amp;gt;. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition.&lt;br /&gt;

&lt;br /&gt;
In this study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes &amp;lt;ref name=&amp;quot;ref3&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
== Expression ==&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested.&amp;lt;ref name=&amp;quot;ref5&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast&amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;.。&lt;br /&gt;

== Function ==&lt;br /&gt;
&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. &lt;br /&gt;
CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger. electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2 into the vacuole (negative current), when cytosolic  [NO3 2-] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa&amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. Finally, the present findings illustrate the exchanger mechanism of a CLC protein in the native membrane system and answer the biological question regarding CLC antiporter function in an intracellular organelle. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
Representation of the AtCLCaNO32/Ht antiporter in a plant cell&lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis&amp;lt;ref name=&amp;quot;ref4&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
Vacuolar chloride is transported differently by native AtCLCaWT andthe mutant AtCLCaP160S. Thus, compared with AtCLCaWT, AtCLCaP160S shows adecrease of the anion conductance directed to the vacuoleupon exchange of the cytosolic solution from Cl) to NO3 This indicates that alteration of proline at position 160 to serine in the selectivity filter impairs NO3) import into the vacuole, and thus P160 may be important for the physiological function of AtCLCa in NO3 ) accumulation in vacuoles.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain&amp;lt;ref name=&amp;quot;ref6&amp;quot; /&amp;gt;. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
In this study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes &amp;lt;ref name=&amp;quot;ref3&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
== Expression ==&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested.&amp;lt;ref name=&amp;quot;ref5&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast&amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;.。&lt;br /&gt;
&lt;br /&gt;

== Function ==&lt;br /&gt;
&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. &lt;br /&gt;
CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger. electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2 into the vacuole (negative current), when cytosolic  [NO3 2-] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa&amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. Finally, the present findings illustrate the exchanger mechanism of a CLC protein in the native membrane system and answer the biological question regarding CLC antiporter function in an intracellular organelle. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
Representation of the AtCLCaNO32/Ht antiporter in a plant cell&lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis&amp;lt;ref name=&amp;quot;ref4&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
Vacuolar chloride is transported differently by native AtCLCaWT andthe mutant AtCLCaP160S. Thus, compared with AtCLCaWT, AtCLCaP160S shows adecrease of the anion conductance directed to the vacuoleupon exchange of the cytosolic solution from Cl) to NO3 This indicates that alteration of proline at position 160 to serine in the selectivity filter impairs NO3) import into the vacuole, and thus P160 may be important for the physiological function of AtCLCa in NO3 ) accumulation in vacuoles.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain&amp;lt;ref name=&amp;quot;ref6&amp;quot; /&amp;gt;. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
In this study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes &amp;lt;ref name=&amp;quot;ref3&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
== Expression ==&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested.&amp;lt;ref name=&amp;quot;ref5&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast&amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;.。&lt;br /&gt;
&lt;br /&gt;

The relative position of each TM region and CBS domain is modified according to PRED-TMR and SMART, respectively. Each black bar stands for a TM region and gray boxes correspond to CBS domains as indicated inside. Accession numbers of the CLC protein sequences are available in Supplemental Tables 2–4. (B) Plant CLC proteins are grouped into two distinct subclasses. Neighbor-joining protein sequence phylogeny was performed using MEGA4.0. Bootstrap values are shown on the branch points of the tree. Subclass Iand II are indicated by two curves separately. Accession numbers of the sequences included are provided in Supplemental Tables 2–4. (C) Amino acid sequence alignments of two CBS domains of AtCLCs. The corresponding CBS domain was lined on the top of the sequences.&lt;br /&gt;

