Gene Details:
- MSU gene ID: LOC_Os11g29840
- RAPdb gene ID: Os11g0490600
- Gene Symbol: LA1 LAZY1
- Genome: MSU7 , IRGSP-1.0
- Species: Oryza sativa
Functional Descriptions:
- We show that LA1, a novel grass-specific gene, is temporally and spatially expressed, and plays a negative role in polar auxin transport (PAT).
- Here we report the cloning of the LAZY1 (LA1) gene that regulates shoot gravitropism by which the rice tiller angle is controlled.
- Loss-of-function of LA1 enhances PAT greatly and thus alters the endogenous IAA distribution in shoots, leading to the reduced gravitropism, and therefore the tiller-spreading phenotype of rice plants.
- LA1 is able to rescue the tiller angle and shoot gravitropism defects observed in LA1-SN.
- LA1 is required to regulate the expression of auxin transporters and signaling factors that control shoot gravitropism and tiller angle.
- The results show that LA1 may be involved in the nucleosome and chromatin assembly, and protein-DNA interactions to control gene expression, shoot gravitropism, and tiller angle.
- Our results provide new insight into the mechanisms whereby LA1 controls shoot gravitropism and tiller angle in rice.
