Function
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. LA1 is an essential regulator of tiller angle of rice, opening a promising way for breeders to develop elite rice cultivars and other cereal crops with optimal plant architecture. LA1ΔN100 is the truncated LA1 with a deletion of amino-acid residues1-100 that 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. Rice LA1gene is responsible for the tiller-spreading phenotype of mutant plants.
Mutation
Mutations were also identified in the la1-Shiokari allele with a prostrate phenotype similar to la1-ZF802. 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. TAD1 is involved in regulating the exit of mitosis and it is indeed a functional cell-cycle switch protein homolo¬gous to Cdh1. 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.
Expression
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.
