Gene Details:

• MSU gene ID: LOC_Os04g56990
• RAPdb gene ID: Os04g0665600
• Gene Symbol: RLI1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• The RLI1 mutants showed reduced leaf inclination and the RLI1 over-expressors showed increased leaf inclination.
• RLI1 directly activates the downstream genes BRASSINOSTEROID UPREGULATED1 (BU1) and BU1-LIKE 1 COMPLEX1 (BC1) to control elongation of the lamina joint cells, therefore enhancing leaf inclination.
• Therefore, SPX and RLI1 form a module to regulate leaf inclination in response to external Pi availability in rice.
• RLI1 and PHOSPHATE STARVATION RESPONSE 2 function redundantly to regulate Pi starvation signaling and growth in response to Pi deficiency.
• Together, these findings indicate that the AS of RLI1 is an important and functionally conserved strategy to orchestrate Pi starvation signaling and growth to help plants adapt to Pi-limitation stress.
