Annotated Information

Gene Symbol

  • Os02g0762600 <=> SGL1


Function

  • SG1 decreases responses to BRs and elongation of organs such as seeds and the internodes of rachis branches through decreased cellular proliferation.


Mutant

  • Overexpression of SG1 in rice produced a phenotype with short grains and dwarfing reminiscent of brassinosteroid (BR)-deficient mutants, with wide, dark-green, and erect leaves. However, the endogenous BR level in the SG1 overexpressor (SG1:OX) plants was comparable to the wild type. SG1:OX plants were insensitive to brassinolide in the lamina inclination assay.
  • SG1:OX plants, RNA interference knockdown plants that down-regulated SG1 and a related gene, SG1-LIKE PROTEIN1, had longer grains and internodes in rachis branches than in the wild type.
