&lt;div&gt;Rice transcription regulator OsWRKY13 influences the functioning of more than 500 genes in multiple signalling pathways, with roles in disease resistance, redox homeostasis,abiotic stress responses, and development[1].&lt;br /&gt;
==Annotated Information==&lt;br /&gt;
&lt;br /&gt;
===Expression===&lt;br /&gt;
Comparative analysis of the genomic and cDNA sequences of OsWRKY13 (GenBank accession number EF143611) from resistant cultivar Minghui 63 (Oryza sativa subsp. indica) showed that the gene was 1,505 bp in length and had a coding region interrupted by two introns. The putative encoding product of OsWRKY13 consisted of 316 amino acids, which contained a WRKY motif, a zinc-finger motif, and a potential nuclear localization signal (Fig. 2A). According&lt;br /&gt;
to the classification of the WRKY superfamily (Eulgem et al. 2000), OsWRKY13 belongs to group II[2].&lt;br /&gt;
OsWRKY13 was overexpressed in cultivar Mudanjiang 8 (O.sativa subsp. japonica).&lt;br /&gt;
&lt;br /&gt;
[[File:Example.jpg]]===Function===&lt;br /&gt;
&lt;br /&gt;
Rice OsWRKY13 is a potentially important transcriptional regulator involved in multiple physiological processes. It mediates disease resistance to bacterial blight caused by Xanthomonas oryzae pv. oryzae (Xoo) and fungal blast caused by Magnaporthe grisea through activation of salicylic acid (SA)-dependent pathways and suppression of jasmonic acid (JA)-dependent pathways(FIG1); OsWRKY13 can bind to the W-box and W-box like cis-elements that are present in the promoters of some pathogen-induced defence-responsive genes [2,3]. Furthermore, genomewide analyses of the expression profiling of OsWRKY13-activated lines reveal that OsWRKY13 directly or indirectly regulates the expression of more than 500 genes [4].[[File:FiG1.png|300px|thumb|left|FIG1]]&lt;br /&gt;
&lt;br /&gt;
'''Fig. 1.''' Defense signaling model for the roles of OsWRKY13 in regulation of salicylic acid (SA)- and jasmonic acid (JA)-dependent pathways. Thick solid lines indicate direct action of OsWRKY13 has been confirmed by protein-DNA binding assays; thin solid lines, regulation may be executed by direct or indirect action; dotted lines, regulation has been confirmed in rice or other plant species; the line ending with arrow, activation; and the line ending with perpendicular short line indicates suppression.&lt;br /&gt;
&lt;br /&gt;
OsWRKY13 is also a potential regulator of other physiological processes during pathogen infection. It activates redox homeostasis by the glutathione/glutaredoxin system as well as the flavonoid biosynthesis pathway, which may enhance the biosynthesis of antimicrobial flavonoid phytoalexins [4]. OsWRKY13 inhibits the SNAC1-mediated abiotic stress defence pathway and terpenoid metabolism pathway to suppress salt and cold defence responses as well as to putatively retard rice growth and development[4]. Compared to the large number of differentially expressed genes in OsWRKY13-activated plants, however,most OsWRKY13-regulated pathways have yet to be elucidated.&lt;br /&gt;
To understand the transcriptional regulation of OsWRKY13, the types of transcription factors and conserved motifs in the promoter regions of the genes differentially expressed in OsWRKY13-activated plants were analyzed. The results suggest that the actions of OsWRKY13 on the expression of more than 500 genes are partitioned by different types of transcription factors through binding to distinctly distributed cis-acting elements in the promoters of OsWRKY13-upregulated and -downregulated genes. Furthermore, OsWRKY13 appears to bind preferentially to the promoters of downregulated genes in vitro, suggesting that it may function more as a negative transcriptional regulator[1].&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;Rice transcription regulator OsWRKY13 influences the functioning of more than 500 genes in multiple signalling pathways, with roles in disease resistance, redox homeostasis,abiotic stress responses, and development[1].&lt;br /&gt;
==Annotated Information==&lt;br /&gt;
&lt;br /&gt;
===Expression===&lt;br /&gt;
Comparative analysis of the genomic and cDNA sequences of OsWRKY13 (GenBank accession number EF143611) from resistant cultivar Minghui 63 (Oryza sativa subsp. indica) showed that the gene was 1,505 bp in length and had a coding region interrupted by two introns. The putative encoding product of OsWRKY13 consisted of 316 amino acids, which contained a WRKY motif, a zinc-finger motif, and a potential nuclear localization signal (Fig. 2A). According&lt;br /&gt;
to the classification of the WRKY superfamily (Eulgem et al. 2000), OsWRKY13 belongs to group II[2].&lt;br /&gt;
OsWRKY13 was overexpressed in cultivar Mudanjiang 8 (O.sativa subsp. japonica).&lt;br /&gt;
&lt;br /&gt;
===Function===&lt;br /&gt;
&lt;br /&gt;
Rice OsWRKY13 is a potentially important transcriptional regulator involved in multiple physiological processes. It mediates disease resistance to bacterial blight caused by Xanthomonas oryzae pv. oryzae (Xoo) and fungal blast caused by Magnaporthe grisea through activation of salicylic acid (SA)-dependent pathways and suppression of jasmonic acid (JA)-dependent pathways(FIG1); OsWRKY13 can bind to the W-box and W-box like cis-elements that are present in the promoters of some pathogen-induced defence-responsive genes [2,3]. Furthermore, genomewide analyses of the expression profiling of OsWRKY13-activated lines reveal that OsWRKY13 directly or indirectly regulates the expression of more than 500 genes [4].&lt;br /&gt;
&lt;br /&gt;
[[File:FiG1.png|300px|thumb|left|FIG1]]&lt;br /&gt;
&lt;br /&gt;
Fig. 1. Defense signaling model for the roles of OsWRKY13 in regulation of salicylic acid (SA)- and jasmonic acid (JA)-dependent pathways. Thick solid lines indicate direct action of OsWRKY13 has been confirmed by protein-DNA binding assays; thin solid lines, regulation may be executed by direct or indirect action; dotted lines, regulation has been confirmed in rice or other plant species; the line ending with arrow, activation; and the line ending with perpendicular short line indicates suppression.&lt;br /&gt;
&lt;br /&gt;
OsWRKY13 is also a potential regulator of other physiological processes during pathogen infection. It activates redox homeostasis by the glutathione/glutaredoxin system as well as the flavonoid biosynthesis pathway, which may enhance the biosynthesis of antimicrobial flavonoid phytoalexins [4]. OsWRKY13 inhibits the SNAC1-mediated abiotic stress defence pathway and terpenoid metabolism pathway to suppress salt and cold defence responses as well as to putatively retard rice growth and development[4]. Compared to the large number of differentially expressed genes in OsWRKY13-activated plants, however,most OsWRKY13-regulated pathways have yet to be elucidated.&lt;br /&gt;
To understand the transcriptional regulation of OsWRKY13, the types of transcription factors and conserved motifs in the promoter regions of the genes differentially expressed in OsWRKY13-activated plants were analyzed. The results suggest that the actions of OsWRKY13 on the expression of more than 500 genes are partitioned by different types of transcription factors through binding to distinctly distributed cis-acting elements in the promoters of OsWRKY13-upregulated and -downregulated genes. Furthermore, OsWRKY13 appears to bind preferentially to the promoters of downregulated genes in vitro, suggesting that it may function more as a negative transcriptional regulator[1].&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;Rice transcription regulator OsWRKY13 influences the functioning of more than 500 genes in multiple signalling pathways, with roles in disease resistance, redox homeostasis,abiotic stress responses, and development[1].&lt;br /&gt;
==Annotated Information==&lt;br /&gt;
&lt;br /&gt;
===Expression===&lt;br /&gt;
Comparative analysis of the genomic and cDNA sequences of OsWRKY13 (GenBank accession number EF143611) from resistant cultivar Minghui 63 (Oryza sativa subsp. indica) showed that the gene was 1,505 bp in length and had a coding region interrupted by two introns. The putative encoding product of OsWRKY13 consisted of 316 amino acids, which contained a WRKY motif, a zinc-finger motif, and a potential nuclear localization signal (Fig. 1A). According&lt;br /&gt;
to the classification of the WRKY superfamily (Eulgem et al. 2000), OsWRKY13 belongs to group II[2].&lt;br /&gt;
OsWRKY13 was overexpressed in cultivar Mudanjiang 8 (O.sativa subsp. japonica).&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===Function===&lt;br /&gt;
&lt;br /&gt;
Rice OsWRKY13 is a potentially important transcriptional regulator involved in multiple physiological processes. It mediates disease resistance to bacterial blight caused by Xanthomonas oryzae pv. oryzae (Xoo) and fungal blast caused by Magnaporthe grisea through activation of salicylic acid (SA)-dependent pathways and suppression of jasmonic acid (JA)-dependent pathways(FIG1); OsWRKY13 can bind to the W-box and W-box like cis-elements that are present in the promoters of some pathogen-induced defence-responsive genes [2,3]. Furthermore, genomewide analyses of the expression profiling of OsWRKY13-activated lines reveal that OsWRKY13 directly or indirectly regulates the expression of more than 500 genes [4].&lt;br /&gt;
[[File:FIG1]]&lt;br /&gt;
Fig. 1. Defense signaling model for the roles of OsWRKY13 in regulation of salicylic acid (SA)- and jasmonic acid (JA)-dependent pathways. Thick solid lines indicate direct action of OsWRKY13 has been confirmed by protein-DNA binding assays; thin solid lines, regulation may be executed by direct or indirect action; dotted lines, regulation has been confirmed in rice or other plant species; the line ending with arrow, activation; and the line ending with perpendicular short line indicates suppression.&lt;br /&gt;
&lt;br /&gt;
OsWRKY13 is also a potential regulator of other physiological processes during pathogen infection. It activates redox homeostasis by the glutathione/glutaredoxin system as well as the flavonoid biosynthesis pathway, which may enhance the biosynthesis of antimicrobial flavonoid phytoalexins [4]. OsWRKY13 inhibits the SNAC1-mediated abiotic stress defence pathway and terpenoid metabolism pathway to suppress salt and cold defence responses as well as to putatively retard rice growth and development[4]. Compared to the large number of differentially expressed genes in OsWRKY13-activated plants, however,most OsWRKY13-regulated pathways have yet to be elucidated.&lt;br /&gt;
To understand the transcriptional regulation of OsWRKY13, the types of transcription factors and conserved motifs in the promoter regions of the genes differentially expressed in OsWRKY13-activated plants were analyzed. The results suggest that the actions of OsWRKY13 on the expression of more than 500 genes are partitioned by different types of transcription factors through binding to distinctly distributed cis-acting elements in the promoters of OsWRKY13-upregulated and -downregulated genes. Furthermore, OsWRKY13 appears to bind preferentially to the promoters of downregulated genes in vitro, suggesting that it may function more as a negative transcriptional regulator[1].&lt;br /&gt;

OsRR6 is a kind of CK-inducible type-A response regulator in rice[2].&lt;br /&gt;
==Annotated Information==&lt;br /&gt;
===Function===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is a kind of CK-inducible type-A response regulator[2].The type-A response regulators are relatively small, containing a receiver domain along with short N- and C-terminal extensions. &lt;br /&gt;
&lt;br /&gt;
The expression of a majority of OsRR genes was not significantly altered under stress, with the notable exception of OsRR6. The expression of OsRR6 gene was induced to significant levels by salt, dehydration and low temperature treatments (Fig. 1), and results were reproducible. This indicates that OsRR6 may play an important role in abiotic stress signaling in rice, besides acting as a component in cytokinin signaling[1].&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
[[File:Fig1.png|300px|thumb|left|Fig.1]]&lt;br /&gt;
The induction of OsRR6 by different abiotic stress stimuli provides a molecular link between stress and cytokinin signaling as well[1].&lt;br /&gt;
&lt;br /&gt;
Overexpression of OsRR6 also affected the expression of CK-responsive genes[2].&lt;br /&gt;
&lt;br /&gt;
OsRR6-ox plants displayed altered morphologies and changes in CK metabolism, probably due to changes in the gene regulatory network[2].&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''Fig.1''': Changes in transcript levels of the OsRR6 gene in response to different stress treatments. The transcript levels of OsRR6 gene in 6-day-old light-grown seedlings treated with ABA, NaCl, mannitol and cold for 6 h, were plotted as the relative expression (fold) of the seedlings mock-treated for the same duration.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Generated transgenic rice plants that overexpress OsRR6 (OsRR6-ox) by fusing its coding sequence to the rice actin1 (Act1) promoter, because this promoter generally produces much higher levels of constitutive expression in rice than the cauliflower mosaic virus(CaMV) 35S promoter. Callus transformed with Act1::OsRR6 showed severe retardation of shoot regeneration compared with callus transformed with a control vector (Fig. 2)[2].&lt;br /&gt;
[[File:Fig2.png|300px|thumb|left|Fig.2]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''Fig.2''': OsRR6 represses shoot regeneration in rice callus. Callus was transformed with Agrobacterium carrying a binary vector pActnos/Hmz (Vec.), Act1::OsRR6 (OsRR6) or Act1::OsRR6D103E (OsRR6D103E). Calli were selected with hygromycin B and grown on regeneration agar plates for 6 weeks.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Moreover, each of 20 OsRR6D103E-ox independent lines was indistinguishable from plants transformed with a control vector (control plants; Fig. 3A, B). These results support the hypothesis that growth defects associated with OsRR6 overexpression are due to a requirement for phosphorylation of OsRR6[2].&lt;br /&gt;
[[File:Fig3.png|300px|thumb|left|Fig.3]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''Fig.3''': Morphologies of transgenic plants overexpressing OsRR6. OsRR6-ox transgenic plants (T0 generation) were grown on MS-agar plates containing hygromycin B for 7 d, and then hydroponically grown for 75 d. Transgenic plants, transformed with vector pActnos/Hmz (Vec.) or Act1::OsRR6D103E (OsRR6D103E-ox), were also grown under the same conditions. The typical phenotype of each transgenic line and their panicles are shown in (A) and (B). Total RNA samples were prepared from the shoots of each transgenic plant. (C) Semiquantitative RT–PCR analysis of the OsRR6 gene in the transgenic lines. OsAct1 is an extraction and loading control.&lt;br /&gt;
&lt;br /&gt;
Future analyses of knockout or RNA interference mutants of OsRR6 will enable us to define further its possible participation in stress responses.&lt;br /&gt;
&lt;br /&gt;
===Expression===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2  (Fig. 4)[4]. &lt;br /&gt;

'''Fig.4''':Locations and duplications of putative cytokinin two-component regulators in the rice chromosomes (cv. Nipponbare). Ovals on the chromosomes represent centromeres.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The OsRR genes express differentially in various organs examined, and also in response to light[1]. Most of the OsRR genes were expressed at relatively higher level in mature tissues (leaves and flowers).The majority of the type-A OsRR genes (OsRR2–9 and OsRR11) were expressed at various levels in roots, stems, leaves, and spikelets (Fig.5)([4]. OsRR6 was expressed mostly in roots and leaves.&lt;br /&gt;
&lt;br /&gt;
The transcript levels of OsRR2, 3, 4, 6, 7,and 9 were significantly higher in etiolated seedlings as compared to green seedlings (Fig. 6)[4].&lt;br /&gt;
[[File:Fig5.png|300px|thumb|right|Fig.5]]&lt;br /&gt;

RNA was isolated from roots and leaves from Nipponbare rice growing in liquid nutrient medium either with 1 μM 6-benzylaminopurine (6-BA) for 4 h or with no 6-BA. OsACTIN primers were used as a template control.&lt;br /&gt;