== Function ==&lt;br /&gt;
&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. &lt;br /&gt;
CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger. electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2 into the vacuole (negative current), when cytosolic  [NO3 2-] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa&amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;.. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. Finally, the present findings illustrate the exchanger mechanism of a CLC protein in the native membrane system and answer the biological question regarding CLC antiporter function in an intracellular organelle. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
Representation of the AtCLCaNO32/Ht antiporter in a plant cell&lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis.&amp;lt;ref name=&amp;quot;ref4&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
Vacuolar chloride is transported differently by native AtCLCaWT andthe mutant AtCLCaP160S. Thus, compared with AtCLCaWT, AtCLCaP160S shows adecrease of the anion conductance directed to the vacuoleupon exchange of the cytosolic solution from Cl) to NO3 This indicates that alteration of proline at position 160 to serine in the selectivity filter impairs NO3) import into the vacuole, and thus P160 may be important for the physiological function of AtCLCa in NO3 ) accumulation in vacuoles.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain&amp;lt;ref name=&amp;quot;ref6&amp;quot; /&amp;gt;.. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition.&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
In this study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes.&amp;lt;ref name=&amp;quot;ref3&amp;quot; /&amp;gt;.&lt;br /&gt;

== Expression ==&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested.&amp;lt;ref name=&amp;quot;ref5&amp;quot; /&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast&amp;lt;ref name=&amp;quot;ref1&amp;quot; /&amp;gt;.。&lt;br /&gt;
&lt;br /&gt;

== Function ==&lt;br /&gt;
&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. &lt;br /&gt;
CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger. electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2 into the vacuole (negative current), when cytosolic  [NO3 2-] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa【1】. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. Finally, the present findings illustrate the exchanger mechanism of a CLC protein in the native membrane system and answer the biological question regarding CLC antiporter function in an intracellular organelle. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
Representation of the AtCLCaNO32/Ht antiporter in a plant cell&lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis.【4】&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
Vacuolar chloride is transported differently by native AtCLCaWT andthe mutant AtCLCaP160S. Thus, compared with AtCLCaWT, AtCLCaP160S shows adecrease of the anion conductance directed to the vacuoleupon exchange of the cytosolic solution from Cl) to NO3 This indicates that alteration of proline at position 160 to serine in the selectivity filter impairs NO3) import into the vacuole, and thus P160 may be important for the physiological function of AtCLCa in NO3 ) accumulation in vacuoles.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain【6】. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
【3】In this study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes.&lt;br /&gt;
&lt;br /&gt;

== Expression ==&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
【5】The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast【1】。&lt;br /&gt;
&lt;br /&gt;

(A) Scaled graphic representation of different domains of CLCs from Arabidopsis as well as from E. Coli (EcCLC-a, EcCLCb) and Torpedo marmorata (CLC-0). The relative position of each TM region and CBS domain is modified according to PRED-TMR and SMART, respectively. Each black bar stands for a TM region and gray boxes correspond to CBS domains as indicated inside. Accession numbers of the CLC protein sequences are available in Supplemental Tables 2–4. (B) Plant CLC proteins are grouped into two distinct subclasses. Neighbor-joining protein sequence phylogeny was performed using MEGA4.0. Bootstrap values are shown on the branch points of the tree. Subclass Iand II are indicated by two curves separately. Accession numbers of the sequences included are provided in Supplemental Tables 2–4. (C) Amino acid sequence alignments of two CBS domains of AtCLCs. The corresponding CBS domain was lined on the top of the sequences.&lt;br /&gt;

== Function ==&lt;br /&gt;
&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. &lt;br /&gt;
CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger. electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2 into the vacuole (negative current), when cytosolic  [NO3 2-] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa【1】. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. Finally, the present findings illustrate the exchanger mechanism of a CLC protein in the native membrane system and answer the biological question regarding CLC antiporter function in an intracellular organelle. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
Representation of the AtCLCaNO32/Ht antiporter in a plant cell&lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis.【4】&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
Vacuolar chloride is transported differently by native AtCLCaWT andthe mutant AtCLCaP160S. Thus, compared with AtCLCaWT, AtCLCaP160S shows adecrease of the anion conductance directed to the vacuoleupon exchange of the cytosolic solution from Cl) to NO3 This indicates that alteration of proline at position 160 to serine in the selectivity filter impairs NO3) import into the vacuole, and thus P160 may be important for the physiological function of AtCLCa in NO3 ) accumulation in vacuoles.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain【6】. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
【3】In this study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
== Expression ==&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
【5】The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast【1】。&lt;br /&gt;

