==Annotated Information==&lt;br /&gt;
===Function===&lt;br /&gt;
LAZY1 (LA1) gene regulates shoot gravitropism by which the rice tiller angle is controlled. LA1, a novel grass-specific gene, is temporally and spatially expressed, and plays a negative role in polar auxin transport (PAT). Loss-of-function of LA1 enhances PAT greatly and thus alters the endogenous IAA distribution in shoots, leading to thereduced gravitropism, and therefore the tiller-spreading phenotype of rice plants.&lt;br /&gt;
LA1 is an essential regulator of tiller angle of rice, opening a promising way for&lt;br /&gt;
breeders to develop elite rice cultivars and other cereal crops with optimal plant architecture.&lt;br /&gt;
LA1ΔN100 is the truncated LA1 with a deletion of amino-acid residues1-100 that&lt;br /&gt;
contain a predicted transmembrane domain. LA1ΔNLS refers to the LA1 truncated from amino-acid residues 286 to 312, a segment containing a putative nuclear localization signal (NLS) domain. The 996-1571 bp region of the LA1 gene was subcloned into the T-easy vector and used as templates to generate sense and antisense RNA probes.&lt;br /&gt;
Rice LA1gene is responsible for the tiller-spreading phenotype of mutant plants.&lt;br /&gt;
&lt;br /&gt;
==  Mutation==&lt;br /&gt;
Mutations were also identified in the la1-Shiokari allele with a prostrate phenotype similar to la1-ZF802.[[File:Zhangshuling1.jpg]]&lt;br /&gt;
Sequence analysis revealed a single base substitute (TGG→TGA) at the second exon of LOC_Os03g03150 in tad1, which produces a premature stop codon. LOC_Os03g03150 is the TAD1 gene and the premature mutation is responsible for the phenotypes of the tad1 mutant plant.[[File:Zhangshuling2.jpg]]&lt;br /&gt;
TAD1 is involved in regulating the exit of mitosis and it is indeed a functional cell-cycle switch protein homolo¬gous to Cdh1.[[File:Zhangshuling3.jpg]]&lt;br /&gt;
Mutation in LA1 results in a significant increase in PAT and thus impairs the IAA differential distribution in la1-ZF802, which ultimately leads to a reduced gravitropic response in the mutant shoots.[[File:Zhangshuling4.jpg]]&lt;br /&gt;
&lt;br /&gt;
== Expression==&lt;br /&gt;
LA1 is a finely regulated temporally and spatially expressed gene, and that the region of its specific expression may play an important role in controlling the rice tiller angle.[[File:Zhangshuling5.jpg]]  [[File:Zhangshuling6.jpg]]  [[File:Zhangshuling7.jpg]]&lt;br /&gt;
&lt;br /&gt;
===Evolution===&lt;br /&gt;
LA1 may represent a new type of regulating proteins that shuttle between the plasma membrane and the nucleus. Further investigations of LA1 functions will allow for a better understanding of the mechanism underlying the monocotyledonous shoot gravitropism.&lt;br /&gt;

