Abstract:

This study was undertaken to identify homologs of NCED gene family involved in ABA accumulation in rice in response to drought stress. Results showed rapid accumulation of ABA in rice peduncles during drought and its faster degradation during rewatering. BLAST analysis using the NCED sequences of Arabidopsis led to the identification three NCED family member in rice located on chr. 3, 7 and 12. Semi-quantitative RT-PCR analysis revealed OsNCED1 is induced in rice leaves in response to drought stress   and their expression level reaches to normal upon rewatering. Further, transcript abundance of OsNCED1 was found to be correlated with ABA levels in rice leaves. The findings need further confirmation by developing over-expression/knockout mutants.