The relative mRNA levels of individual OsRR genes normalized with respect to housekeeping gene, UBQ5, in different tissues (GS, green seedlings; ES, etiolated seedlings; S, green shoots&lt;br /&gt;
&lt;br /&gt;
===Evolution===&lt;br /&gt;
&lt;br /&gt;
The type-A RRs are mainly composed of a receiver domain with short N- and C-terminal extensions [2], essentially similar to the E. coli response regulator (RR) CheY involved in chemotaxis, and lack a typical output domain(3). All the OsRR proteins also contain the highly conserved Lys and two Asp residues (D-D-K) in the receiver domain (Fig. 7B, C).However, OsRR6 and OsRR7 have N-terminal extensions rich in gly and asp residues (Fig. 7C). These N- and C-terminal variable regions may play a role in their localization to different cellular compartments.No homolog of OsRR6 was found within the duplicated region, suggesting the involvement of gene loss or more localized duplications[4].  &lt;br /&gt;

OsRR6 were found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2 that contains the OsRR11 gene [4](Fig. 4).&lt;br /&gt;

The expression of a majority of OsRR genes was not significantly altered under stress, with the notable exception of OsRR6. The expression of OsRR6 gene was induced to significant levels by salt, dehydration and low temperature treatments (Fig. 1), and results were reproducible. This indicates that OsRR6 may play an important role in abiotic stress signaling in rice, besides acting as a component in cytokinin signaling[1].&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
[[File:Fig1.png|300px|thumb|left|Fig.1]]&lt;br /&gt;
The induction of OsRR6 by different abiotic stress stimuli provides a molecular link between stress and cytokinin signaling as well[1].&lt;br /&gt;
&lt;br /&gt;
Overexpression of OsRR6 also affected the expression of CK-responsive genes[2].&lt;br /&gt;
&lt;br /&gt;
OsRR6-ox plants displayed altered morphologies and changes in CK metabolism, probably due to changes in the gene regulatory network[2].&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;

The transcript levels of OsRR6 gene in 6-day-old light-grown seedlings treated with ABA, NaCl, mannitol and cold for 6 h, were plotted as the relative expression (fold) of the seedlings mock-treated for the same duration.&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Generated transgenic rice plants that overexpress OsRR6 (OsRR6-ox) by fusing its coding sequence to the rice actin1 (Act1) promoter, because this promoter generally produces much higher levels of constitutive expression in rice than the cauliflower mosaic virus(CaMV) 35S promoter. Callus transformed with Act1::OsRR6 showed severe retardation of shoot regeneration compared with callus transformed with a control vector (Fig. 2)[2].&lt;br /&gt;

Callus was transformed with Agrobacterium carrying a binary vector pActnos/Hmz (Vec.), Act1::OsRR6 (OsRR6) or Act1::OsRR6D103E (OsRR6D103E). Calli were selected with hygromycin B and grown on regeneration agar plates for 6 weeks.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Moreover, each of 20 OsRR6D103E-ox independent lines was indistinguishable from plants transformed with a control vector (control plants; Fig. 3A, B). These results support the hypothesis that growth defects associated with OsRR6 overexpression are due to a requirement for phosphorylation of OsRR6[2].&lt;br /&gt;

&lt;br /&gt;
===Expression===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2  (Fig. 4)[4]. &lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
The OsRR genes express differentially in various organs examined, and also in response to light[1]. Most of the OsRR genes were expressed at relatively higher level in mature tissues (leaves and flowers).The majority of the type-A OsRR genes (OsRR2–9 and OsRR11) were expressed at various levels in roots, stems, leaves, and spikelets (Fig.5)([4]. OsRR6 was expressed mostly in roots and leaves.&lt;br /&gt;
&lt;br /&gt;
The transcript levels of OsRR2, 3, 4, 6, 7,and 9 were significantly higher in etiolated seedlings as compared to green seedlings (Fig. 6)[4].&lt;br /&gt;

&lt;br /&gt;
===Evolution===&lt;br /&gt;
&lt;br /&gt;
The type-A RRs are mainly composed of a receiver domain with short N- and C-terminal extensions [2], essentially similar to the E. coli response regulator (RR) CheY involved in chemotaxis, and lack a typical output domain(3). All the OsRR proteins also contain the highly conserved Lys and two Asp residues (D-D-K) in the receiver domain (Fig. 7B, C).However, OsRR6 and OsRR7 have N-terminal extensions rich in gly and asp residues (Fig. 7C). These N- and C-terminal variable regions may play a role in their localization to different cellular compartments.No homolog of OsRR6 was found within the duplicated region, suggesting the involvement of gene loss or more localized duplications[4].  &lt;br /&gt;

OsRR6 is a kind of CK-inducible type-A response regulator[2].The type-A response regulators are relatively small, containing a receiver domain along with short N- and C-terminal extensions. &lt;br /&gt;

The expression of OsRR6 gene was induced to significant levels by salt, dehydration and low temperature treatments (Fig. 1), and results were reproducible. This indicates that OsRR6 may play an important role in abiotic stress signaling in rice, besides acting as a component in cytokinin signaling[1].&lt;br /&gt;

OsRR6 is a kind of CK-inducible type-A response regulator in rice[2].&lt;br /&gt;
==Annotated Information==&lt;br /&gt;
===Function===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is a kind of CK-inducible type-A response regulator[2].The type-A response regulators are relatively small, containing a receiver domain along with short N- and C-terminal extensions. &lt;br /&gt;
&lt;br /&gt;
The expression of a majority of OsRR genes was not significantly altered under stress, with the notable exception of OsRR6. The expression of OsRR6 gene was induced to significant levels by salt, dehydration and low temperature treatments (Fig. 1), and results were reproducible. This indicates that OsRR6 may play an important role in abiotic stress signaling in rice, besides acting as a component in cytokinin signaling[1].&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
[[File:Fig1.png|300px|thumb|left|Fig.1]]&lt;br /&gt;
The induction of OsRR6 by different abiotic stress stimuli provides a molecular link between stress and cytokinin signaling as well[1].&lt;br /&gt;
&lt;br /&gt;
Overexpression of OsRR6 also affected the expression of CK-responsive genes[2].&lt;br /&gt;
&lt;br /&gt;
OsRR6-ox plants displayed altered morphologies and changes in CK metabolism, probably due to changes in the gene regulatory network[2].&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''Fig.1''': Changes in transcript levels of the OsRR6 gene in response to different stress treatments. The transcript levels of OsRR6 gene in 6-day-old light-grown seedlings treated with ABA, NaCl, mannitol and cold for 6 h, were plotted as the relative expression (fold) of the seedlings mock-treated for the same duration.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Generated transgenic rice plants that overexpress OsRR6 (OsRR6-ox) by fusing its coding sequence to the rice actin1 (Act1) promoter, because this promoter generally produces much higher levels of constitutive expression in rice than the cauliflower mosaic virus(CaMV) 35S promoter. Callus transformed with Act1::OsRR6 showed severe retardation of shoot regeneration compared with callus transformed with a control vector (Fig. 2)[2].&lt;br /&gt;
[[File:Fig2.png|300px|thumb|left|Fig.2]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''Fig.2''': OsRR6 represses shoot regeneration in rice callus. Callus was transformed with Agrobacterium carrying a binary vector pActnos/Hmz (Vec.), Act1::OsRR6 (OsRR6) or Act1::OsRR6D103E (OsRR6D103E). Calli were selected with hygromycin B and grown on regeneration agar plates for 6 weeks.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Moreover, each of 20 OsRR6D103E-ox independent lines was indistinguishable from plants transformed with a control vector (control plants; Fig. 3A, B). These results support the hypothesis that growth defects associated with OsRR6 overexpression are due to a requirement for phosphorylation of OsRR6[2].&lt;br /&gt;
[[File:Fig3.png|300px|thumb|left|Fig.3]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''Fig.3''': Morphologies of transgenic plants overexpressing OsRR6. OsRR6-ox transgenic plants (T0 generation) were grown on MS-agar plates containing hygromycin B for 7 d, and then hydroponically grown for 75 d. Transgenic plants, transformed with vector pActnos/Hmz (Vec.) or Act1::OsRR6D103E (OsRR6D103E-ox), were also grown under the same conditions. The typical phenotype of each transgenic line and their panicles are shown in (A) and (B). Total RNA samples were prepared from the shoots of each transgenic plant. (C) Semiquantitative RT–PCR analysis of the OsRR6 gene in the transgenic lines. OsAct1 is an extraction and loading control.&lt;br /&gt;
&lt;br /&gt;
Future analyses of knockout or RNA interference mutants of OsRR6 will enable us to define further its possible participation in stress responses.&lt;br /&gt;
&lt;br /&gt;
===Expression===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2  (Fig. 4)[4]. &lt;br /&gt;
&lt;br /&gt;

'''Fig.4''':Locations and duplications of putative cytokinin two-component regulators in the rice chromosomes (cv. Nipponbare). Ovals on the chromosomes represent centromeres.&lt;br /&gt;
&lt;br /&gt;
The OsRR genes express differentially in various organs examined, and also in response to light[1]. Most of the OsRR genes were expressed at relatively higher level in mature tissues (leaves and flowers).The majority of the type-A OsRR genes (OsRR2–9 and OsRR11) were expressed at various levels in roots, stems, leaves, and spikelets (Fig.5)([4]. OsRR6 was expressed mostly in roots and leaves.&lt;br /&gt;
&lt;br /&gt;
The transcript levels of OsRR2, 3, 4, 6, 7,and 9 were significantly higher in etiolated seedlings as compared to green seedlings (Fig. 6)[4].&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;

RNA was isolated from roots and leaves from Nipponbare rice growing in liquid nutrient medium either with 1 μM 6-benzylaminopurine (6-BA) for 4 h or with no 6-BA. OsACTIN primers were used as a template control.&lt;br /&gt;

The relative mRNA levels of individual OsRR genes normalized with respect to housekeeping gene, UBQ5, in different tissues (GS, green seedlings; ES, etiolated seedlings; S, green shoots&lt;br /&gt;
&lt;br /&gt;
===Evolution===&lt;br /&gt;
&lt;br /&gt;
The type-A RRs are mainly composed of a receiver domain with short N- and C-terminal extensions [2], essentially similar to the E. coli response regulator (RR) CheY involved in chemotaxis, and lack a typical output domain(3). All the OsRR proteins also contain the highly conserved Lys and two Asp residues (D-D-K) in the receiver domain (Fig. 7B, C).However, OsRR6 and OsRR7 have N-terminal extensions rich in gly and asp residues (Fig. 7C). These N- and C-terminal variable regions may play a role in their localization to different cellular compartments.No homolog of OsRR6 was found within the duplicated region, suggesting the involvement of gene loss or more localized duplications[4].  &lt;br /&gt;

The black vertical bars represent intron position. The numbers 0, 1 and 2 above the vertical bars represent the phase 0, 1 and 2 introns, respectively. (C) Multiple alignments of the OsRR proteins obtained with ClustalX. Fully and partially conserved (present in more than 50% of aligned sequences) residues are highlighted in black and gray boxes, respectively. Gaps (marked with dashes) have been introduced to maximize the alignments. The conserved receiver domain has been underlined. Conserved Asp and Lys residues are marked with asterisks. &lt;br /&gt;

OsRR6 were found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2 that contains the OsRR11 gene [4](Fig. 4).&lt;br /&gt;

The OsRR genes express differentially in various organs examined, and also in response to light[1]. Most of the OsRR genes were expressed at relatively higher level in mature tissues (leaves and flowers).The majority of the type-A OsRR genes (OsRR2–9 and OsRR11) were expressed at various levels in roots, stems, leaves, and spikelets (Fig.5)([4]. OsRR6 was expressed mostly in roots and leaves.&lt;br /&gt;
&lt;br /&gt;
The transcript levels of OsRR2, 3, 4, 6, 7,and 9 were significantly higher in etiolated seedlings as compared to green seedlings (Fig. 6)[4].&lt;br /&gt;

The type-A RRs are mainly composed of a receiver domain with short N- and C-terminal extensions [2], essentially similar to the E. coli response regulator (RR) CheY involved in chemotaxis, and lack a typical output domain(3). All the OsRR proteins also contain the highly conserved Lys and two Asp residues (D-D-K) in the receiver domain (Fig. 7B, C).However, OsRR6 and OsRR7 have N-terminal extensions rich in gly and asp residues (Fig. 7C). These N- and C-terminal variable regions may play a role in their localization to different cellular compartments.No homolog of OsRR6 was found within the duplicated region, suggesting the involvement of gene loss or more localized duplications[4].  &lt;br /&gt;

OsRR6 is a kind of CK-inducible type-A response regulator in rice[2].&lt;br /&gt;
==Annotated Information==&lt;br /&gt;
===Function===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is a kind of CK-inducible type-A response regulator[2].The type-A response regulators are relatively small, containing a receiver domain along with short N- and C-terminal extensions. &lt;br /&gt;
&lt;br /&gt;
The expression of a majority of OsRR genes was not significantly altered under stress, with the notable exception of OsRR6. The expression of OsRR6 gene was induced to significant levels by salt, dehydration and low temperature treatments (Fig. 1), and results were reproducible. This indicates that OsRR6 may play an important role in abiotic stress signaling in rice, besides acting as a component in cytokinin signaling[1].&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
[[File:Fig1.png|300px|thumb|left|Fig.1]]&lt;br /&gt;
The induction of OsRR6 by different abiotic stress stimuli provides a molecular link between stress and cytokinin signaling as well[1].&lt;br /&gt;
&lt;br /&gt;
Overexpression of OsRR6 also affected the expression of CK-responsive genes[2].&lt;br /&gt;
&lt;br /&gt;
OsRR6-ox plants displayed altered morphologies and changes in CK metabolism, probably due to changes in the gene regulatory network[2].&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''Fig.1''': Changes in transcript levels of the OsRR6 gene in response to different stress treatments. The transcript levels of OsRR6 gene in 6-day-old light-grown seedlings treated with ABA, NaCl, mannitol and cold for 6 h, were plotted as the relative expression (fold) of the seedlings mock-treated for the same duration.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Generated transgenic rice plants that overexpress OsRR6 (OsRR6-ox) by fusing its coding sequence to the rice actin1 (Act1) promoter, because this promoter generally produces much higher levels of constitutive expression in rice than the cauliflower mosaic virus(CaMV) 35S promoter. Callus transformed with Act1::OsRR6 showed severe retardation of shoot regeneration compared with callus transformed with a control vector (Fig. 2)[2].&lt;br /&gt;
[[File:Fig2.png|300px|thumb|left|Fig.2]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;

Callus was transformed with Agrobacterium carrying a binary vector pActnos/Hmz (Vec.), Act1::OsRR6 (OsRR6) or Act1::OsRR6D103E (OsRR6D103E). Calli were selected with hygromycin B and grown on regeneration agar plates for 6 weeks.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;

These results support the hypothesis that growth defects associated with OsRR6 overexpression are due to a requirement for phosphorylation of OsRR6[2].&lt;br /&gt;

OsRR6 is found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2  (Fig. 4)[4]. &lt;br /&gt;