== Function ==&lt;br /&gt;
Tillering and Dwarf 1 (TAD1) encodes a co-activator of the anaphase-promoting complex (APC/C), a multi-subunit E3 ligase. It shows increased tillers and reduced plant height. TAD1 encodes a Cdh1-type activator of APC/C, an ortholog to CCS52A in dicots. During the cell-cycle progression, TAD1 shows an oscillating expression pattern with a higher level in the G1-phase. TAD1 interacts with MOC1, forming a complex with OsAPC10 and functions as a co-activator of APC/C to target MOC1 for degradation in a cell-cycle-dependent manner. TAD1 encodes a Cdh1-type activator of APC/C, an ortholog to CCS52A in dicots.&lt;br /&gt;
&lt;br /&gt;
== Mutation==&lt;br /&gt;
&lt;br /&gt;
The tad1 mutant showed an increased tiller number, a reduced plant height, and twisted leaves and panicles[[File:Zhangyangyang1.jpg]].&lt;br /&gt;
 &lt;br /&gt;
Sequence analysis revealed a single base substitute (TGG→TGA) at the second exon of LOC_Os03g03150 in tad1, which produces a premature stop codon[[File:Zhangyangyang2.jpg]].&lt;br /&gt;
 &lt;br /&gt;
LOC_Os03g03150 is the TAD1 gene and the premature mutation is responsible for the phenotypes of the tad1 mutant plant.&lt;br /&gt;
Sequence analysis revealed that TAD1 encodes a putative cell-cycle switch protein, belonging to a Cdh1 group of APC/C co-activators, which include fission yeast SRW1/STE9, budding yeast CDH1/HCT1, Drosophila FZR1, Medicago MtCCS52A10, Arabidopsis AtCCS52A, and mouse and human Cdh1.&lt;br /&gt;
TAD1 is involved in regulating the exit of mitosis and it is indeed a functional cell-cycle switch protein homolo¬gous to Cdh1.&lt;br /&gt;
&lt;br /&gt;
== Expression ==&lt;br /&gt;
[[File:Zhangyangyang1.jpg]]&lt;br /&gt;
TAD1 is expressed ubiquitously in the examined rice organs, includ¬ing roots, shoot apices, axillary buds, internodes, nodes, and young leaves and panicles, but more abundant in young leaves, axillary buds and nodes[[File:Zhangyangyang3.jpg]].&lt;br /&gt;
TAD1 was predominantly expressed in the leaf primordia and young leaves, tiller buds, inflorescence pro¬mordia, and crown root promordia. In addition, TAD1 expression was detected in vascular bundles at the unenlon¬gated stem[[File:Zhangyangyang4.jpg]]. &lt;br /&gt;
TAD1 has an oscillated expression pattern during the cell-cycle pro¬gression, showing a higher level in the G1-phase and a lower level in the S- and G2/M-phases. TAD1 most likely controls rice tillering through regulating MOC1. The 67-amino-acid N-terminal of TAD1 appears to be essential for its interaction with MOC1. TAD1 degrades MOC1 at the G1-phase. TAD1 recruits MOC1 to APC/C, and OsAPC10 is also involved in recognizing and target¬ing MOC1 for further degradation[[File:(Zhangyangyang5.jpg]]  [[File:Zhangyangyang6.jpg]].&lt;br /&gt;
&lt;br /&gt;
== Evolution ==&lt;br /&gt;
&lt;br /&gt;
The gene provides the identification and in-depth functional characterization of a specific component of the cell-cycle machinery in higher plants that regulates agronomically important traits, tillering and plant height to facili¬tate the genetic manipulation of plant architecture and the breeding of new varieties in agriculture in the future.&lt;br /&gt;

==Annotated Information==&lt;br /&gt;
===Function===&lt;br /&gt;
LAZY1 (LA1) gene regulates shoot gravitropism by which the rice tiller angle is controlled. LA1, a novel grass-specific gene, is temporally and spatially expressed, and plays a negative role in polar auxin transport (PAT). Loss-of-function of LA1 enhances PAT greatly and thus alters the endogenous IAA distribution in shoots, leading to thereduced gravitropism, and therefore the tiller-spreading phenotype of rice plants.&lt;br /&gt;
LA1 is an essential regulator of tiller angle of rice, opening a promising way for&lt;br /&gt;
breeders to develop elite rice cultivars and other cereal crops with optimal plant architecture.&lt;br /&gt;
LA1ΔN100 is the truncated LA1 with a deletion of amino-acid residues1-100 that&lt;br /&gt;
contain a predicted transmembrane domain. LA1ΔNLS refers to the LA1 truncated from amino-acid residues 286 to 312, a segment containing a putative nuclear localization signal (NLS) domain. The 996-1571 bp region of the LA1 gene was subcloned into the T-easy vector and used as templates to generate sense and antisense RNA probes.&lt;br /&gt;
Rice LA1gene is responsible for the tiller-spreading phenotype of mutant plants.&lt;br /&gt;
&lt;br /&gt;
==  Mutation==&lt;br /&gt;
Mutations were also identified in the la1-Shiokari allele with a prostrate phenotype similar to la1-ZF802.[[File:Zhangshuling1.jpg]]&lt;br /&gt;
Sequence analysis revealed a single base substitute (TGG→TGA) at the second exon of LOC_Os03g03150 in tad1, which produces a premature stop codon. LOC_Os03g03150 is the TAD1 gene and the premature mutation is responsible for the phenotypes of the tad1 mutant plant.[[File:Zhangshuling2.jpg]]&lt;br /&gt;
TAD1 is involved in regulating the exit of mitosis and it is indeed a functional cell-cycle switch protein homolo¬gous to Cdh1.[[File:Zhangshuling3.jpg]]&lt;br /&gt;
Mutation in LA1 results in a significant increase in PAT and thus impairs the IAA differential distribution in la1-ZF802, which ultimately leads to a reduced gravitropic response in the mutant shoots.[[File:Zhangshuling4.jpg]]&lt;br /&gt;
&lt;br /&gt;
== Expression==&lt;br /&gt;
LA1 is a finely regulated temporally and spatially expressed gene, and that the region of its specific expression may play an important role in controlling the rice tiller angle.[[File:Zhangshuling5.jpg]]  [[File:Zhangshuling6.jpg]]  [[File:Zhangshuling7.jpg]]&lt;br /&gt;
&lt;br /&gt;
===Evolution===&lt;br /&gt;
LA1 may represent a new type of regulating proteins that shuttle between the plasma membrane and the nucleus. Further investigations of LA1 functions will allow for a better understanding of the mechanism underlying the monocotyledonous shoot gravitropism.&lt;br /&gt;

