The rice Os01g0646300 was reported as SLRL1 in 2005 [1] by researchers from Japan.
Contents
Annotated Information
Gene Symbol
- Os01g0646300 <=> OsSLRL1, OsGAI, OsSLRL
Function
- The rice SLR1 (SLENDER RICE 1) gene encodes a DELLA protein that belongs to a subfamily of the GRAS proteinsuper family and that functions as a repressor of gibberellin (GA) signaling.
- In rice genome databases the researchers identified two sequences homologous to SLR1: SLR1-like1 and SLR1-like2 (SLRL1 and SLRL2).
Phenotypic analysis
- Transformation of SLRL1 into the slr1 mutant rescued the slender phenotype of this mutant.
- Moreover, overexpression of 'SLRL1' in normal rice plants induced a dwarf phenotype with an increased level of OsGA20ox2 gene expression and diminished the GA-induced shoot elongation, suggesting that SLRL1 acts as a repressor of GA signaling.
- Consistent with the fact that SLRL1 does not have a DELLA domain, which is essential for degradation of DELLA proteins, a level of SLRL1 protein was not degraded by application of gibberellic acid.
Expression
- The expression of SLRL1 was positively regulated by GA at the mRNA level and occurred preferentially in reproductive organs, whereas SLRL2 was moderately expressed in mature leaf organs and was not affected by GA.
Evolution
- SLRL1 and SLRL2 contain regions with high similarity to the C-terminal conserved domains in SLR1, but lack the N-terminal conserved region of the DELLA proteins.
You can also add sub-section(s) at will.