(A) Scaled graphic representation of different domains of CLCs from Arabidopsis as well as from E. Coli (EcCLC-a, EcCLCb) and Torpedo marmorata (CLC-0). The relative position of each TM region and CBS domain is modified according to PRED-TMR and SMART, respectively. Each black bar stands for a TM region and gray boxes correspond to CBS domains as indicated inside. Accession numbers of the CLC protein sequences are available in Supplemental Tables 2–4. (B) Plant CLC proteins are grouped into two distinct subclasses. Neighbor-joining protein sequence phylogeny was performed using MEGA4.0. Bootstrap values are shown on the branch points of the tree. Subclass Iand II are indicated by two curves separately. Accession numbers of the sequences included are provided in Supplemental Tables 2–4. (C) Amino acid sequence alignments of two CBS domains of AtCLCs. The corresponding CBS domain was lined on the top of the sequences.&lt;br /&gt;

&lt;br /&gt;
== 1.1 Function ==&lt;br /&gt;
&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. &lt;br /&gt;
CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger. electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2 into the vacuole (negative current), when cytosolic  [NO3 2-] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa【1】. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. Finally, the present findings illustrate the exchanger mechanism of a CLC protein in the native membrane system and answer the biological question regarding CLC antiporter function in an intracellular organelle. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
Representation of the AtCLCaNO32/Ht antiporter in a plant cell&lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis.【4】&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
Vacuolar chloride is transported differently by native AtCLCaWT andthe mutant AtCLCaP160S. Thus, compared with AtCLCaWT, AtCLCaP160S shows adecrease of the anion conductance directed to the vacuoleupon exchange of the cytosolic solution from Cl) to NO3 This indicates that alteration of proline at position 160 to serine in the selectivity filter impairs NO3) import into the vacuole, and thus P160 may be important for the physiological function of AtCLCa in NO3 ) accumulation in vacuoles.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain【6】. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
【3】In this study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes.&lt;br /&gt;
&lt;br /&gt;

== 1.2 Expression ==&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
【5】The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast【1】。&lt;br /&gt;
&lt;br /&gt;

(A) Scaled graphic representation of different domains of CLCs from Arabidopsis as well as from E. Coli (EcCLC-a, EcCLCb) and Torpedo marmorata (CLC-0). The relative position of each TM region and CBS domain is modified according to PRED-TMR and SMART, respectively. Each black bar stands for a TM region and gray boxes correspond to CBS domains as indicated inside. Accession numbers of the CLC protein sequences are available in Supplemental Tables 2–4. (B) Plant CLC proteins are grouped into two distinct subclasses. Neighbor-joining protein sequence phylogeny was performed using MEGA4.0. Bootstrap values are shown on the branch points of the tree. Subclass Iand II are indicated by two curves separately. Accession numbers of the sequences included are provided in Supplemental Tables 2–4. (C) Amino acid sequence alignments of two CBS domains of AtCLCs. The corresponding CBS domain was lined on the top of the sequences.&lt;br /&gt;

&lt;br /&gt;
== 1.1 Function ==&lt;br /&gt;
&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. &lt;br /&gt;
CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger. electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2 into the vacuole (negative current), when cytosolic  [NO3 2-] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa【1】. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. Finally, the present findings illustrate the exchanger mechanism of a CLC protein in the native membrane system and answer the biological question regarding CLC antiporter function in an intracellular organelle. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
Representation of the AtCLCaNO32/Ht antiporter in a plant cell&lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis.【4】&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
Vacuolar chloride is transported differently by native AtCLCaWT andthe mutant AtCLCaP160S. Thus, compared with AtCLCaWT, AtCLCaP160S shows adecrease of the anion conductance directed to the vacuoleupon exchange of the cytosolic solution from Cl) to NO3 This indicates that alteration of proline at position 160 to serine in the selectivity filter impairs NO3) import into the vacuole, and thus P160 may be important for the physiological function of AtCLCa in NO3 ) accumulation in vacuoles.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain【6】. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
【3】In this study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes.&lt;br /&gt;
&lt;br /&gt;

== 1.2 Expression ==&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
【5】The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast【1】。&lt;br /&gt;
&lt;br /&gt;