== Function ==&lt;br /&gt;
Tillering and Dwarf 1 (TAD1) encodes a co-activator of the anaphase-promoting complex (APC/C), a multi-subunit E3 ligase. It shows increased tillers and reduced plant height. TAD1 encodes a Cdh1-type activator of APC/C, an ortholog to CCS52A in dicots. During the cell-cycle progression, TAD1 shows an oscillating expression pattern with a higher level in the G1-phase. TAD1 interacts with MOC1, forming a complex with OsAPC10 and functions as a co-activator of APC/C to target MOC1 for degradation in a cell-cycle-dependent manner. TAD1 encodes a Cdh1-type activator of APC/C, an ortholog to CCS52A in dicots.&lt;br /&gt;
&lt;br /&gt;
== Mutation==&lt;br /&gt;
&lt;br /&gt;
The tad1 mutant showed an increased tiller number, a reduced plant height, and twisted leaves and panicles[[File:Zhangyangyang1.jpg]].&lt;br /&gt;
 &lt;br /&gt;
Sequence analysis revealed a single base substitute (TGG→TGA) at the second exon of LOC_Os03g03150 in tad1, which produces a premature stop codon[[File:Zhangyangyang2.jpg]].&lt;br /&gt;
 &lt;br /&gt;
LOC_Os03g03150 is the TAD1 gene and the premature mutation is responsible for the phenotypes of the tad1 mutant plant.&lt;br /&gt;
Sequence analysis revealed that TAD1 encodes a putative cell-cycle switch protein, belonging to a Cdh1 group of APC/C co-activators, which include fission yeast SRW1/STE9, budding yeast CDH1/HCT1, Drosophila FZR1, Medicago MtCCS52A10, Arabidopsis AtCCS52A, and mouse and human Cdh1.&lt;br /&gt;
TAD1 is involved in regulating the exit of mitosis and it is indeed a functional cell-cycle switch protein homolo¬gous to Cdh1.&lt;br /&gt;
&lt;br /&gt;
== Expression ==&lt;br /&gt;
[[File:Zhangyangyang1.jpg]]&lt;br /&gt;
TAD1 is expressed ubiquitously in the examined rice organs, includ¬ing roots, shoot apices, axillary buds, internodes, nodes, and young leaves and panicles, but more abundant in young leaves, axillary buds and nodes[[File:Zhangyangyang3.jpg]].&lt;br /&gt;
TAD1 was predominantly expressed in the leaf primordia and young leaves, tiller buds, inflorescence pro¬mordia, and crown root promordia. In addition, TAD1 expression was detected in vascular bundles at the unenlon¬gated stem[[File:Zhangyangyang4.jpg]]. &lt;br /&gt;
TAD1 has an oscillated expression pattern during the cell-cycle pro¬gression, showing a higher level in the G1-phase and a lower level in the S- and G2/M-phases. TAD1 most likely controls rice tillering through regulating MOC1. The 67-amino-acid N-terminal of TAD1 appears to be essential for its interaction with MOC1. TAD1 degrades MOC1 at the G1-phase. TAD1 recruits MOC1 to APC/C, and OsAPC10 is also involved in recognizing and target¬ing MOC1 for further degradation[[File:(Zhangyangyang5.jpg]]  [[File:Zhangyangyang6.jpg]].&lt;br /&gt;
&lt;br /&gt;
== Evolution ==&lt;br /&gt;
&lt;br /&gt;
The gene provides the identification and in-depth functional characterization of a specific component of the cell-cycle machinery in higher plants that regulates agronomically important traits, tillering and plant height to facili¬tate the genetic manipulation of plant architecture and the breeding of new varieties in agriculture in the future.&lt;br /&gt;