OsRR6 is a kind of CK-inducible type-A response regulator in rice[2].&lt;br /&gt;
==Annotated Information==&lt;br /&gt;
===Function===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is a kind of CK-inducible type-A response regulator[2].The type-A response regulators are relatively small, containing a receiver domain along with short N- and C-terminal extensions. &lt;br /&gt;
&lt;br /&gt;
The expression of a majority of OsRR genes was not significantly altered under stress, with the notable exception of OsRR6. The expression of OsRR6 gene was induced to significant levels by salt, dehydration and low temperature treatments (Fig. 1), and results were reproducible. This indicates that OsRR6 may play an important role in abiotic stress signaling in rice, besides acting as a component in cytokinin signaling[1].&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
[[File:Fig1.png|300px|thumb|left|Fig.1]]&lt;br /&gt;
The induction of OsRR6 by different abiotic stress stimuli provides a molecular link between stress and cytokinin signaling as well[1].&lt;br /&gt;
&lt;br /&gt;
Overexpression of OsRR6 also affected the expression of CK-responsive genes[2].&lt;br /&gt;
&lt;br /&gt;
OsRR6-ox plants displayed altered morphologies and changes in CK metabolism, probably due to changes in the gene regulatory network[2].&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''Fig.1''': Changes in transcript levels of the OsRR6 gene in response to different stress treatments. The transcript levels of OsRR6 gene in 6-day-old light-grown seedlings treated with ABA, NaCl, mannitol and cold for 6 h, were plotted as the relative expression (fold) of the seedlings mock-treated for the same duration.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Generated transgenic rice plants that overexpress OsRR6 (OsRR6-ox) by fusing its coding sequence to the rice actin1 (Act1) promoter, because this promoter generally produces much higher levels of constitutive expression in rice than the cauliflower mosaic virus(CaMV) 35S promoter. Callus transformed with Act1::OsRR6 showed severe retardation of shoot regeneration compared with callus transformed with a control vector (Fig. 2)[2].&lt;br /&gt;
[[File:Fig2.png|300px|thumb|left|Fig.2]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''Fig.2''': OsRR6 represses shoot regeneration in rice callus. Callus was transformed with Agrobacterium carrying a binary vector pActnos/Hmz (Vec.), Act1::OsRR6 (OsRR6) or Act1::OsRR6D103E (OsRR6D103E). Calli were selected with hygromycin B and grown on regeneration agar plates for 6 weeks.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Moreover, each of 20 OsRR6D103E-ox independent lines was indistinguishable from plants transformed with a control vector (control plants; Fig. 3A, B). These results support the hypothesis that growth defects associated with OsRR6 overexpression are due to a requirement for phosphorylation of OsRR6[2].&lt;br /&gt;

'''Fig.3''': Morphologies of transgenic plants overexpressing OsRR6. OsRR6-ox transgenic plants (T0 generation) were grown on MS-agar plates containing hygromycin B for 7 d, and then hydroponically grown for 75 d. Transgenic plants, transformed with vector pActnos/Hmz (Vec.) or Act1::OsRR6D103E (OsRR6D103E-ox), were also grown under the same conditions. The typical phenotype of each transgenic line and their panicles are shown in (A) and (B). Total RNA samples were prepared from the shoots of each transgenic plant. (C) Semiquantitative RT–PCR analysis of the OsRR6 gene in the transgenic lines. OsAct1 is an extraction and loading control.&lt;br /&gt;
&lt;br /&gt;
Future analyses of knockout or RNA interference mutants of OsRR6 will enable us to define further its possible participation in stress responses.&lt;br /&gt;
&lt;br /&gt;
===Expression===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2  (Fig. 4)[4]. &lt;br /&gt;
&lt;br /&gt;

'''Fig.4''':Locations and duplications of putative cytokinin two-component regulators in the rice chromosomes (cv. Nipponbare). Ovals on the chromosomes represent centromeres.&lt;br /&gt;
&lt;br /&gt;
The OsRR genes express differentially in various organs examined, and also in response to light[1]. Most of the OsRR genes were expressed at relatively higher level in mature tissues (leaves and flowers).The majority of the type-A OsRR genes (OsRR2–9 and OsRR11) were expressed at various levels in roots, stems, leaves, and spikelets (Fig.5)([4]. OsRR6 was expressed mostly in roots and leaves.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The transcript levels of OsRR2, 3, 4, 6, 7,and 9 were significantly higher in etiolated seedlings as compared to green seedlings (Fig. 6)[4].&lt;br /&gt;
&lt;br /&gt;

RNA was isolated from roots and leaves from Nipponbare rice growing in liquid nutrient medium either with 1 μM 6-benzylaminopurine (6-BA) for 4 h or with no 6-BA. OsACTIN primers were used as a template control.&lt;br /&gt;
&lt;br /&gt;

The relative mRNA levels of individual OsRR genes normalized with respect to housekeeping gene, UBQ5, in different tissues (GS, green seedlings; ES, etiolated seedlings; S, green shoots&lt;br /&gt;
&lt;br /&gt;
===Evolution===&lt;br /&gt;
&lt;br /&gt;
The type-A RRs are mainly composed of a receiver domain with short N- and C-terminal extensions [2], essentially similar to the E. coli response regulator (RR) CheY involved in chemotaxis, and lack a typical output domain(3). All the OsRR proteins also contain the highly conserved Lys and two Asp residues (D-D-K) in the receiver domain (Fig. 7B, C).However, OsRR6 and OsRR7 have N-terminal extensions rich in gly and asp residues (Fig. 7C). These N- and C-terminal variable regions may play a role in their localization to different cellular compartments.No homolog of OsRR6 was found within the duplicated region, suggesting the involvement of gene loss or more localized duplications[4].  &lt;br /&gt;
&lt;br /&gt;

OsRR6 were found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2 that contains the OsRR11 gene [4](Fig. 4).&lt;br /&gt;

Most of the OsRR genes were expressed at relatively higher level in mature tissues (leaves and flowers).The majority of the type-A OsRR genes (OsRR2–9 and OsRR11) were expressed at various levels in roots, stems, leaves, and spikelets (Fig.5)([4]. OsRR6 was expressed mostly in roots and leaves.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The transcript levels of OsRR2, 3, 4, 6, 7,and 9 were significantly higher in etiolated seedlings as compared to green seedlings (Fig. 6)[4].&lt;br /&gt;

&lt;br /&gt;
The type-A RRs are mainly composed of a receiver domain with short N- and C-terminal extensions [2], essentially similar to the E. coli response regulator (RR) CheY involved in chemotaxis, and lack a typical output domain(3). All the OsRR proteins also contain the highly conserved Lys and two Asp residues (D-D-K) in the receiver domain (Fig. 7B, C).However, OsRR6 and OsRR7 have N-terminal extensions rich in gly and asp residues (Fig. 7C). These N- and C-terminal variable regions may play a role in their localization to different cellular compartments.No homolog of OsRR6 was found within the duplicated region, suggesting the involvement of gene loss or more localized duplications[4].  &lt;br /&gt;

OsRR6 is a kind of CK-inducible type-A response regulator in rice[2].&lt;br /&gt;
==Annotated Information==&lt;br /&gt;
===Function===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is a kind of CK-inducible type-A response regulator[2].The type-A response regulators are relatively small, containing a receiver domain along with short N- and C-terminal extensions. &lt;br /&gt;
&lt;br /&gt;
The expression of a majority of OsRR genes was not significantly altered under stress, with the notable exception of OsRR6. The expression of OsRR6 gene was induced to significant levels by salt, dehydration and low temperature treatments (Fig. 1), and results were reproducible. This indicates that OsRR6 may play an important role in abiotic stress signaling in rice, besides acting as a component in cytokinin signaling[1].&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
[[File:Fig1.png|300px|thumb|left|Fig.1]]&lt;br /&gt;
The induction of OsRR6 by different abiotic stress stimuli provides a molecular link between stress and cytokinin signaling as well[1].&lt;br /&gt;
&lt;br /&gt;
Overexpression of OsRR6 also affected the expression of CK-responsive genes[2].&lt;br /&gt;
&lt;br /&gt;
OsRR6-ox plants displayed altered morphologies and changes in CK metabolism, probably due to changes in the gene regulatory network[2].&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''Fig.1''': Changes in transcript levels of the OsRR6 gene in response to different stress treatments. The transcript levels of OsRR6 gene in 6-day-old light-grown seedlings treated with ABA, NaCl, mannitol and cold for 6 h, were plotted as the relative expression (fold) of the seedlings mock-treated for the same duration.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Generated transgenic rice plants that overexpress OsRR6 (OsRR6-ox) by fusing its coding sequence to the rice actin1 (Act1) promoter, because this promoter generally produces much higher levels of constitutive expression in rice than the cauliflower mosaic virus(CaMV) 35S promoter. Callus transformed with Act1::OsRR6 showed severe retardation of shoot regeneration compared with callus transformed with a control vector (Fig. 2)[2].&lt;br /&gt;
[[File:Fig2.png|300px|thumb|left|Fig.2]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''Fig.2''': OsRR6 represses shoot regeneration in rice callus. Callus was transformed with Agrobacterium carrying a binary vector pActnos/Hmz (Vec.), Act1::OsRR6 (OsRR6) or Act1::OsRR6D103E (OsRR6D103E). Calli were selected with hygromycin B and grown on regeneration agar plates for 6 weeks.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Moreover, each of 20 OsRR6D103E-ox independent lines was indistinguishable from plants transformed with a control vector (control plants; Fig. 3A, B). These results support the hypothesis that growth defects associated with OsRR6 overexpression are due to a requirement for phosphorylation of OsRR6[2].&lt;br /&gt;
[[File:Fig3.png|300px|thumb|left|Fig.3]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''Fig.3''': Morphologies of transgenic plants overexpressing OsRR6. OsRR6-ox transgenic plants (T0 generation) were grown on MS-agar plates containing hygromycin B for 7 d, and then hydroponically grown for 75 d. Transgenic plants, transformed with vector pActnos/Hmz (Vec.) or Act1::OsRR6D103E (OsRR6D103E-ox), were also grown under the same conditions. The typical phenotype of each transgenic line and their panicles are shown in (A) and (B). Total RNA samples were prepared from the shoots of each transgenic plant. (C) Semiquantitative RT–PCR analysis of the OsRR6 gene in the transgenic lines. OsAct1 is an extraction and loading control.&lt;br /&gt;
&lt;br /&gt;
Future analyses of knockout or RNA interference mutants of OsRR6 will enable us to define further its possible participation in stress responses.&lt;br /&gt;
&lt;br /&gt;
===Expression===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2  (Fig. 4)[4]. &lt;br /&gt;
&lt;br /&gt;

Most of the OsRR genes were expressed at relatively higher level in mature tissues (leaves and flowers).The majority of the type-A OsRR genes (OsRR2–9 and OsRR11) were expressed at various levels in roots, stems, leaves, and spikelets (Fig.5)([4].

OsRR6 is a kind of CK-inducible type-A response regulator in rice[2].&lt;br /&gt;
==Annotated Information==&lt;br /&gt;
===Function===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is a kind of CK-inducible type-A response regulator[2].The type-A response regulators are relatively small, containing a receiver domain along with short N- and C-terminal extensions. &lt;br /&gt;
&lt;br /&gt;
The expression of a majority of OsRR genes was not significantly altered under stress, with the notable exception of OsRR6. The expression of OsRR6 gene was induced to significant levels by salt, dehydration and low temperature treatments (Fig. 1), and results were reproducible. This indicates that OsRR6 may play an important role in abiotic stress signaling in rice, besides acting as a component in cytokinin signaling[1].&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
[[File:Fig1.png|300px|thumb|left|Fig.1]]&lt;br /&gt;
The induction of OsRR6 by different abiotic stress stimuli provides a molecular link between stress and cytokinin signaling as well[1].&lt;br /&gt;
&lt;br /&gt;
Overexpression of OsRR6 also affected the expression of CK-responsive genes[2].&lt;br /&gt;
&lt;br /&gt;
OsRR6-ox plants displayed altered morphologies and changes in CK metabolism, probably due to changes in the gene regulatory network[2].&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''Fig.1''': Changes in transcript levels of the OsRR6 gene in response to different stress treatments. The transcript levels of OsRR6 gene in 6-day-old light-grown seedlings treated with ABA, NaCl, mannitol and cold for 6 h, were plotted as the relative expression (fold) of the seedlings mock-treated for the same duration.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Generated transgenic rice plants that overexpress OsRR6 (OsRR6-ox) by fusing its coding sequence to the rice actin1 (Act1) promoter, because this promoter generally produces much higher levels of constitutive expression in rice than the cauliflower mosaic virus(CaMV) 35S promoter. Callus transformed with Act1::OsRR6 showed severe retardation of shoot regeneration compared with callus transformed with a control vector (Fig. 2)[2].&lt;br /&gt;
[[File:Fig2.png|300px|thumb|left|Fig.2]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''Fig.2''': OsRR6 represses shoot regeneration in rice callus. Callus was transformed with Agrobacterium carrying a binary vector pActnos/Hmz (Vec.), Act1::OsRR6 (OsRR6) or Act1::OsRR6D103E (OsRR6D103E). Calli were selected with hygromycin B and grown on regeneration agar plates for 6 weeks.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Moreover, each of 20 OsRR6D103E-ox independent lines was indistinguishable from plants transformed with a control vector (control plants; Fig. 3A, B). These results support the hypothesis that growth defects associated with OsRR6 overexpression are due to a requirement for phosphorylation of OsRR6[2].&lt;br /&gt;
[[File:Fig3.png|300px|thumb|left|Fig.3]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''Fig.3''': Morphologies of transgenic plants overexpressing OsRR6. OsRR6-ox transgenic plants (T0 generation) were grown on MS-agar plates containing hygromycin B for 7 d, and then hydroponically grown for 75 d. Transgenic plants, transformed with vector pActnos/Hmz (Vec.) or Act1::OsRR6D103E (OsRR6D103E-ox), were also grown under the same conditions. The typical phenotype of each transgenic line and their panicles are shown in (A) and (B). Total RNA samples were prepared from the shoots of each transgenic plant. (C) Semiquantitative RT–PCR analysis of the OsRR6 gene in the transgenic lines. OsAct1 is an extraction and loading control.&lt;br /&gt;
&lt;br /&gt;
Future analyses of knockout or RNA interference mutants of OsRR6 will enable us to define further its possible participation in stress responses.&lt;br /&gt;
&lt;br /&gt;
===Expression===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2  (Fig. 4)[4]. &lt;br /&gt;
[[File:Fig4.png|200px|thumb|right|Fig.4:Locations and duplications of putative cytokinin two-component regulators in the rice chromosomes (cv. Nipponbare). Ovals on the chromosomes represent centromeres.]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The OsRR genes express differentially in various organs examined, and also in response to light[1]. Most of the OsRR genes were expressed at relatively higher level in mature tissues (leaves and flowers).The majority of the type-A OsRR genes (OsRR2–9 and OsRR11) were expressed at various levels in roots, stems, leaves, and spikelets (Fig.5)([4]. OsRR6 was expressed mostly in roots and leaves.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The transcript levels of OsRR2, 3, 4, 6, 7,and 9 were significantly higher in etiolated seedlings as compared to green seedlings (Fig. 6)[4].&lt;br /&gt;
[[File:Fig5.png|200px|thumb|right|Fig.5:The analysis of the response of the system genes family to cytokinin by RT-PCR. RNA was isolated from roots and leaves from Nipponbare rice growing in liquid nutrient medium either with 1 μM 6-benzylaminopurine (6-BA) for 4 h or with no 6-BA. OsACTIN primers were used as a template control.]]&lt;br /&gt;

&lt;br /&gt;

The relative mRNA levels of individual OsRR genes normalized with respect to housekeeping gene, UBQ5, in different tissues (GS, green seedlings; ES, etiolated seedlings; S, green shoots]]&lt;br /&gt;
&lt;br /&gt;
===Evolution===&lt;br /&gt;
&lt;br /&gt;
The type-A RRs are mainly composed of a receiver domain with short N- and C-terminal extensions [2], essentially similar to the E. coli response regulator (RR) CheY involved in chemotaxis, and lack a typical output domain(3). All the OsRR proteins also contain the highly conserved Lys and two Asp residues (D-D-K) in the receiver domain (Fig. 7B, C).However, OsRR6 and OsRR7 have N-terminal extensions rich in gly and asp residues (Fig. 7C). These N- and C-terminal variable regions may play a role in their localization to different cellular compartments.No homolog of OsRR6 was found within the duplicated region, suggesting the involvement of gene loss or more localized duplications[4].  &lt;br /&gt;
&lt;br /&gt;