(A) Scaled graphic representation of different domains of CLCs from Arabidopsis as well as from E. Coli (EcCLC-a, EcCLCb) and Torpedo marmorata (CLC-0). The relative position of each TM region and CBS domain is modified according to PRED-TMR and SMART, respectively. Each black bar stands for a TM region and gray boxes correspond to CBS domains as indicated inside. Accession numbers of the CLC protein sequences are available in Supplemental Tables 2–4. (B) Plant CLC proteins are grouped into two distinct subclasses. Neighbor-joining protein sequence phylogeny was performed using MEGA4.0. Bootstrap values are shown on the branch points of the tree. Subclass Iand II are indicated by two curves separately. Accession numbers of the sequences included are provided in Supplemental Tables 2–4. (C) Amino acid sequence alignments of two CBS domains of AtCLCs. The corresponding CBS domain was lined on the top of the sequences.&lt;br /&gt;

&lt;br /&gt;
== 1.1 Function ==&lt;br /&gt;
&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. &lt;br /&gt;
CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger. electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2 into the vacuole (negative current), when cytosolic  [NO3 2-] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa【1】. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. Finally, the present findings illustrate the exchanger mechanism of a CLC protein in the native membrane system and answer the biological question regarding CLC antiporter function in an intracellular organelle. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
Representation of the AtCLCaNO32/Ht antiporter in a plant cell&lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis.【4】&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
Vacuolar chloride is transported differently by native AtCLCaWT andthe mutant AtCLCaP160S. Thus, compared with AtCLCaWT, AtCLCaP160S shows adecrease of the anion conductance directed to the vacuoleupon exchange of the cytosolic solution from Cl) to NO3 This indicates that alteration of proline at position 160 to serine in the selectivity filter impairs NO3) import into the vacuole, and thus P160 may be important for the physiological function of AtCLCa in NO3 ) accumulation in vacuoles.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain【6】. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
【3】In this study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes.&lt;br /&gt;
&lt;br /&gt;

== 1.2 Expression ==&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
【5】The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast【1】。&lt;br /&gt;
&lt;br /&gt;

Phylogeny of predicted AtCLC proteins.&lt;br /&gt;
(A) Scaled graphic representation of different domains of CLCs from Arabidopsis as well as from E. Coli (EcCLC-a, EcCLCb) and Torpedo marmorata (CLC-0). The relative position of each TM region and CBS domain is modified according to PRED-TMR and SMART, respectively. Each black bar stands for a TM region and gray boxes correspond to CBS domains as indicated inside. Accession numbers of the CLC protein sequences are available in Supplemental Tables 2–4. (B) Plant CLC proteins are grouped into two distinct subclasses. Neighbor-joining protein sequence phylogeny was performed using MEGA4.0. Bootstrap values are shown on the branch points of the tree. Subclass Iand II are indicated by two curves separately. Accession numbers of the sequences included are provided in Supplemental Tables 2–4. (C) Amino acid sequence alignments of two CBS domains of AtCLCs. The corresponding CBS domain was lined on the top of the sequences.&lt;br /&gt;

&lt;br /&gt;
== 1.1 Function ==&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. &lt;br /&gt;
CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger. &lt;br /&gt;
electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2 into the vacuole (negative current), when cytosolic  [NO3 2] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa【1】. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. Finally, the present findings illustrate the exchanger mechanism of a CLC protein in the native membrane system and answer the biological question23 regarding CLC antiporter function in an intracellular organelle. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
Representation of the AtCLCaNO32/Ht antiporter in a plant cell&lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis.【4】&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
Vacuolar chloride is transported differently by native AtCLCaWT andthe mutant AtCLCaP160S. Thus, compared with AtCLCaWT, AtCLCaP160S shows adecrease of the anion conductance directed to the vacuoleupon exchange of the cytosolic solution from Cl) to NO3 This indicates that alteration of proline at position 160 to serine in the selectivity filter impairs NO3) import into the vacuole, and thus P160 may be important for the physiological function of AtCLCa in NO3 ) accumulation in vacuoles.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain【6】. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
【3】In this study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
1.2 Expression&lt;br /&gt;
&lt;br /&gt;
【5】The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast【1】。&lt;br /&gt;

