Gene Details:

• MSU gene ID: LOC_Os01g70270
• RAPdb gene ID: Os01g0927600
• Gene Symbol: OsARF2 OsARF4
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• We demonstrate that OsARF2 regulates the expression of OsSUT1 through direct binding to the sugar-responsive elements (SuREs) in the OsSUT1 promoter and that OsARF18 represses the expression of OsARF2 and OsSUT1 via direct binding to the auxin-responsive element (AuxRE) or SuRE in their promoters, respectively.
• Furthermore, overexpression of OsSUT1 in the dao and OsARF2 mutant backgrounds could largely rescue the spikelets’ opening and seed-setting defects.