OsRR6 were found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2 that contains the OsRR11 gene [4](Fig. 4).&lt;br /&gt;

&lt;br /&gt;
===Expression===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2  (Fig. 4)[4]. &lt;br /&gt;

&lt;br /&gt;

===Evolution===&lt;br /&gt;
&lt;br /&gt;
The type-A RRs are mainly composed of a receiver domain with short N- and C-terminal extensions [2], essentially similar to the E. coli response regulator (RR) CheY involved in chemotaxis, and lack a typical output domain(3). All the OsRR proteins also contain the highly conserved Lys and two Asp residues (D-D-K) in the receiver domain (Fig. 7B, C).However, OsRR6 and OsRR7 have N-terminal extensions rich in gly and asp residues (Fig. 7C). These N- and C-terminal variable regions may play a role in their localization to different cellular compartments.No homolog of OsRR6 was found within the duplicated region, suggesting the involvement of gene loss or more localized duplications[4].  &lt;br /&gt;

OsRR6 is a kind of CK-inducible type-A response regulator in rice[2].&lt;br /&gt;
==Annotated Information==&lt;br /&gt;
===Function===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is a kind of CK-inducible type-A response regulator[2].The type-A response regulators are relatively small, containing a receiver domain along with short N- and C-terminal extensions. &lt;br /&gt;
&lt;br /&gt;
The expression of a majority of OsRR genes was not significantly altered under stress, with the notable exception of OsRR6. The expression of OsRR6 gene was induced to significant levels by salt, dehydration and low temperature treatments (Fig. 1), and results were reproducible. This indicates that OsRR6 may play an important role in abiotic stress signaling in rice, besides acting as a component in cytokinin signaling[1].&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
[[File:Fig1.png|300px|thumb|left|Fig.1]]&lt;br /&gt;
The induction of OsRR6 by different abiotic stress stimuli provides a molecular link between stress and cytokinin signaling as well[1].&lt;br /&gt;
&lt;br /&gt;
Overexpression of OsRR6 also affected the expression of CK-responsive genes[2].&lt;br /&gt;
&lt;br /&gt;
OsRR6-ox plants displayed altered morphologies and changes in CK metabolism, probably due to changes in the gene regulatory network[2].&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''Fig.1''': Changes in transcript levels of the OsRR6 gene in response to different stress treatments. The transcript levels of OsRR6 gene in 6-day-old light-grown seedlings treated with ABA, NaCl, mannitol and cold for 6 h, were plotted as the relative expression (fold) of the seedlings mock-treated for the same duration.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Generated transgenic rice plants that overexpress OsRR6 (OsRR6-ox) by fusing its coding sequence to the rice actin1 (Act1) promoter, because this promoter generally produces much higher levels of constitutive expression in rice than the cauliflower mosaic virus(CaMV) 35S promoter. Callus transformed with Act1::OsRR6 showed severe retardation of shoot regeneration compared with callus transformed with a control vector (Fig. 2)[2].&lt;br /&gt;
[[File:Fig2.png|300px|thumb|left|Fig.2]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''Fig.2''': OsRR6 represses shoot regeneration in rice callus. Callus was transformed with Agrobacterium carrying a binary vector pActnos/Hmz (Vec.), Act1::OsRR6 (OsRR6) or Act1::OsRR6D103E (OsRR6D103E). Calli were selected with hygromycin B and grown on regeneration agar plates for 6 weeks.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Moreover, each of 20 OsRR6D103E-ox independent lines was indistinguishable from plants transformed with a control vector (control plants; Fig. 3A, B). These results support the hypothesis that growth defects associated with OsRR6 overexpression are due to a requirement for phosphorylation of OsRR6[2].&lt;br /&gt;
[[File:Fig3.png|300px|thumb|left|Fig.3: Morphologies of transgenic plants overexpressing OsRR6. OsRR6-ox transgenic plants (T0 generation) were grown on MS-agar plates containing hygromycin B for 7 d, and then hydroponically grown for 75 d. Transgenic plants, transformed with vector pActnos/Hmz (Vec.) or Act1::OsRR6D103E (OsRR6D103E-ox), were also grown under the same conditions. The typical phenotype of each transgenic line and their panicles are shown in (A) and (B). Total RNA samples were prepared from the shoots of each transgenic plant. (C) Semiquantitative RT–PCR analysis of the OsRR6 gene in the transgenic lines. OsAct1 is an extraction and loading control.]]&lt;br /&gt;
&lt;br /&gt;
Future analyses of knockout or RNA interference mutants of OsRR6 will enable us to define further its possible participation in stress responses.&lt;br /&gt;
&lt;br /&gt;
===Expression===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2  (Fig. 4)[4]. &lt;br /&gt;
[[File:Fig4.png|200px|thumb|right|Fig.4:Locations and duplications of putative cytokinin two-component regulators in the rice chromosomes (cv. Nipponbare). Ovals on the chromosomes represent centromeres.]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The OsRR genes express differentially in various organs examined, and also in response to light[1]. Most of the OsRR genes were expressed at relatively higher level in mature tissues (leaves and flowers).The majority of the type-A OsRR genes (OsRR2–9 and OsRR11) were expressed at various levels in roots, stems, leaves, and spikelets (Fig.5)([4]. OsRR6 was expressed mostly in roots and leaves.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The transcript levels of OsRR2, 3, 4, 6, 7,and 9 were significantly higher in etiolated seedlings as compared to green seedlings (Fig. 6)[4].&lt;br /&gt;
[[File:Fig5.png|200px|thumb|right|Fig.5:The analysis of the response of the system genes family to cytokinin by RT-PCR.

OsRR6 is a kind of CK-inducible type-A response regulator in rice[2].&lt;br /&gt;
==Annotated Information==&lt;br /&gt;
===Function===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is a kind of CK-inducible type-A response regulator[2].The type-A response regulators are relatively small, containing a receiver domain along with short N- and C-terminal extensions. &lt;br /&gt;
&lt;br /&gt;
The expression of a majority of OsRR genes was not significantly altered under stress, with the notable exception of OsRR6. The expression of OsRR6 gene was induced to significant levels by salt, dehydration and low temperature treatments (Fig. 1), and results were reproducible. This indicates that OsRR6 may play an important role in abiotic stress signaling in rice, besides acting as a component in cytokinin signaling[1].&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
[[File:Fig1.png|300px|thumb|left|Fig.1]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''Fig.1''': Changes in transcript levels of the OsRR6 gene in response to different stress treatments. The transcript levels of OsRR6 gene in 6-day-old light-grown seedlings treated with ABA, NaCl, mannitol and cold for 6 h, were plotted as the relative expression (fold) of the seedlings mock-treated for the same duration.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The induction of OsRR6 by different abiotic stress stimuli provides a molecular link between stress and cytokinin signaling as well[1].&lt;br /&gt;
&lt;br /&gt;
Overexpression of OsRR6 also affected the expression of CK-responsive genes[2].&lt;br /&gt;
&lt;br /&gt;
OsRR6-ox plants displayed altered morphologies and changes in CK metabolism, probably due to changes in the gene regulatory network[2].&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Generated transgenic rice plants that overexpress OsRR6 (OsRR6-ox) by fusing its coding sequence to the rice actin1 (Act1) promoter, because this promoter generally produces much higher levels of constitutive expression in rice than the cauliflower mosaic virus(CaMV) 35S promoter. Callus transformed with Act1::OsRR6 showed severe retardation of shoot regeneration compared with callus transformed with a control vector (Fig. 2)[2].&lt;br /&gt;
[[File:Fig2.png|300px|thumb|left|Fig.2]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''Fig.2''': OsRR6 represses shoot regeneration in rice callus. Callus was transformed with Agrobacterium carrying a binary vector pActnos/Hmz (Vec.), Act1::OsRR6 (OsRR6) or Act1::OsRR6D103E (OsRR6D103E). Calli were selected with hygromycin B and grown on regeneration agar plates for 6 weeks.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Moreover, each of 20 OsRR6D103E-ox independent lines was indistinguishable from plants transformed with a control vector (control plants; Fig. 3A, B). These results support the hypothesis that growth defects associated with OsRR6 overexpression are due to a requirement for phosphorylation of OsRR6[2].&lt;br /&gt;
[[File:Fig3.png|300px|thumb|left|Fig.3: Morphologies of transgenic plants overexpressing OsRR6. OsRR6-ox transgenic plants (T0 generation) were grown on MS-agar plates containing hygromycin B for 7 d, and then hydroponically grown for 75 d. Transgenic plants, transformed with vector pActnos/Hmz (Vec.) or Act1::OsRR6D103E (OsRR6D103E-ox), were also grown under the same conditions. The typical phenotype of each transgenic line and their panicles are shown in (A) and (B). Total RNA samples were prepared from the shoots of each transgenic plant. (C) Semiquantitative RT–PCR analysis of the OsRR6 gene in the transgenic lines. OsAct1 is an extraction and loading control.]]&lt;br /&gt;
&lt;br /&gt;
Future analyses of knockout or RNA interference mutants of OsRR6 will enable us to define further its possible participation in stress responses.&lt;br /&gt;
&lt;br /&gt;
===Expression===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2  (Fig. 4)[4]. &lt;br /&gt;
[[File:Fig4.png|200px|thumb|right|Fig.4:Locations and duplications of putative cytokinin two-component regulators in the rice chromosomes (cv. Nipponbare). Ovals on the chromosomes represent centromeres.]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The OsRR genes express differentially in various organs examined, and also in response to light[1]. Most of the OsRR genes were expressed at relatively higher level in mature tissues (leaves and flowers).The majority of the type-A OsRR genes (OsRR2–9 and OsRR11) were expressed at various levels in roots, stems, leaves, and spikelets (Fig.5)([4]. OsRR6 was expressed mostly in roots and leaves.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The transcript levels of OsRR2, 3, 4, 6, 7,and 9 were significantly higher in etiolated seedlings as compared to green seedlings (Fig. 6)[4].&lt;br /&gt;
[[File:Fig5.png|200px|thumb|right|Fig.5:The analysis of the response of the system genes family to cytokinin by RT-PCR. RNA was isolated from roots and leaves from Nipponbare rice growing in liquid nutrient medium either with 1 μM 6-benzylaminopurine (6-BA) for 4 h or with no 6-BA. OsACTIN primers were used as a template control.]]&lt;br /&gt;

&lt;br /&gt;

The relative mRNA levels of individual OsRR genes normalized with respect to housekeeping gene, UBQ5, in different tissues (GS, green seedlings; ES, etiolated seedlings; S, green shoots]]&lt;br /&gt;
&lt;br /&gt;
===Evolution===&lt;br /&gt;
&lt;br /&gt;
The type-A RRs are mainly composed of a receiver domain with short N- and C-terminal extensions [2], essentially similar to the E. coli response regulator (RR) CheY involved in chemotaxis, and lack a typical output domain(3). All the OsRR proteins also contain the highly conserved Lys and two Asp residues (D-D-K) in the receiver domain (Fig. 7B, C).However, OsRR6 and OsRR7 have N-terminal extensions rich in gly and asp residues (Fig. 7C). These N- and C-terminal variable regions may play a role in their localization to different cellular compartments.No homolog of OsRR6 was found within the duplicated region, suggesting the involvement of gene loss or more localized duplications[4].  &lt;br /&gt;
&lt;br /&gt;

OsRR6 were found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2 that contains the OsRR11 gene [4](Fig. 4).&lt;br /&gt;

OsRR6 is a kind of CK-inducible type-A response regulator in rice[2].&lt;br /&gt;
==Annotated Information==&lt;br /&gt;
===Function===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is a kind of CK-inducible type-A response regulator[2].The type-A response regulators are relatively small, containing a receiver domain along with short N- and C-terminal extensions. &lt;br /&gt;
&lt;br /&gt;
The expression of a majority of OsRR genes was not significantly altered under stress, with the notable exception of OsRR6. The expression of OsRR6 gene was induced to significant levels by salt, dehydration and low temperature treatments (Fig. 1), and results were reproducible. This indicates that OsRR6 may play an important role in abiotic stress signaling in rice, besides acting as a component in cytokinin signaling[1].&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
Fig.1: Changes in transcript levels of the OsRR6 gene in response to different stress treatments. The transcript levels of OsRR6 gene in 6-day-old light-grown seedlings treated with ABA, NaCl, mannitol and cold for 6 h, were plotted as the relative expression (fold) of the seedlings mock-treated for the same duration.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The induction of OsRR6 by different abiotic stress stimuli provides a molecular link between stress and cytokinin signaling as well[1].&lt;br /&gt;
&lt;br /&gt;
Overexpression of OsRR6 also affected the expression of CK-responsive genes[2].&lt;br /&gt;
&lt;br /&gt;
OsRR6-ox plants displayed altered morphologies and changes in CK metabolism, probably due to changes in the gene regulatory network[2].&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Moreover, each of 20 OsRR6D103E-ox independent lines was indistinguishable from plants transformed with a control vector (control plants; Fig. 3A, B). These results support the hypothesis that growth defects associated with OsRR6 overexpression are due to a requirement for phosphorylation of OsRR6[2].&lt;br /&gt;

&lt;br /&gt;
===Expression===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2  (Fig. 4)[4]. &lt;br /&gt;
[[File:Fig4.png|200px|thumb|right|Fig.4:Locations and duplications of putative cytokinin two-component regulators in the rice chromosomes (cv. Nipponbare). Ovals on the chromosomes represent centromeres.]]&lt;br /&gt;

OsRR6 was expressed mostly in roots and leaves.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The transcript levels of OsRR2, 3, 4, 6, 7,and 9 were significantly higher in etiolated seedlings as compared to green seedlings (Fig. 6)[4].&lt;br /&gt;

===Evolution===&lt;br /&gt;
&lt;br /&gt;
The type-A RRs are mainly composed of a receiver domain with short N- and C-terminal extensions [2], essentially similar to the E. coli response regulator (RR) CheY involved in chemotaxis, and lack a typical output domain(3). All the OsRR proteins also contain the highly conserved Lys and two Asp residues (D-D-K) in the receiver domain (Fig. 7B, C).However, OsRR6 and OsRR7 have N-terminal extensions rich in gly and asp residues (Fig. 7C). These N- and C-terminal variable regions may play a role in their localization to different cellular compartments.No homolog of OsRR6 was found within the duplicated region, suggesting the involvement of gene loss or more localized duplications[4].  &lt;br /&gt;