Sequence analysis revealed that TAD1 encodes a putative cell-cycle switch protein, belonging to a Cdh1 group of APC/C co-activators, which include fission yeast SRW1/STE9, budding yeast CDH1/HCT1, Drosophila FZR1, Medicago MtCCS52A10, Arabidopsis AtCCS52A, and mouse and human Cdh1.&lt;br /&gt;
TAD1 is involved in regulating the exit of mitosis and it is indeed a functional cell-cycle switch protein homolo¬gous to Cdh1.&lt;br /&gt;
&lt;br /&gt;

[[File:Zhangyangyang1.jpg]]&lt;br /&gt;
TAD1 is expressed ubiquitously in the examined rice organs, includ¬ing roots, shoot apices, axillary buds, internodes, nodes, and young leaves and panicles, but more abundant in young leaves, axillary buds and nodes[[File:Zhangyangyang3.jpg]].&lt;br /&gt;
TAD1 was predominantly expressed in the leaf primordia and young leaves, tiller buds, inflorescence pro¬mordia, and crown root promordia. In addition, TAD1 expression was detected in vascular bundles at the unenlon¬gated stem[[File:Zhangyangyang4.jpg]]. &lt;br /&gt;
TAD1 has an oscillated expression pattern during the cell-cycle pro¬gression, showing a higher level in the G1-phase and a lower level in the S- and G2/M-phases. TAD1 most likely controls rice tillering through regulating MOC1. The 67-amino-acid N-terminal of TAD1 appears to be essential for its interaction with MOC1. TAD1 degrades MOC1 at the G1-phase. TAD1 recruits MOC1 to APC/C, and OsAPC10 is also involved in recognizing and target¬ing MOC1 for further degradation[[File:(Zhangyangyang5.jpg]]  [[File:Zhangyangyang6.jpg]].&lt;br /&gt;

== Function ==&lt;br /&gt;
Tillering and Dwarf 1 (TAD1) encodes a co-activator of the anaphase-promoting complex (APC/C), a multi-subunit E3 ligase. It shows increased tillers and reduced plant height. TAD1 encodes a Cdh1-type activator of APC/C, an ortholog to CCS52A in dicots. During the cell-cycle progression, TAD1 shows an oscillating expression pattern with a higher level in the G1-phase. TAD1 interacts with MOC1, forming a complex with OsAPC10 and functions as a co-activator of APC/C to target MOC1 for degradation in a cell-cycle-dependent manner. TAD1 encodes a Cdh1-type activator of APC/C, an ortholog to CCS52A in dicots.&lt;br /&gt;

The tad1 mutant showed an increased tiller number, a reduced plant height, and twisted leaves and panicles[[File:Zhangyangyang1.jpg]].&lt;br /&gt;
 &lt;br /&gt;
Sequence analysis revealed a single base substitute (TGG→TGA) at the second exon of LOC_Os03g03150 in tad1, which produces a premature stop codon[[File:Zhangyangyang2.jpg]].&lt;br /&gt;

