Annotated Information
Gene Symbol
- Os07g0580500 <=> OsBZR1
Function
- A conserved function of OsBZR1 and an important role of 14-3-3 proteins in brassinosteroid signal transduction in rice.
Mutant
- Suppressing OsBZR1 expression by RNAi resulted in dwarfism, erect leaves, reduced BR sensitivity, and altered BR-responsive gene expression in transgenic rice plants, demonstrating an essential role of OsBZR1 in BR responses in rice.
- Mutation of a putative 14-3-3-binding site of OsBZR1 abolished its interaction with the 14-3-3 proteins in yeast and in vivo. Such mutant OsBZR1 proteins suppressed the phenotypes of the Arabidopsis bri1–5 mutant and showed an increased nuclear distribution compared with the wild-type protein, suggesting that 14-3-3proteins directly inhibit OsBZR1 function at least in part by reducing its nuclear localization.
