Annotated Information
"Figure 1.(from reference[1]）."
Gene Symbol
- Os01g0274800 <=> OsSG1, Sg1
Function
- SG1, encodes a novel protein that is conserved among angiosperms.
- SHORT GRAIN1 (SG1) controls the elongation of both grains and internodes in rachis branches.
- SG1 decreases organ elongation by decreasing cell proliferation and also decreases responses to BRs and elongation of organs such as seeds and the internodes of rachis branches through decreased cellular proliferation[1]
Phenotypic analysis
- 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.
Expression
- During vegetative growth,SG1 was preferentially expressed in the roots.
- During reproductive growth, SG1 was strongly expressed in the young panicles (0.3–1 cm in length), and expression then gradually decreased as the panicles matured.
- In the developing panicles, SG1 was expressed most strongly in the spikelets and the basal parts of rachis and rachis branches.
Evolution
- SG1 does not share significant identity with any proteins of known function.
- However, SG1 and related proteins comprise a family that is conserved among monocots and dicots. The rice genome encodes two SG1-related proteins (Os02g0762600 and Os08g0474100) that have 49% to 53% sequence identity with SG1.[1]