TAD1 encodes a Cdh1-type activator of APC/C, an ortholog to CCS52A in dicots. During the cell-cycle progression, TAD1 shows an oscillating expression pattern with a higher level in the G1-phase. TAD1 interacts with MOC1, forming a complex with OsAPC10 and functions as a co-activator of APC/C to target MOC1 for degradation in a cell-cycle-dependent manner. TAD1 encodes a Cdh1-type activator of APC/C, an ortholog to CCS52A in dicots.&lt;br /&gt;
&lt;br /&gt;
== Mutation==&lt;br /&gt;
&lt;br /&gt;
The tad1 mutant showed an increased tiller number, a reduced plant height, and twisted leaves and panicles[[File:Zhangyangyang.jpg]].&lt;br /&gt;
 &lt;br /&gt;
Sequence analysis revealed a single base substitute (TGG→TGA) at the second exon of LOC_Os03g03150 in tad1, which produces a premature stop codon[[File:Zhangyangyang2.jpg]].&lt;br /&gt;
 &lt;br /&gt;
LOC_Os03g03150 is the TAD1 gene and the premature mutation is responsible for the phenotypes of the tad1 mutant plant.&lt;br /&gt;
Sequence analysis revealed that TAD1 encodes a putative cell-cycle switch protein, belonging to a Cdh1 group of APC/C co-activators, which include fission yeast SRW1/STE9, budding yeast CDH1/HCT1, Drosophila FZR1, Medicago MtCCS52A10, Arabidopsis AtCCS52A, and mouse and human Cdh1.&lt;br /&gt;
TAD1 is involved in regulating the exit of mitosis and it is indeed a functional cell-cycle switch protein homolo¬gous to Cdh1.&lt;br /&gt;
&lt;br /&gt;
== Expression ==&lt;br /&gt;
[[File:Zhangyangyang1.jpg]]&lt;br /&gt;
TAD1 is expressed ubiquitously in the examined rice organs, includ¬ing roots, shoot apices, axillary buds, internodes, nodes, and young leaves and panicles, but more abundant in young leaves, axillary buds and nodes[[File:Zhangyangyang3.jpg]].&lt;br /&gt;
TAD1 was predominantly expressed in the leaf primordia and young leaves, tiller buds, inflorescence pro¬mordia, and crown root promordia. In addition, TAD1 expression was detected in vascular bundles at the unenlon¬gated stem[[File:Zhangyangyang4.jpg]]. &lt;br /&gt;
TAD1 has an oscillated expression pattern during the cell-cycle pro¬gression, showing a higher level in the G1-phase and a lower level in the S- and G2/M-phases. TAD1 most likely controls rice tillering through regulating MOC1. The 67-amino-acid N-terminal of TAD1 appears to be essential for its interaction with MOC1. TAD1 degrades MOC1 at the G1-phase. TAD1 recruits MOC1 to APC/C, and OsAPC10 is also involved in recognizing and target¬ing MOC1 for further degradation[[File:(Zhangyangyang5.jpg]]  [[File:Zhangyangyang6.jpg]].&lt;br /&gt;
&lt;br /&gt;
== Evolution ==&lt;br /&gt;
&lt;br /&gt;
The gene provides the identification and in-depth functional characterization of a specific component of the cell-cycle machinery in higher plants that regulates agronomically important traits, tillering and plant height to facili¬tate the genetic manipulation of plant architecture and the breeding of new varieties in agriculture in the future.&lt;br /&gt;