OsRR6 is a kind of CK-inducible type-A response regulator in rice[2].&lt;br /&gt;
==Annotated Information==&lt;br /&gt;
===Function===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is a kind of CK-inducible type-A response regulator[2].The type-A response regulators are relatively small, containing a receiver domain along with short N- and C-terminal extensions. &lt;br /&gt;
&lt;br /&gt;
The expression of a majority of OsRR genes was not significantly altered under stress, with the notable exception of OsRR6. The expression of OsRR6 gene was induced to significant levels by salt, dehydration and low temperature treatments (Fig. 1), and results were reproducible. This indicates that OsRR6 may play an important role in abiotic stress signaling in rice, besides acting as a component in cytokinin signaling[1].&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
[[File:Fig1.png|300px|thumb|left|Fig.1]]&lt;br /&gt;
Fig.1: Changes in transcript levels of the OsRR6 gene in response to different stress treatments. The transcript levels of OsRR6 gene in 6-day-old light-grown seedlings treated with ABA, NaCl, mannitol and cold for 6 h, were plotted as the relative expression (fold) of the seedlings mock-treated for the same duration.&lt;br /&gt;
&lt;br /&gt;
The induction of OsRR6 by different abiotic stress stimuli provides a molecular link between stress and cytokinin signaling as well[1].&lt;br /&gt;
&lt;br /&gt;
Overexpression of OsRR6 also affected the expression of CK-responsive genes[2].&lt;br /&gt;
&lt;br /&gt;
OsRR6-ox plants displayed altered morphologies and changes in CK metabolism, probably due to changes in the gene regulatory network[2].&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Generated transgenic rice plants that overexpress OsRR6 (OsRR6-ox) by fusing its coding sequence to the rice actin1 (Act1) promoter, because this promoter generally produces much higher levels of constitutive expression in rice than the cauliflower mosaic virus(CaMV) 35S promoter. Callus transformed with Act1::OsRR6 showed severe retardation of shoot regeneration compared with callus transformed with a control vector (Fig. 2)[2].&lt;br /&gt;
[[File:Fig2.png|300px|thumb|left|Fig.2: OsRR6 represses shoot regeneration in rice callus. Callus was transformed with Agrobacterium carrying a binary vector pActnos/Hmz (Vec.), Act1::OsRR6 (OsRR6) or Act1::OsRR6D103E (OsRR6D103E). Calli were selected with hygromycin B and grown on regeneration agar plates for 6 weeks.]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Moreover, each of 20 OsRR6D103E-ox independent lines was indistinguishable from plants transformed with a control vector (control plants; Fig. 3A, B). These results support the hypothesis that growth defects associated with OsRR6 overexpression are due to a requirement for phosphorylation of OsRR6[2].&lt;br /&gt;
[[File:Fig3.png|300px|thumb|left|Fig.3: Morphologies of transgenic plants overexpressing OsRR6. OsRR6-ox transgenic plants (T0 generation) were grown on MS-agar plates containing hygromycin B for 7 d, and then hydroponically grown for 75 d. Transgenic plants, transformed with vector pActnos/Hmz (Vec.) or Act1::OsRR6D103E (OsRR6D103E-ox), were also grown under the same conditions. The typical phenotype of each transgenic line and their panicles are shown in (A) and (B). Total RNA samples were prepared from the shoots of each transgenic plant. (C) Semiquantitative RT–PCR analysis of the OsRR6 gene in the transgenic lines. OsAct1 is an extraction and loading control.]]&lt;br /&gt;
&lt;br /&gt;
Future analyses of knockout or RNA interference mutants of OsRR6 will enable us to define further its possible participation in stress responses.&lt;br /&gt;
&lt;br /&gt;
===Expression===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2  (Fig. 4)[4]. &lt;br /&gt;
[[File:Fig4.png|200px|thumb|right|Fig.4:Locations and duplications of putative cytokinin two-component regulators in the rice chromosomes (cv. Nipponbare). Ovals on the chromosomes represent centromeres.]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The OsRR genes express differentially in various organs examined, and also in response to light[1]. Most of the OsRR genes were expressed at relatively higher level in mature tissues (leaves and flowers).The majority of the type-A OsRR genes (OsRR2–9 and OsRR11) were expressed at various levels in roots, stems, leaves, and spikelets (Fig.5)([4]. OsRR6 was expressed mostly in roots and leaves.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The transcript levels of OsRR2, 3, 4, 6, 7,and 9 were significantly higher in etiolated seedlings as compared to green seedlings (Fig. 6)[4].&lt;br /&gt;
[[File:Fig5.png|200px|thumb|right|Fig.5:The analysis of the response of the system genes family to cytokinin by RT-PCR.

OsACTIN primers were used as a template control.]]&lt;br /&gt;

OsRR6 is a kind of CK-inducible type-A response regulator in rice[2].&lt;br /&gt;
==Annotated Information==&lt;br /&gt;
===Function===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is a kind of CK-inducible type-A response regulator[2].The type-A response regulators are relatively small, containing a receiver domain along with short N- and C-terminal extensions. &lt;br /&gt;
&lt;br /&gt;
The expression of a majority of OsRR genes was not significantly altered under stress, with the notable exception of OsRR6. The expression of OsRR6 gene was induced to significant levels by salt, dehydration and low temperature treatments (Fig. 1), and results were reproducible. This indicates that OsRR6 may play an important role in abiotic stress signaling in rice, besides acting as a component in cytokinin signaling[1].&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
[[File:Fig1.png|300px|thumb|left|Fig.1: Changes in transcript levels of the OsRR6 gene in response to different stress treatments. The transcript levels of OsRR6 gene in 6-day-old light-grown seedlings treated with ABA, NaCl, mannitol and cold for 6 h, were plotted as the relative expression (fold) of the seedlings mock-treated for the same duration.]]&lt;br /&gt;
The induction of OsRR6 by different abiotic stress stimuli provides a molecular link between stress and cytokinin signaling as well[1].&lt;br /&gt;
&lt;br /&gt;
Overexpression of OsRR6 also affected the expression of CK-responsive genes[2].&lt;br /&gt;
&lt;br /&gt;
OsRR6-ox plants displayed altered morphologies and changes in CK metabolism, probably due to changes in the gene regulatory network[2].&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Generated transgenic rice plants that overexpress OsRR6 (OsRR6-ox) by fusing its coding sequence to the rice actin1 (Act1) promoter, because this promoter generally produces much higher levels of constitutive expression in rice than the cauliflower mosaic virus(CaMV) 35S promoter. Callus transformed with Act1::OsRR6 showed severe retardation of shoot regeneration compared with callus transformed with a control vector (Fig. 2)[2].&lt;br /&gt;
[[File:Fig2.png|300px|thumb|left|Fig.2: OsRR6 represses shoot regeneration in rice callus. Callus was transformed with Agrobacterium carrying a binary vector pActnos/Hmz (Vec.), Act1::OsRR6 (OsRR6) or Act1::OsRR6D103E (OsRR6D103E). Calli were selected with hygromycin B and grown on regeneration agar plates for 6 weeks.]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Moreover, each of 20 OsRR6D103E-ox independent lines was indistinguishable from plants transformed with a control vector (control plants; Fig. 3A, B). These results support the hypothesis that growth defects associated with OsRR6 overexpression are due to a requirement for phosphorylation of OsRR6[2].&lt;br /&gt;
[[File:Fig3.png|300px|thumb|left|Fig.3: Morphologies of transgenic plants overexpressing OsRR6. OsRR6-ox transgenic plants (T0 generation) were grown on MS-agar plates containing hygromycin B for 7 d, and then hydroponically grown for 75 d. Transgenic plants, transformed with vector pActnos/Hmz (Vec.) or Act1::OsRR6D103E (OsRR6D103E-ox), were also grown under the same conditions. The typical phenotype of each transgenic line and their panicles are shown in (A) and (B). Total RNA samples were prepared from the shoots of each transgenic plant. (C) Semiquantitative RT–PCR analysis of the OsRR6 gene in the transgenic lines. OsAct1 is an extraction and loading control.]]&lt;br /&gt;
&lt;br /&gt;
Future analyses of knockout or RNA interference mutants of OsRR6 will enable us to define further its possible participation in stress responses.&lt;br /&gt;
&lt;br /&gt;
===Expression===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2  (Fig. 4)[4]. &lt;br /&gt;
[[File:Fig4.png|200px|thumb|right|Fig.4:Locations and duplications of putative cytokinin two-component regulators in the rice chromosomes (cv. Nipponbare). Ovals on the chromosomes represent centromeres.]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The OsRR genes express differentially in various organs examined, and also in response to light[1]. Most of the OsRR genes were expressed at relatively higher level in mature tissues (leaves and flowers).The majority of the type-A OsRR genes (OsRR2–9 and OsRR11) were expressed at various levels in roots, stems, leaves, and spikelets (Fig.5)([4]. OsRR6 was expressed mostly in roots and leaves.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The transcript levels of OsRR2, 3, 4, 6, 7,and 9 were significantly higher in etiolated seedlings as compared to green seedlings (Fig. 6)[4].&lt;br /&gt;
[[File:Fig5.png|200px|thumb|right|Fig.5:The analysis of the response of the system genes family to cytokinin by RT-PCR. RNA was isolated from roots and leaves from Nipponbare rice growing in liquid nutrient medium either with 1 μM 6-benzylaminopurine (6-BA) for 4 h or with no 6-BA. OsACTIN primers were used as a template control.]]&lt;br /&gt;

The relative mRNA levels of individual OsRR genes normalized with respect to housekeeping gene, UBQ5, in different tissues (GS, green seedlings; ES, etiolated seedlings; S, green shoots]]&lt;br /&gt;
&lt;br /&gt;
===Evolution===&lt;br /&gt;
&lt;br /&gt;
The type-A RRs are mainly composed of a receiver domain with short N- and C-terminal extensions [2], essentially similar to the E. coli response regulator (RR) CheY involved in chemotaxis, and lack a typical output domain(3). All the OsRR proteins also contain the highly conserved Lys and two Asp residues (D-D-K) in the receiver domain (Fig. 7B, C).However, OsRR6 and OsRR7 have N-terminal extensions rich in gly and asp residues (Fig. 7C). These N- and C-terminal variable regions may play a role in their localization to different cellular compartments.No homolog of OsRR6 was found within the duplicated region, suggesting the involvement of gene loss or more localized duplications[4].  &lt;br /&gt;

OsRR6 is a kind of CK-inducible type-A response regulator in rice[2].&lt;br /&gt;
==Annotated Information==&lt;br /&gt;
===Function===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is a kind of CK-inducible type-A response regulator[2].The type-A response regulators are relatively small, containing a receiver domain along with short N- and C-terminal extensions. &lt;br /&gt;
&lt;br /&gt;
The expression of a majority of OsRR genes was not significantly altered under stress, with the notable exception of OsRR6. The expression of OsRR6 gene was induced to significant levels by salt, dehydration and low temperature treatments (Fig. 1), and results were reproducible. This indicates that OsRR6 may play an important role in abiotic stress signaling in rice, besides acting as a component in cytokinin signaling[1].&lt;br /&gt;
&lt;br /&gt;
The induction of OsRR6 by different abiotic stress stimuli provides a molecular link between stress and cytokinin signaling as well[1].&lt;br /&gt;
&lt;br /&gt;
Overexpression of OsRR6 also affected the expression of CK-responsive genes[2].&lt;br /&gt;
&lt;br /&gt;
OsRR6-ox plants displayed altered morphologies and changes in CK metabolism, probably due to changes in the gene regulatory network[2].&lt;br /&gt;
[[File:Fig1.png|200px|thumb|left|Fig.1: Changes in transcript levels of the OsRR6 gene in response to different stress treatments. The transcript levels of OsRR6 gene in 6-day-old light-grown seedlings treated with ABA, NaCl, mannitol and cold for 6 h, were plotted as the relative expression (fold) of the seedlings mock-treated for the same duration.]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Generated transgenic rice plants that overexpress OsRR6 (OsRR6-ox) by fusing its coding sequence to the rice actin1 (Act1) promoter, because this promoter generally produces much higher levels of constitutive expression in rice than the cauliflower mosaic virus(CaMV) 35S promoter. Callus transformed with Act1::OsRR6 showed severe retardation of shoot regeneration compared with callus transformed with a control vector (Fig. 2)[2].&lt;br /&gt;
[[File:Fig2.png|200px|thumb|left|Fig.2: OsRR6 represses shoot regeneration in rice callus. Callus was transformed with Agrobacterium carrying a binary vector pActnos/Hmz (Vec.), Act1::OsRR6 (OsRR6) or Act1::OsRR6D103E (OsRR6D103E). Calli were selected with hygromycin B and grown on regeneration agar plates for 6 weeks.]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Moreover, each of 20 OsRR6D103E-ox independent lines was indistinguishable from plants transformed with a control vector (control plants; Fig. 3A, B). These results support the hypothesis that growth defects associated with OsRR6 overexpression are due to a requirement for phosphorylation of OsRR6[2].&lt;br /&gt;
[[File:Fig3.png|200px|thumb|left|Fig.3: Morphologies of transgenic plants overexpressing OsRR6. OsRR6-ox transgenic plants (T0 generation) were grown on MS-agar plates containing hygromycin B for 7 d, and then hydroponically grown for 75 d. Transgenic plants, transformed with vector pActnos/Hmz (Vec.) or Act1::OsRR6D103E (OsRR6D103E-ox), were also grown under the same conditions. The typical phenotype of each transgenic line and their panicles are shown in (A) and (B). Total RNA samples were prepared from the shoots of each transgenic plant. (C) Semiquantitative RT–PCR analysis of the OsRR6 gene in the transgenic lines. OsAct1 is an extraction and loading control.]]&lt;br /&gt;
&lt;br /&gt;
Future analyses of knockout or RNA interference mutants of OsRR6 will enable us to define further its possible participation in stress responses.&lt;br /&gt;
&lt;br /&gt;
===Expression===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2  (Fig. 4)[4]. &lt;br /&gt;
[[File:Fig4.png|200px|thumb|right|Fig.4:Locations and duplications of putative cytokinin two-component regulators in the rice chromosomes (cv. Nipponbare). Ovals on the chromosomes represent centromeres.]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The OsRR genes express differentially in various organs examined, and also in response to light[1]. Most of the OsRR genes were expressed at relatively higher level in mature tissues (leaves and flowers).The majority of the type-A OsRR genes (OsRR2–9 and OsRR11) were expressed at various levels in roots, stems, leaves, and spikelets (Fig.5)([4]. OsRR6 was expressed mostly in roots and leaves.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The transcript levels of OsRR2, 3, 4, 6, 7,and 9 were significantly higher in etiolated seedlings as compared to green seedlings (Fig. 6)[4].&lt;br /&gt;
[[File:Fig5.png|200px|thumb|right|Fig.5:The analysis of the response of the system genes family to cytokinin by RT-PCR. RNA was isolated from roots and leaves from Nipponbare rice growing in liquid nutrient medium either with 1 μM 6-benzylaminopurine (6-BA) for 4 h or with no 6-BA. OsACTIN primers were used as a template control.]]&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
[[File:Fig6.png|200px|thumb|right|Fig.6:Real-time PCR analysis showing the organ-specific expression profiles of individual OsRR genes. The relative mRNA levels of individual OsRR genes normalized with respect to housekeeping gene, UBQ5, in different tissues (GS, green seedlings; ES, etiolated seedlings; S, green shoots]]&lt;br /&gt;
&lt;br /&gt;
===Evolution===&lt;br /&gt;
&lt;br /&gt;
The type-A RRs are mainly composed of a receiver domain with short N- and C-terminal extensions [2], essentially similar to the E. coli response regulator (RR) CheY involved in chemotaxis, and lack a typical output domain(3). All the OsRR proteins also contain the highly conserved Lys and two Asp residues (D-D-K) in the receiver domain (Fig. 7B, C).However, OsRR6 and OsRR7 have N-terminal extensions rich in gly and asp residues (Fig. 7C). These N- and C-terminal variable regions may play a role in their localization to different cellular compartments.No homolog of OsRR6 was found within the duplicated region, suggesting the involvement of gene loss or more localized duplications[4].  &lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
OsRR6 were found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2 that contains the OsRR11 gene [4](Fig. 4).&lt;br /&gt;

These results support the hypothesis that growth defects associated with OsRR6 overexpression are due to a requirement for phosphorylation of OsRR6[2].&lt;br /&gt;

&lt;br /&gt;
===Expression===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2  (Fig. 4)[4]. &lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The OsRR genes express differentially in various organs examined, and also in response to light[1]. Most of the OsRR genes were expressed at relatively higher level in mature tissues (leaves and flowers).The majority of the type-A OsRR genes (OsRR2–9 and OsRR11) were expressed at various levels in roots, stems, leaves, and spikelets (Fig.5)([4]. OsRR6 was expressed mostly in roots and leaves.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The transcript levels of OsRR2, 3, 4, 6, 7,and 9 were significantly higher in etiolated seedlings as compared to green seedlings (Fig. 6)[4].&lt;br /&gt;

