Gene Details:

• MSU gene ID: LOC_Os05g33810
• RAPdb gene ID: Os05g0408200
• Gene Symbol: OsSPL9
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Overexpression of OsSPL9 enhances accumulation of Cu in rice grain and improves its digestibility and metabolism.
• Moreover, natural variation in the MIR528 promoter region caused differences in miR528 expression among rice varieties, potentially due to differences in the binding strength of the transcription factor OsSPL9.
• OsSPL9 was highly expressed in the early developing young panicles, consistent with its function of regulating panicle development.
• By combining expression analysis and dual-luciferase assays, we further confirmed that OsSPL9 directly activates the expression of RCN1 (rice TERMINAL FLOWER 1/CENTRORADIALIS homolog) in the early developing young panicle to regulate the panicle branches and GNP.
• OsSPL9 Regulates Grain Number and Grain Yield in Rice.