== Function ==&lt;br /&gt;
Tillering and Dwarf 1 (TAD1) encodes a co-activator of the anaphase-promoting complex (APC/C), a multi-subunit E3 ligase. It shows increased tillers and reduced plant height. TAD1 encodes a Cdh1-type activator of APC/C, an ortholog to CCS52A in dicots. During the cell-cycle progression, TAD1 shows an oscillating expression pattern with a higher level in the G1-phase. TAD1 interacts with MOC1, forming a complex with OsAPC10 and functions as a co-activator of APC/C to target MOC1 for degradation in a cell-cycle-dependent manner. TAD1 encodes a Cdh1-type activator of APC/C, an ortholog to CCS52A in dicots.&lt;br /&gt;
&lt;br /&gt;
== Mutation==&lt;br /&gt;
&lt;br /&gt;
The tad1 mutant showed an increased tiller number, a reduced plant height, and twisted leaves and panicles(Zhangyangyang).&lt;br /&gt;
 &lt;br /&gt;
Sequence analysis revealed a single base substitute (TGG→TGA) at the second exon of LOC_Os03g03150 in tad1, which produces a premature stop codon(Zhangyangyang2).&lt;br /&gt;
 &lt;br /&gt;
LOC_Os03g03150 is the TAD1 gene and the premature mutation is responsible for the phenotypes of the tad1 mutant plant.&lt;br /&gt;
Sequence analysis revealed that TAD1 encodes a putative cell-cycle switch protein, belonging to a Cdh1 group of APC/C co-activators, which include fission yeast SRW1/STE9, budding yeast CDH1/HCT1, Drosophila FZR1, Medicago MtCCS52A10, Arabidopsis AtCCS52A, and mouse and human Cdh1.&lt;br /&gt;
TAD1 is involved in regulating the exit of mitosis and it is indeed a functional cell-cycle switch protein homolo¬gous to Cdh1.&lt;br /&gt;
&lt;br /&gt;
== Expression ==&lt;br /&gt;
[[File:Zhangyangyang1.jpg]]&lt;br /&gt;
&lt;br /&gt;
TAD1 is expressed ubiquitously in the examined rice organs, includ¬ing roots, shoot apices, axillary buds, internodes, nodes, and young leaves and panicles, but more abundant in young leaves, axillary buds and nodes. TAD1 was predominantly expressed in the leaf primordia and young leaves, tiller buds, inflorescence pro¬mordia, and crown root promordia. In addition, TAD1 expression was detected in vascular bundles at the unenlon¬gated stem. TAD1 has an oscillated expression pattern during the cell-cycle pro¬gression, showing a higher level in the G1-phase and a lower level in the S- and G2/M-phases. TAD1 most likely controls rice tillering through regulating MOC1. The 67-amino-acid N-terminal of TAD1 appears to be essential for its interaction with MOC1. TAD1 degrades MOC1 at the G1-phase. TAD1 recruits MOC1 to APC/C, and OsAPC10 is also involved in recognizing and target¬ing MOC1 for further degradation.&lt;br /&gt;

TAD1 was predominantly expressed in the leaf primordia and young leaves, tiller buds, inflorescence pro¬mordia, and crown root promordia. In addition, TAD1 expression was detected in vascular bundles at the unenlon¬gated stem. TAD1 has an oscillated expression pattern during the cell-cycle pro¬gression, showing a higher level in the G1-phase and a lower level in the S- and G2/M-phases. TAD1 most likely controls rice tillering through regulating MOC1. The 67-amino-acid N-terminal of TAD1 appears to be essential for its interaction with MOC1. TAD1 degrades MOC1 at the G1-phase. TAD1 recruits MOC1 to APC/C, and OsAPC10 is also involved in recognizing and target¬ing MOC1 for further degradation.&lt;br /&gt;
&lt;br /&gt;
== Evolution: ==&lt;br /&gt;
&lt;br /&gt;
The gene provides the identification and in-depth functional characterization of a specific component of the cell-cycle machinery in higher plants that regulates agronomically important traits, tillering and plant height to facili¬tate the genetic manipulation of plant architecture and the breeding of new varieties in agriculture in the future.&lt;br /&gt;

== Function ==&lt;br /&gt;
Tillering and Dwarf 1 (TAD1) encodes a co-activator of the anaphase-promoting complex (APC/C), a multi-subunit E3 ligase. It shows increased tillers and reduced plant height. TAD1 encodes a Cdh1-type activator of APC/C, an ortholog to CCS52A in dicots. During the cell-cycle progression, TAD1 shows an oscillating expression pattern with a higher level in the G1-phase. TAD1 interacts with MOC1, forming a complex with OsAPC10 and functions as a co-activator of APC/C to target MOC1 for degradation in a cell-cycle-dependent manner.&lt;br /&gt;
&lt;br /&gt;
== Mutation: ==&lt;br /&gt;
&lt;br /&gt;
The tad1 mutant showed an increased tiller number, a reduced plant height, and twisted leaves and panicles(Fig. 1a–e).&lt;br /&gt;
 &lt;br /&gt;
Sequence analysis revealed a single base substitute (TGG→TGA) at the second exon of LOC_Os03g03150 in tad1, which produces a premature stop codon. LOC_Os03g03150 is the TAD1 gene and the premature mutation is responsible for the phenotypes of the tad1 mutant plant.&lt;br /&gt;
TAD1 is involved in regulating the exit of mitosis and it is indeed a functional cell-cycle switch protein homolo¬gous to Cdh1.&lt;br /&gt;