OsACTIN primers were used as a template control.]]&lt;br /&gt;

&lt;br /&gt;
===Evolution===&lt;br /&gt;
&lt;br /&gt;
The type-A RRs are mainly composed of a receiver domain with short N- and C-terminal extensions [2], essentially similar to the E. coli response regulator (RR) CheY involved in chemotaxis, and lack a typical output domain(3). All the OsRR proteins also contain the highly conserved Lys and two Asp residues (D-D-K) in the receiver domain (Fig. 7B, C).However, OsRR6 and OsRR7 have N-terminal extensions rich in gly and asp residues (Fig. 7C). These N- and C-terminal variable regions may play a role in their localization to different cellular compartments.No homolog of OsRR6 was found within the duplicated region, suggesting the involvement of gene loss or more localized duplications[4].  &lt;br /&gt;

OsRR6 is a kind of CK-inducible type-A response regulator in rice[2].&lt;br /&gt;
==Annotated Information==&lt;br /&gt;
===Function===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is a kind of CK-inducible type-A response regulator[2].The type-A response regulators are relatively small, containing a receiver domain along with short N- and C-terminal extensions. &lt;br /&gt;
&lt;br /&gt;
The expression of a majority of OsRR genes was not significantly altered under stress, with the notable exception of OsRR6. The expression of OsRR6 gene was induced to significant levels by salt, dehydration and low temperature treatments (Fig. 1), and results were reproducible. This indicates that OsRR6 may play an important role in abiotic stress signaling in rice, besides acting as a component in cytokinin signaling[1].&lt;br /&gt;
&lt;br /&gt;
The induction of OsRR6 by different abiotic stress stimuli provides a molecular link between stress and cytokinin signaling as well[1].&lt;br /&gt;
&lt;br /&gt;
Overexpression of OsRR6 also affected the expression of CK-responsive genes[2].&lt;br /&gt;
&lt;br /&gt;
OsRR6-ox plants displayed altered morphologies and changes in CK metabolism, probably due to changes in the gene regulatory network[2].&lt;br /&gt;
[[File:Fig1.png|200px|thumb|left|Fig.1: Changes in transcript levels of the OsRR6 gene in response to different stress treatments. The transcript levels of OsRR6 gene in 6-day-old light-grown seedlings treated with ABA, NaCl, mannitol and cold for 6 h, were plotted as the relative expression (fold) of the seedlings mock-treated for the same duration.]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Generated transgenic rice plants that overexpress OsRR6 (OsRR6-ox) by fusing its coding sequence to the rice actin1 (Act1) promoter, because this promoter generally produces much higher levels of constitutive expression in rice than the cauliflower mosaic virus(CaMV) 35S promoter. Callus transformed with Act1::OsRR6 showed severe retardation of shoot regeneration compared with callus transformed with a control vector (Fig. 2)[2].&lt;br /&gt;
[[File:Fig2.png|200px|thumb|left|Fig.2: OsRR6 represses shoot regeneration in rice callus. Callus was transformed with Agrobacterium carrying a binary vector pActnos/Hmz (Vec.), Act1::OsRR6 (OsRR6) or Act1::OsRR6D103E (OsRR6D103E). Calli were selected with hygromycin B and grown on regeneration agar plates for 6 weeks.]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Moreover, each of 20 OsRR6D103E-ox independent lines was indistinguishable from plants transformed with a control vector (control plants; Fig. 3A, B). These results support the hypothesis that growth defects associated with OsRR6 overexpression are due to a requirement for phosphorylation of OsRR6[2].&lt;br /&gt;
[[File:Fig3.png|200px|thumb|left|Fig.3: Morphologies of transgenic plants overexpressing OsRR6.

The typical phenotype of each transgenic line and their panicles are shown in (A) and (B). Total RNA samples were prepared from the shoots of each transgenic plant. (C) Semiquantitative RT–PCR analysis of the OsRR6 gene in the transgenic lines. OsAct1 is an extraction and loading control.]]&lt;br /&gt;
&lt;br /&gt;
Future analyses of knockout or RNA interference mutants of OsRR6 will enable us to define further its possible participation in stress responses.&lt;br /&gt;
&lt;br /&gt;
===Expression===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2  (Fig. 4)[4]. &lt;br /&gt;
[[File:Fig4.png|200px|thumb|right|Fig.4:Locations and duplications of putative cytokinin two-component regulators in the rice chromosomes (cv. Nipponbare). Ovals on the chromosomes represent centromeres.]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The OsRR genes express differentially in various organs examined, and also in response to light[1]. Most of the OsRR genes were expressed at relatively higher level in mature tissues (leaves and flowers).The majority of the type-A OsRR genes (OsRR2–9 and OsRR11) were expressed at various levels in roots, stems, leaves, and spikelets (Fig.5)([4]. OsRR6 was expressed mostly in roots and leaves.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The transcript levels of OsRR2, 3, 4, 6, 7,and 9 were significantly higher in etiolated seedlings as compared to green seedlings (Fig. 6)[4].&lt;br /&gt;
[[File:Fig5.png|200px|thumb|right|Fig.5:The analysis of the response of the system genes family to cytokinin by RT-PCR. RNA was isolated from roots and leaves from Nipponbare rice growing in liquid nutrient medium either with 1 μM 6-benzylaminopurine (6-BA) for 4 h or with no 6-BA. OsACTIN primers were used as a template control.]]&lt;br /&gt;

The type-A RRs are mainly composed of a receiver domain with short N- and C-terminal extensions [2], essentially similar to the E. coli response regulator (RR) CheY involved in chemotaxis, and lack a typical output domain(3). All the OsRR proteins also contain the highly conserved Lys and two Asp residues (D-D-K) in the receiver domain (Fig. 7B, C).However, OsRR6 and OsRR7 have N-terminal extensions rich in gly and asp residues (Fig. 7C). These N- and C-terminal variable regions may play a role in their localization to different cellular compartments.No homolog of OsRR6 was found within the duplicated region, suggesting the involvement of gene loss or more localized duplications[4].  &lt;br /&gt;

OsRR6 is a kind of CK-inducible type-A response regulator in rice[2].&lt;br /&gt;
==Annotated Information==&lt;br /&gt;
===Function===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is a kind of CK-inducible type-A response regulator[2].The type-A response regulators are relatively small, containing a receiver domain along with short N- and C-terminal extensions. &lt;br /&gt;
&lt;br /&gt;
The expression of a majority of OsRR genes was not significantly altered under stress, with the notable exception of OsRR6. The expression of OsRR6 gene was induced to significant levels by salt, dehydration and low temperature treatments (Fig. 1), and results were reproducible. This indicates that OsRR6 may play an important role in abiotic stress signaling in rice, besides acting as a component in cytokinin signaling[1].&lt;br /&gt;
&lt;br /&gt;
The induction of OsRR6 by different abiotic stress stimuli provides a molecular link between stress and cytokinin signaling as well[1].&lt;br /&gt;
&lt;br /&gt;
Overexpression of OsRR6 also affected the expression of CK-responsive genes[2].&lt;br /&gt;
&lt;br /&gt;
OsRR6-ox plants displayed altered morphologies and changes in CK metabolism, probably due to changes in the gene regulatory network[2].&lt;br /&gt;
[[File:Fig1.png|200px|thumb|left|Fig.1: Changes in transcript levels of the OsRR6 gene in response to different stress treatments. The transcript levels of OsRR6 gene in 6-day-old light-grown seedlings treated with ABA, NaCl, mannitol and cold for 6 h, were plotted as the relative expression (fold) of the seedlings mock-treated for the same duration.]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Generated transgenic rice plants that overexpress OsRR6 (OsRR6-ox) by fusing its coding sequence to the rice actin1 (Act1) promoter, because this promoter generally produces much higher levels of constitutive expression in rice than the cauliflower mosaic virus(CaMV) 35S promoter. Callus transformed with Act1::OsRR6 showed severe retardation of shoot regeneration compared with callus transformed with a control vector (Fig. 2)[2].&lt;br /&gt;
[[File:Fig2.png|200px|thumb|left|Fig.2: OsRR6 represses shoot regeneration in rice callus. Callus was transformed with Agrobacterium carrying a binary vector pActnos/Hmz (Vec.), Act1::OsRR6 (OsRR6) or Act1::OsRR6D103E (OsRR6D103E). Calli were selected with hygromycin B and grown on regeneration agar plates for 6 weeks.]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Moreover, each of 20 OsRR6D103E-ox independent lines was indistinguishable from plants transformed with a control vector (control plants; Fig. 3A, B). These results support the hypothesis that growth defects associated with OsRR6 overexpression are due to a requirement for phosphorylation of OsRR6[2].&lt;br /&gt;
[[File:Fig3.png|200px|thumb|left|Fig.3: Morphologies of transgenic plants overexpressing OsRR6. OsRR6-ox transgenic plants (T0 generation) were grown on MS-agar plates containing hygromycin B for 7 d, and then hydroponically grown for 75 d. Transgenic plants, transformed with vector pActnos/Hmz (Vec.) or Act1::OsRR6D103E (OsRR6D103E-ox), were also grown under the same conditions. The typical phenotype of each transgenic line and their panicles are shown in (A) and (B). Total RNA samples were prepared from the shoots of each transgenic plant. (C) Semiquantitative RT–PCR analysis of the OsRR6 gene in the transgenic lines. OsAct1 is an extraction and loading control.]]&lt;br /&gt;
&lt;br /&gt;
Future analyses of knockout or RNA interference mutants of OsRR6 will enable us to define further its possible participation in stress responses.&lt;br /&gt;
&lt;br /&gt;
===Expression===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2  (Fig. 4)[4]. &lt;br /&gt;
[[File:Fig4.png|200px|thumb|right|Fig.4:Locations and duplications of putative cytokinin two-component regulators in the rice chromosomes (cv. Nipponbare). Ovals on the chromosomes represent centromeres.]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The OsRR genes express differentially in various organs examined, and also in response to light[1]. Most of the OsRR genes were expressed at relatively higher level in mature tissues (leaves and flowers).The majority of the type-A OsRR genes (OsRR2–9 and OsRR11) were expressed at various levels in roots, stems, leaves, and spikelets (Fig.5)([4]. OsRR6 was expressed mostly in roots and leaves.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The transcript levels of OsRR2, 3, 4, 6, 7,and 9 were significantly higher in etiolated seedlings as compared to green seedlings (Fig. 6)[4].&lt;br /&gt;
[[File:Fig5.png|200px|thumb|right|Fig.5:The analysis of the response of the system genes family to cytokinin by RT-PCR. RNA was isolated from roots and leaves from Nipponbare rice growing in liquid nutrient medium either with 1 μM 6-benzylaminopurine (6-BA) for 4 h or with no 6-BA. OsACTIN primers were used as a template control.]]&lt;br /&gt;

The relative mRNA levels of individual OsRR genes normalized with respect to housekeeping gene, UBQ5, in different tissues (GS, green seedlings; ES, etiolated seedlings; S, green shoots]]&lt;br /&gt;
&lt;br /&gt;
===Evolution===&lt;br /&gt;
&lt;br /&gt;
The type-A RRs are mainly composed of a receiver domain with short N- and C-terminal extensions [2], essentially similar to the E. coli response regulator (RR) CheY involved in chemotaxis, and lack a typical output domain(3). All the OsRR proteins also contain the highly conserved Lys and two Asp residues (D-D-K) in the receiver domain (Fig. 7B, C).However, OsRR6 and OsRR7 have N-terminal extensions rich in gly and asp residues (Fig. 7C). These N- and C-terminal variable regions may play a role in their localization to different cellular compartments.&lt;br /&gt;
[[File:fig7]]&lt;br /&gt;
 No homolog of OsRR6 was found within the duplicated region, suggesting the involvement of gene loss or more localized duplications[4].  &lt;br /&gt;
&lt;br /&gt;
OsRR6 were found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2 that contains the OsRR11 gene [4](Fig. 4).&lt;br /&gt;

OsRR6 is a kind of CK-inducible type-A response regulator in rice[2].&lt;br /&gt;
==Annotated Information==&lt;br /&gt;
===Function===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is a kind of CK-inducible type-A response regulator[2].The type-A response regulators are relatively small, containing a receiver domain along with short N- and C-terminal extensions. &lt;br /&gt;
&lt;br /&gt;
The expression of a majority of OsRR genes was not significantly altered under stress, with the notable exception of OsRR6. The expression of OsRR6 gene was induced to significant levels by salt, dehydration and low temperature treatments (Fig. 1), and results were reproducible. This indicates that OsRR6 may play an important role in abiotic stress signaling in rice, besides acting as a component in cytokinin signaling[1].&lt;br /&gt;
&lt;br /&gt;
The induction of OsRR6 by different abiotic stress stimuli provides a molecular link between stress and cytokinin signaling as well[1].&lt;br /&gt;
&lt;br /&gt;
Overexpression of OsRR6 also affected the expression of CK-responsive genes[2].&lt;br /&gt;
&lt;br /&gt;
OsRR6-ox plants displayed altered morphologies and changes in CK metabolism, probably due to changes in the gene regulatory network[2].&lt;br /&gt;
[[File:Fig1.png|200px|thumb|left|Fig.1: Changes in transcript levels of the OsRR6 gene in response to different stress treatments. The transcript levels of OsRR6 gene in 6-day-old light-grown seedlings treated with ABA, NaCl, mannitol and cold for 6 h, were plotted as the relative expression (fold) of the seedlings mock-treated for the same duration.]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Generated transgenic rice plants that overexpress OsRR6 (OsRR6-ox) by fusing its coding sequence to the rice actin1 (Act1) promoter, because this promoter generally produces much higher levels of constitutive expression in rice than the cauliflower mosaic virus(CaMV) 35S promoter. Callus transformed with Act1::OsRR6 showed severe retardation of shoot regeneration compared with callus transformed with a control vector (Fig. 2)[2].&lt;br /&gt;
[[File:Fig2.png|200px|thumb|left|Fig.2: OsRR6 represses shoot regeneration in rice callus. Callus was transformed with Agrobacterium carrying a binary vector pActnos/Hmz (Vec.), Act1::OsRR6 (OsRR6) or Act1::OsRR6D103E (OsRR6D103E). Calli were selected with hygromycin B and grown on regeneration agar plates for 6 weeks.]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Moreover, each of 20 OsRR6D103E-ox independent lines was indistinguishable from plants transformed with a control vector (control plants; Fig. 3A, B). These results support the hypothesis that growth defects associated with OsRR6 overexpression are due to a requirement for phosphorylation of OsRR6[2].&lt;br /&gt;
[[File:Fig3.png|200px|thumb|left|Fig.3: Morphologies of transgenic plants overexpressing OsRR6. OsRR6-ox transgenic plants (T0 generation) were grown on MS-agar plates containing hygromycin B for 7 d, and then hydroponically grown for 75 d. Transgenic plants, transformed with vector pActnos/Hmz (Vec.) or Act1::OsRR6D103E (OsRR6D103E-ox), were also grown under the same conditions. The typical phenotype of each transgenic line and their panicles are shown in (A) and (B). Total RNA samples were prepared from the shoots of each transgenic plant. (C) Semiquantitative RT–PCR analysis of the OsRR6 gene in the transgenic lines. OsAct1 is an extraction and loading control.]]&lt;br /&gt;
&lt;br /&gt;
Future analyses of knockout or RNA interference mutants of OsRR6 will enable us to define further its possible participation in stress responses.&lt;br /&gt;
&lt;br /&gt;
===Expression===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2  (Fig. 4)[4]. &lt;br /&gt;
[[File:fig4]]&lt;br /&gt;
&lt;br /&gt;
The OsRR genes express differentially in various organs examined, and also in response to light[1]. Most of the OsRR genes were expressed at relatively higher level in mature tissues (leaves and flowers).The majority of the type-A OsRR genes (OsRR2–9 and OsRR11) were expressed at various levels in roots, stems, leaves, and spikelets (Fig.5)([4]. OsRR6 was expressed mostly in roots and leaves.&lt;br /&gt;
&lt;br /&gt;
The transcript levels of OsRR2, 3, 4, 6, 7,and 9 were significantly higher in etiolated seedlings as compared to green seedlings (Fig. 6)[4].&lt;br /&gt;
[[File:fig5]]&lt;br /&gt;
&lt;br /&gt;
[[File:fig6]]&lt;br /&gt;
&lt;br /&gt;
===Evolution===&lt;br /&gt;
&lt;br /&gt;
The type-A RRs are mainly composed of a receiver domain with short N- and C-terminal extensions [2], essentially similar to the E. coli response regulator (RR) CheY involved in chemotaxis, and lack a typical output domain(3). All the OsRR proteins also contain the highly conserved Lys and two Asp residues (D-D-K) in the receiver domain (Fig. 7B, C).However, OsRR6 and OsRR7 have N-terminal extensions rich in gly and asp residues (Fig. 7C). These N- and C-terminal variable regions may play a role in their localization to different cellular compartments.&lt;br /&gt;
[[File:fig7]]&lt;br /&gt;
 No homolog of OsRR6 was found within the duplicated region, suggesting the involvement of gene loss or more localized duplications[4].  &lt;br /&gt;
&lt;br /&gt;
OsRR6 were found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2 that contains the OsRR11 gene [4](Fig. 4).&lt;br /&gt;