&lt;div&gt;1 Annotated Information&lt;br /&gt;
1.1 Function&lt;br /&gt;
AtCLC-a, a member of the CLC family of anion transporters, is involved mainly in nitrate storage in the vacuole. &lt;br /&gt;
CLCa (AtCLCa) is localized to an intracellular membrane, the tonoplast of the plant vacuole, with anion transport ability. AtCLCa is able to accumulate specifically nitrate in the vacuole and behaves as a NO32-/H+ exchanger. &lt;br /&gt;
electrophysiological studies show that, at physiological membrane potentials, AtCLCa-mediated current is able to transport NO3 2 into the vacuole (negative current), when cytosolic  [NO3 2] is in a physiological range. Nevertheless, there is a clear discrepancy between the measured Erev and the Nernst potential for NO3 2. This observation demonstrates that other ions are transported by AtCLCa【1】. The high selectivity of AtCLCa for nitrate ions compared with chloride ions seems to be a peculiarity of this plant CLC and is in agreement with the clca knockout mutant phenotype. Finally, the present findings illustrate the exchanger mechanism of a CLC protein in the native membrane system and answer the biological question23 regarding CLC antiporter function in an intracellular organelle. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
Representation of the AtCLCaNO32/Ht antiporter in a plant cell&lt;br /&gt;
&lt;br /&gt;
By monitoring AtCLCa activity in its native environment, Stefanie Wege found that if proline 160 in AtCLCa is changed to a serine (AtCLCaP160S), the transporter loses its nitrate selectivity, but the anion proton exchange mechanism is unaffected. The results confirm the significance of this amino acid in the conserved selectivity filter of CLC proteins and highlight the importance of nitrate metabolism in Arabidopsis.【4】&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
Vacuolar chloride is transported differently by native AtCLCaWT andthe mutant AtCLCaP160S. Thus, compared with AtCLCaWT, AtCLCaP160S shows adecrease of the anion conductance directed to the vacuoleupon exchange of the cytosolic solution from Cl) to NO3 This indicates that alteration of proline at position 160 to serine in the selectivity filter impairs NO3) import into the vacuole, and thus P160 may be important for the physiological function of AtCLCa in NO3 ) accumulation in vacuoles.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
ATP reversibly inhibits AtCLCa by interacting with the C-terminal domain【6】. Applying the patch clamp technique to isolated Arabidopsis thaliana vacuoles, Alexis De Angeli demonstrate that ATP reduces AtCLCa activity with a maximum inhibition of 60%. ATP inhibition of nitrate influx into the vacuole at cytosolic physiological nitrate concentrations suggests that ATP modulation is physiologically relevant. ADP and AMP do not decrease the AtCLCa transport activity; nonetheless, AMP (but not ADP)  competes with ATP, preventing inhibition.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
【3】In this study, analyses of T-DNA insertion mutants within the AtClCa and AtClCe genes revealed common phenotypic traits: a lower endogenous nitrate content; a higher nitrite content; a reduced nitrate influx into the root; and a decreased expression of several genes encoding nitrate transporters. This set of nitrate-related phenotypes, displayed by clca and clce mutant plants, showed interconnecting roles of AtClCa and AtClCe in nitrate homeostasis involving two different endocellular membranes.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
1.2 Expression&lt;br /&gt;
&lt;br /&gt;
【5】The rice genome has been completely sequenced and comprises five CLC homologues, but only two members from Oryza sativa L., OsClC-1 and OsClC-2 have been characterized . The highest homology with the plant subgroup comprising AtClC-a to –g, OsClC-1 is expressed in most tissues, whereas OsClC-2 is expressed only in roots, nodes, internodes and leaf sheaths, but for both of them vacuolar localization has been suggested.&lt;br /&gt;
&lt;br /&gt;
To determine the subcellular localization of the AtCLCa protein,  green fluorescent protein (GFP) fusion proteins were transiently expressed in protoplasts from Arabidopsis cell suspensions. Confocal microscopy studies revealed a green fluorescent labelling that coincided with the tonoplast【1】。&lt;br /&gt;
