Gene Symbol
- Os01g0165000 <=> OsDREB2A, OsDREB2a, ERF40, OsERF#040, OsERF040, OsERF40
Function
- Stress responsive transcriptional regulation is an adaptive strategy of plants that alleviates the adverse effects of environmental stresses.
- The ectopic overexpression of Dehydration-Responsive Element Binding transcription factors (DREBs) either in homologous or in heterologous plants improved stress tolerance indicating the DRE/DREB regulon is conserved across plants.
- OsDREB2A confers stress tolerance in homologous rice system that failed in the heterologous Arabidopsis system earlier.
Phenotypic analysis
- 30 transgenic T0 rice plants overexpressing OsDREB2A were generated by researchers which were devoid of any growth penalty or phenotypic abnormalities during stressed or non-stressed conditions.
- Integration of T-DNA in the rice genome and stress inducible overexpression of OsDREB2A had occurred in these transgenic lines. Functional analyses of T 1-3 and T 1-10 lines revealed significant tolerance to osmotic, salt and dehydration stresses during simu- lated stress conditions with enhanced growth performance as compared to wild type.