Future analyses of knockout or RNA interference mutants of OsRR6 will enable us to define further its possible participation in stress responses.&lt;br /&gt;
&lt;br /&gt;
===Expression===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2  (Fig. 4)[4]. &lt;br /&gt;
[[File:fig4]]&lt;br /&gt;
&lt;br /&gt;
The OsRR genes express differentially in various organs examined, and also in response to light[1]. Most of the OsRR genes were expressed at relatively higher level in mature tissues (leaves and flowers).The majority of the type-A OsRR genes (OsRR2–9 and OsRR11) were expressed at various levels in roots, stems, leaves, and spikelets (Fig.5)([4]. OsRR6 was expressed mostly in roots and leaves.&lt;br /&gt;
&lt;br /&gt;
The transcript levels of OsRR2, 3, 4, 6, 7,and 9 were significantly higher in etiolated seedlings as compared to green seedlings (Fig. 6)[4].&lt;br /&gt;
[[File:fig5]]&lt;br /&gt;
&lt;br /&gt;
[[File:fig6]]&lt;br /&gt;
&lt;br /&gt;
===Evolution===&lt;br /&gt;
&lt;br /&gt;
The type-A RRs are mainly composed of a receiver domain with short N- and C-terminal extensions [2], essentially similar to the E. coli response regulator (RR) CheY involved in chemotaxis, and lack a typical output domain(3). All the OsRR proteins also contain the highly conserved Lys and two Asp residues (D-D-K) in the receiver domain (Fig. 7B, C).However, OsRR6 and OsRR7 have N-terminal extensions rich in gly and asp residues (Fig. 7C). These N- and C-terminal variable regions may play a role in their localization to different cellular compartments.&lt;br /&gt;
[[File:fig7]]&lt;br /&gt;
 No homolog of OsRR6 was found within the duplicated region, suggesting the involvement of gene loss or more localized duplications[4].  &lt;br /&gt;
&lt;br /&gt;
OsRR6 were found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2 that contains the OsRR11 gene [4](Fig. 4).&lt;br /&gt;

OsRR6 is a kind of CK-inducible type-A response regulator in rice[2].&lt;br /&gt;
==Annotated Information==&lt;br /&gt;
===Function===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is a kind of CK-inducible type-A response regulator[2].The type-A response regulators are relatively small, containing a receiver domain along with short N- and C-terminal extensions. &lt;br /&gt;
&lt;br /&gt;
The expression of a majority of OsRR genes was not significantly altered under stress, with the notable exception of OsRR6. The expression of OsRR6 gene was induced to significant levels by salt, dehydration and low temperature treatments (Fig. 1), and results were reproducible. This indicates that OsRR6 may play an important role in abiotic stress signaling in rice, besides acting as a component in cytokinin signaling[1].&lt;br /&gt;
&lt;br /&gt;
The induction of OsRR6 by different abiotic stress stimuli provides a molecular link between stress and cytokinin signaling as well[1].&lt;br /&gt;
&lt;br /&gt;
Overexpression of OsRR6 also affected the expression of CK-responsive genes[2].&lt;br /&gt;
&lt;br /&gt;
OsRR6-ox plants displayed altered morphologies and changes in CK metabolism, probably due to changes in the gene regulatory network[2].&lt;br /&gt;
[[File:Fig1.png|200px|thumb|left|Fig1 Changes in transcript levels of the OsRR6 gene in response to different stress treatments. The transcript levels of OsRR6 gene in 6-day-old light-grown seedlings treated with ABA, NaCl, mannitol and cold for 6 h, were plotted as the relative expression (fold) of the seedlings mock-treated for the same duration.]]&lt;br /&gt;
&lt;br /&gt;
Generated transgenic rice plants that overexpress OsRR6 (OsRR6-ox) by fusing its coding sequence to the rice actin1 (Act1) promoter, because this promoter generally produces much higher levels of constitutive expression in rice than the cauliflower mosaic virus(CaMV) 35S promoter. Callus transformed with Act1::OsRR6 showed severe retardation of shoot regeneration compared with callus transformed with a control vector (Fig. 2)[2].&lt;br /&gt;
[[File:fig2]]&lt;br /&gt;
&lt;br /&gt;
Moreover, each of 20 OsRR6D103E-ox independent lines was indistinguishable from plants transformed with a control vector (control plants; Fig. 3A, B). These results support the hypothesis that growth defects associated with OsRR6 overexpression are due to a requirement for phosphorylation of OsRR6[2].&lt;br /&gt;
[[File:fig3]]&lt;br /&gt;

Future analyses of knockout or RNA interference mutants of OsRR6 will enable us to define further its possible participation in stress responses.&lt;br /&gt;

Future analyses of knockout or RNA interference mutants of OsRR6 will enable us to define further its possible participation in stress responses.&lt;br /&gt;
&lt;br /&gt;
===Expression===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2  (Fig. 4)[4]. &lt;br /&gt;
[[File:fig4]]&lt;br /&gt;
&lt;br /&gt;
The OsRR genes express differentially in various organs examined, and also in response to light[1]. Most of the OsRR genes were expressed at relatively higher level in mature tissues (leaves and flowers).The majority of the type-A OsRR genes (OsRR2–9 and OsRR11) were expressed at various levels in roots, stems, leaves, and spikelets (Fig.5)([4]. OsRR6 was expressed mostly in roots and leaves.&lt;br /&gt;
&lt;br /&gt;
The transcript levels of OsRR2, 3, 4, 6, 7,and 9 were significantly higher in etiolated seedlings as compared to green seedlings (Fig. 6)[4].&lt;br /&gt;
[[File:fig5]]&lt;br /&gt;
&lt;br /&gt;
[[File:fig6]]&lt;br /&gt;
&lt;br /&gt;
===Evolution===&lt;br /&gt;
&lt;br /&gt;
The type-A RRs are mainly composed of a receiver domain with short N- and C-terminal extensions [2], essentially similar to the E. coli response regulator (RR) CheY involved in chemotaxis, and lack a typical output domain(3). All the OsRR proteins also contain the highly conserved Lys and two Asp residues (D-D-K) in the receiver domain (Fig. 7B, C).However, OsRR6 and OsRR7 have N-terminal extensions rich in gly and asp residues (Fig. 7C). These N- and C-terminal variable regions may play a role in their localization to different cellular compartments.&lt;br /&gt;
[[File:fig7]]&lt;br /&gt;
 No homolog of OsRR6 was found within the duplicated region, suggesting the involvement of gene loss or more localized duplications[4].  &lt;br /&gt;
&lt;br /&gt;
OsRR6 were found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2 that contains the OsRR11 gene [4](Fig. 4).&lt;br /&gt;

OsRR6 is a kind of CK-inducible type-A response regulator in rice[2].&lt;br /&gt;
==Annotated Information==&lt;br /&gt;
===Function===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is a kind of CK-inducible type-A response regulator[2].The type-A response regulators are relatively small, containing a receiver domain along with short N- and C-terminal extensions. &lt;br /&gt;
&lt;br /&gt;
The expression of a majority of OsRR genes was not significantly altered under stress, with the notable exception of OsRR6. The expression of OsRR6 gene was induced to significant levels by salt, dehydration and low temperature treatments (Fig. 1), and results were reproducible. This indicates that OsRR6 may play an important role in abiotic stress signaling in rice, besides acting as a component in cytokinin signaling[1].&lt;br /&gt;
&lt;br /&gt;
The induction of OsRR6 by different abiotic stress stimuli provides a molecular link between stress and cytokinin signaling as well[1].&lt;br /&gt;
&lt;br /&gt;
Overexpression of OsRR6 also affected the expression of CK-responsive genes[2].&lt;br /&gt;
&lt;br /&gt;
OsRR6-ox plants displayed altered morphologies and changes in CK metabolism, probably due to changes in the gene regulatory network[2].&lt;br /&gt;
[[File:fig1]]&lt;br /&gt;
&lt;br /&gt;
Generated transgenic rice plants that overexpress OsRR6 (OsRR6-ox) by fusing its coding sequence to the rice actin1 (Act1) promoter, because this promoter generally produces much higher levels of constitutive expression in rice than the cauliflower mosaic virus(CaMV) 35S promoter. Callus transformed with Act1::OsRR6 showed severe retardation of shoot regeneration compared with callus transformed with a control vector (Fig. 2)[2].&lt;br /&gt;
[[File:fig2]]&lt;br /&gt;
&lt;br /&gt;
Moreover, each of 20 OsRR6D103E-ox independent lines was indistinguishable from plants transformed with a control vector (control plants; Fig. 3A, B). These results support the hypothesis that growth defects associated with OsRR6 overexpression are due to a requirement for phosphorylation of OsRR6[2].&lt;br /&gt;
[[File:fig3]]&lt;br /&gt;
&lt;br /&gt;
Future analyses of knockout or RNA interference mutants of OsRR6 will enable us to define further its possible participation in stress responses.&lt;br /&gt;
&lt;br /&gt;
===Expression===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2  (Fig. 4)[4]. &lt;br /&gt;

&lt;br /&gt;

The expression of OsRR6 gene was induced to significant levels by salt, dehydration and low temperature treatments (Fig. 1), and results were reproducible. This indicates that OsRR6 may play an important role in abiotic stress signaling in rice, besides acting as a component in cytokinin signaling[1].&lt;br /&gt;
&lt;br /&gt;
The induction of OsRR6 by different abiotic stress stimuli provides a molecular link between stress and cytokinin signaling as well[1].&lt;br /&gt;
&lt;br /&gt;
Overexpression of OsRR6 also affected the expression of CK-responsive genes[2].&lt;br /&gt;
&lt;br /&gt;
OsRR6-ox plants displayed altered morphologies and changes in CK metabolism, probably due to changes in the gene regulatory network[2].&lt;br /&gt;
[[File:fig1.png|200px|thumb|left|替换文字]]&lt;br /&gt;
&lt;br /&gt;
Generated transgenic rice plants that overexpress OsRR6 (OsRR6-ox) by fusing its coding sequence to the rice actin1 (Act1) promoter, because this promoter generally produces much higher levels of constitutive expression in rice than the cauliflower mosaic virus(CaMV) 35S promoter. Callus transformed with Act1::OsRR6 showed severe retardation of shoot regeneration compared with callus transformed with a control vector (Fig. 2)[2].&lt;br /&gt;
[[File:fig2]]&lt;br /&gt;
&lt;br /&gt;
Moreover, each of 20 OsRR6D103E-ox independent lines was indistinguishable from plants transformed with a control vector (control plants; Fig. 3A, B). These results support the hypothesis that growth defects associated with OsRR6 overexpression are due to a requirement for phosphorylation of OsRR6[2].&lt;br /&gt;
[[File:fig3]]&lt;br /&gt;
&lt;br /&gt;
Future analyses of knockout or RNA interference mutants of OsRR6 will enable us to define further its possible participation in stress responses.&lt;br /&gt;
&lt;br /&gt;
===Expression===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2  (Fig. 4)[4]. &lt;br /&gt;
[[File:fig4]]&lt;br /&gt;
&lt;br /&gt;
The OsRR genes express differentially in various organs examined, and also in response to light[1]. Most of the OsRR genes were expressed at relatively higher level in mature tissues (leaves and flowers).The majority of the type-A OsRR genes (OsRR2–9 and OsRR11) were expressed at various levels in roots, stems, leaves, and spikelets (Fig.5)([4]. OsRR6 was expressed mostly in roots and leaves.&lt;br /&gt;
&lt;br /&gt;
The transcript levels of OsRR2, 3, 4, 6, 7,and 9 were significantly higher in etiolated seedlings as compared to green seedlings (Fig. 6)[4].&lt;br /&gt;
[[File:fig5]]&lt;br /&gt;
&lt;br /&gt;
[[File:fig6]]&lt;br /&gt;
&lt;br /&gt;
===Evolution===&lt;br /&gt;
&lt;br /&gt;
The type-A RRs are mainly composed of a receiver domain with short N- and C-terminal extensions [2], essentially similar to the E. coli response regulator (RR) CheY involved in chemotaxis, and lack a typical output domain(3). All the OsRR proteins also contain the highly conserved Lys and two Asp residues (D-D-K) in the receiver domain (Fig. 7B, C).However, OsRR6 and OsRR7 have N-terminal extensions rich in gly and asp residues (Fig. 7C). These N- and C-terminal variable regions may play a role in their localization to different cellular compartments.&lt;br /&gt;
[[File:fig7]]&lt;br /&gt;
 No homolog of OsRR6 was found within the duplicated region, suggesting the involvement of gene loss or more localized duplications[4].  &lt;br /&gt;
&lt;br /&gt;
OsRR6 were found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2 that contains the OsRR11 gene [4](Fig. 4).&lt;br /&gt;

OsRR6-ox plants displayed altered morphologies and changes in CK metabolism, probably due to changes in the gene regulatory network[2].&lt;br /&gt;
[[File:fig1.png|200px|fig1|left|]]&lt;br /&gt;
&lt;br /&gt;
Generated transgenic rice plants that overexpress OsRR6 (OsRR6-ox) by fusing its coding sequence to the rice actin1 (Act1) promoter, because this promoter generally produces much higher levels of constitutive expression in rice than the cauliflower mosaic virus(CaMV) 35S promoter. Callus transformed with Act1::OsRR6 showed severe retardation of shoot regeneration compared with callus transformed with a control vector (Fig. 2)[2].&lt;br /&gt;
[[File:fig2]]&lt;br /&gt;
&lt;br /&gt;
Moreover, each of 20 OsRR6D103E-ox independent lines was indistinguishable from plants transformed with a control vector (control plants; Fig. 3A, B). These results support the hypothesis that growth defects associated with OsRR6 overexpression are due to a requirement for phosphorylation of OsRR6[2].&lt;br /&gt;
[[File:fig3]]&lt;br /&gt;
&lt;br /&gt;
Future analyses of knockout or RNA interference mutants of OsRR6 will enable us to define further its possible participation in stress responses.&lt;br /&gt;
&lt;br /&gt;
===Expression===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2  (Fig. 4)[4]. &lt;br /&gt;
[[File:fig4]]&lt;br /&gt;
&lt;br /&gt;
The OsRR genes express differentially in various organs examined, and also in response to light[1]. Most of the OsRR genes were expressed at relatively higher level in mature tissues (leaves and flowers).The majority of the type-A OsRR genes (OsRR2–9 and OsRR11) were expressed at various levels in roots, stems, leaves, and spikelets (Fig.5)([4]. OsRR6 was expressed mostly in roots and leaves.&lt;br /&gt;
&lt;br /&gt;
The transcript levels of OsRR2, 3, 4, 6, 7,and 9 were significantly higher in etiolated seedlings as compared to green seedlings (Fig. 6)[4].&lt;br /&gt;
[[File:fig5]]&lt;br /&gt;
&lt;br /&gt;
[[File:fig6]]&lt;br /&gt;
&lt;br /&gt;
===Evolution===&lt;br /&gt;
&lt;br /&gt;
The type-A RRs are mainly composed of a receiver domain with short N- and C-terminal extensions [2], essentially similar to the E. coli response regulator (RR) CheY involved in chemotaxis, and lack a typical output domain(3). All the OsRR proteins also contain the highly conserved Lys and two Asp residues (D-D-K) in the receiver domain (Fig. 7B, C).However, OsRR6 and OsRR7 have N-terminal extensions rich in gly and asp residues (Fig. 7C). These N- and C-terminal variable regions may play a role in their localization to different cellular compartments.&lt;br /&gt;
[[File:fig7]]&lt;br /&gt;
 No homolog of OsRR6 was found within the duplicated region, suggesting the involvement of gene loss or more localized duplications[4].  &lt;br /&gt;
&lt;br /&gt;
OsRR6 were found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2 that contains the OsRR11 gene [4](Fig. 4).&lt;br /&gt;

OsRR6 is a kind of CK-inducible type-A response regulator in rice[2].&lt;br /&gt;
==Annotated Information==&lt;br /&gt;
===Function===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is a kind of CK-inducible type-A response regulator[2].The type-A response regulators are relatively small, containing a receiver domain along with short N- and C-terminal extensions. &lt;br /&gt;
&lt;br /&gt;
The expression of a majority of OsRR genes was not significantly altered under stress, with the notable exception of OsRR6. The expression of OsRR6 gene was induced to significant levels by salt, dehydration and low temperature treatments (Fig. 1), and results were reproducible. This indicates that OsRR6 may play an important role in abiotic stress signaling in rice, besides acting as a component in cytokinin signaling[1].&lt;br /&gt;
&lt;br /&gt;
The induction of OsRR6 by different abiotic stress stimuli provides a molecular link between stress and cytokinin signaling as well[1].&lt;br /&gt;
&lt;br /&gt;
Overexpression of OsRR6 also affected the expression of CK-responsive genes[2].&lt;br /&gt;
&lt;br /&gt;
OsRR6-ox plants displayed altered morphologies and changes in CK metabolism, probably due to changes in the gene regulatory network[2].&lt;br /&gt;
[[File:fig1.png|200px|fig1|left|Changes in transcript levels of the OsRR6 gene in response to different stress treatments. The transcript levels of OsRR6 gene in 6-day-old light-grown seedlings treated with ABA, NaCl, mannitol and cold for 6 h, were plotted as the relative expression (fold) of the seedlings mock-treated for the same duration.]]&lt;br /&gt;

Generated transgenic rice plants that overexpress OsRR6 (OsRR6-ox) by fusing its coding sequence to the rice actin1 (Act1) promoter, because this promoter generally produces much higher levels of constitutive expression in rice than the cauliflower mosaic virus(CaMV) 35S promoter. Callus transformed with Act1::OsRR6 showed severe retardation of shoot regeneration compared with callus transformed with a control vector (Fig. 2)[2].&lt;br /&gt;
[[File:fig2]]&lt;br /&gt;
&lt;br /&gt;
Moreover, each of 20 OsRR6D103E-ox independent lines was indistinguishable from plants transformed with a control vector (control plants; Fig. 3A, B). These results support the hypothesis that growth defects associated with OsRR6 overexpression are due to a requirement for phosphorylation of OsRR6[2].&lt;br /&gt;
[[File:fig3]]&lt;br /&gt;
&lt;br /&gt;
Future analyses of knockout or RNA interference mutants of OsRR6 will enable us to define further its possible participation in stress responses.&lt;br /&gt;
&lt;br /&gt;
===Expression===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2  (Fig. 4)[4]. &lt;br /&gt;
[[File:fig4]]&lt;br /&gt;
&lt;br /&gt;
The OsRR genes express differentially in various organs examined, and also in response to light[1]. Most of the OsRR genes were expressed at relatively higher level in mature tissues (leaves and flowers).The majority of the type-A OsRR genes (OsRR2–9 and OsRR11) were expressed at various levels in roots, stems, leaves, and spikelets (Fig.5)([4]. OsRR6 was expressed mostly in roots and leaves.&lt;br /&gt;
&lt;br /&gt;
The transcript levels of OsRR2, 3, 4, 6, 7,and 9 were significantly higher in etiolated seedlings as compared to green seedlings (Fig. 6)[4].&lt;br /&gt;
[[File:fig5]]&lt;br /&gt;
&lt;br /&gt;
[[File:fig6]]&lt;br /&gt;
&lt;br /&gt;
===Evolution===&lt;br /&gt;
&lt;br /&gt;
The type-A RRs are mainly composed of a receiver domain with short N- and C-terminal extensions [2], essentially similar to the E. coli response regulator (RR) CheY involved in chemotaxis, and lack a typical output domain(3). All the OsRR proteins also contain the highly conserved Lys and two Asp residues (D-D-K) in the receiver domain (Fig. 7B, C).However, OsRR6 and OsRR7 have N-terminal extensions rich in gly and asp residues (Fig. 7C). These N- and C-terminal variable regions may play a role in their localization to different cellular compartments.&lt;br /&gt;
[[File:fig7]]&lt;br /&gt;
 No homolog of OsRR6 was found within the duplicated region, suggesting the involvement of gene loss or more localized duplications[4].  &lt;br /&gt;
&lt;br /&gt;
OsRR6 were found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2 that contains the OsRR11 gene [4](Fig. 4).&lt;br /&gt;

OsRR6 is a kind of CK-inducible type-A response regulator in rice[2].&lt;br /&gt;
==Annotated Information==&lt;br /&gt;
===Function===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is a kind of CK-inducible type-A response regulator[2].The type-A response regulators are relatively small, containing a receiver domain along with short N- and C-terminal extensions. &lt;br /&gt;
&lt;br /&gt;
The expression of a majority of OsRR genes was not significantly altered under stress, with the notable exception of OsRR6. The expression of OsRR6 gene was induced to significant levels by salt, dehydration and low temperature treatments (Fig. 1), and results were reproducible. This indicates that OsRR6 may play an important role in abiotic stress signaling in rice, besides acting as a component in cytokinin signaling[1].&lt;br /&gt;
&lt;br /&gt;
The induction of OsRR6 by different abiotic stress stimuli provides a molecular link between stress and cytokinin signaling as well[1].&lt;br /&gt;
&lt;br /&gt;
Overexpression of OsRR6 also affected the expression of CK-responsive genes[2].&lt;br /&gt;
&lt;br /&gt;
OsRR6-ox plants displayed altered morphologies and changes in CK metabolism, probably due to changes in the gene regulatory network[2].&lt;br /&gt;

&lt;br /&gt;
Future analyses of knockout or RNA interference mutants of OsRR6 will enable us to define further its possible participation in stress responses.&lt;br /&gt;
&lt;br /&gt;
===Expression===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2  (Fig. 4)[4]. &lt;br /&gt;
[[File:fig4]]&lt;br /&gt;
&lt;br /&gt;
The OsRR genes express differentially in various organs examined, and also in response to light[1]. Most of the OsRR genes were expressed at relatively higher level in mature tissues (leaves and flowers).The majority of the type-A OsRR genes (OsRR2–9 and OsRR11) were expressed at various levels in roots, stems, leaves, and spikelets (Fig.5)([4]. OsRR6 was expressed mostly in roots and leaves.&lt;br /&gt;
&lt;br /&gt;
The transcript levels of OsRR2, 3, 4, 6, 7,and 9 were significantly higher in etiolated seedlings as compared to green seedlings (Fig. 6)[4].&lt;br /&gt;
[[File:fig5]]&lt;br /&gt;
&lt;br /&gt;
[[File:fig6]]&lt;br /&gt;
&lt;br /&gt;
===Evolution===&lt;br /&gt;
&lt;br /&gt;
The type-A RRs are mainly composed of a receiver domain with short N- and C-terminal extensions [2], essentially similar to the E. coli response regulator (RR) CheY involved in chemotaxis, and lack a typical output domain(3). All the OsRR proteins also contain the highly conserved Lys and two Asp residues (D-D-K) in the receiver domain (Fig. 7B, C).However, OsRR6 and OsRR7 have N-terminal extensions rich in gly and asp residues (Fig. 7C). These N- and C-terminal variable regions may play a role in their localization to different cellular compartments.&lt;br /&gt;
[[File:fig7]]&lt;br /&gt;
 No homolog of OsRR6 was found within the duplicated region, suggesting the involvement of gene loss or more localized duplications[4].  &lt;br /&gt;
&lt;br /&gt;
OsRR6 were found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2 that contains the OsRR11 gene [4](Fig. 4).&lt;br /&gt;

OsRR6 is a kind of CK-inducible type-A response regulator in rice[2].&lt;br /&gt;
==Annotated Information==&lt;br /&gt;
===Function===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is a kind of CK-inducible type-A response regulator[2].The type-A response regulators are relatively small, containing a receiver domain along with short N- and C-terminal extensions. &lt;br /&gt;
&lt;br /&gt;
The expression of a majority of OsRR genes was not significantly altered under stress, with the notable exception of OsRR6. The expression of OsRR6 gene was induced to significant levels by salt, dehydration and low temperature treatments (Fig. 1), and results were reproducible. This indicates that OsRR6 may play an important role in abiotic stress signaling in rice, besides acting as a component in cytokinin signaling[1].&lt;br /&gt;
&lt;br /&gt;
The induction of OsRR6 by different abiotic stress stimuli provides a molecular link between stress and cytokinin signaling as well[1].&lt;br /&gt;
&lt;br /&gt;
Overexpression of OsRR6 also affected the expression of CK-responsive genes[2].&lt;br /&gt;
&lt;br /&gt;
OsRR6-ox plants displayed altered morphologies and changes in CK metabolism, probably due to changes in the gene regulatory network[2].&lt;br /&gt;
[[File:fig1]]&lt;br /&gt;
&lt;br /&gt;
Generated transgenic rice plants that overexpress OsRR6 (OsRR6-ox) by fusing its coding sequence to the rice actin1 (Act1) promoter, because this promoter generally produces much higher levels of constitutive expression in rice than the cauliflower mosaic virus(CaMV) 35S promoter. Callus transformed with Act1::OsRR6 showed severe retardation of shoot regeneration compared with callus transformed with a control vector (Fig. 2)[2].&lt;br /&gt;
[[File:fig2]]&lt;br /&gt;
&lt;br /&gt;
Moreover, each of 20 OsRR6D103E-ox independent lines was indistinguishable from plants transformed with a control vector (control plants; Fig. 3A, B).

OsRR6 is found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2  (Fig. 4)[4]. &lt;br /&gt;
[[File:fig4]]&lt;br /&gt;
&lt;br /&gt;
The OsRR genes express differentially in various organs examined, and also in response to light[1]. Most of the OsRR genes were expressed at relatively higher level in mature tissues (leaves and flowers).The majority of the type-A OsRR genes (OsRR2–9 and OsRR11) were expressed at various levels in roots, stems, leaves, and spikelets (Fig.5)([4]. OsRR6 was expressed mostly in roots and leaves.&lt;br /&gt;
&lt;br /&gt;
The transcript levels of OsRR2, 3, 4, 6, 7,and 9 were significantly higher in etiolated seedlings as compared to green seedlings (Fig. 6)[4].&lt;br /&gt;

&lt;br /&gt;
===Evolution===&lt;br /&gt;
&lt;br /&gt;
The type-A RRs are mainly composed of a receiver domain with short N- and C-terminal extensions [2], essentially similar to the E. coli response regulator (RR) CheY involved in chemotaxis, and lack a typical output domain(3). All the OsRR proteins also contain the highly conserved Lys and two Asp residues (D-D-K) in the receiver domain (Fig. 7B, C).However, OsRR6 and OsRR7 have N-terminal extensions rich in gly and asp residues (Fig. 7C). These N- and C-terminal variable regions may play a role in their localization to different cellular compartments.&lt;br /&gt;
[[File:fig7]]&lt;br /&gt;
 No homolog of OsRR6 was found within the duplicated region, suggesting the involvement of gene loss or more localized duplications[4].  &lt;br /&gt;
&lt;br /&gt;
OsRR6 were found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2 that contains the OsRR11 gene [4](Fig. 4).&lt;br /&gt;

OsRR6 is a kind of CK-inducible type-A response regulator in rice[2].&lt;br /&gt;
==Annotated Information==&lt;br /&gt;
===Function===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is a kind of CK-inducible type-A response regulator[2].The type-A response regulators are relatively small, containing a receiver domain along with short N- and C-terminal extensions. &lt;br /&gt;
&lt;br /&gt;
The expression of a majority of OsRR genes was not significantly altered under stress, with the notable exception of OsRR6. The expression of OsRR6 gene was induced to significant levels by salt, dehydration and low temperature treatments (Fig. 1), and results were reproducible. This indicates that OsRR6 may play an important role in abiotic stress signaling in rice, besides acting as a component in cytokinin signaling[1].&lt;br /&gt;
&lt;br /&gt;
The induction of OsRR6 by different abiotic stress stimuli provides a molecular link between stress and cytokinin signaling as well[1].&lt;br /&gt;
&lt;br /&gt;
Overexpression of OsRR6 also affected the expression of CK-responsive genes[2].&lt;br /&gt;
&lt;br /&gt;
OsRR6-ox plants displayed altered morphologies and changes in CK metabolism, probably due to changes in the gene regulatory network[2].&lt;br /&gt;
[[File:fig1]]&lt;br /&gt;
&lt;br /&gt;
Generated transgenic rice plants that overexpress OsRR6 (OsRR6-ox) by fusing its coding sequence to the rice actin1 (Act1) promoter, because this promoter generally produces much higher levels of constitutive expression in rice than the cauliflower mosaic virus(CaMV) 35S promoter (Zhang et al. 1991, Sentoku et al.2000). Callus transformed with Act1::OsRR6 showed severe retardation of shoot regeneration compared with callus transformed with a control vector (Fig. 2)[2].&lt;br /&gt;
[[File:fig2]]&lt;br /&gt;
&lt;br /&gt;
Moreover, each of 20 OsRR6D103E-ox independent lines was indistinguishable from plants transformed with a control vector (control plants; Fig. 3A, B). These results support the hypothesis that growth defects associated with OsRR6 overexpression are due to a requirement for phosphorylation of OsRR6[2].&lt;br /&gt;
[[File:fig3]]&lt;br /&gt;
&lt;br /&gt;
Future analyses of knockout or RNA interference mutants of OsRR6 will enable us to define further its possible participation in stress responses.&lt;br /&gt;
&lt;br /&gt;
===Expression===&lt;br /&gt;
&lt;br /&gt;
OsRR6 is found as repeats on the top arm of chromosome 4. This area of chromosome 4 is included in a segmental duplication with a region on the upper arm of chromosome 2  (Fig. 4)[4]. &lt;br /&gt;
[[File:fig4]]&lt;br /&gt;

OsRR6 was expressed mostly in roots and leaves.&lt;br /&gt;
&lt;br /&gt;
