Abstract:
Rice production is severely constrained by drought stress, which causes enormous economic losses. The global climate change is evolving into a more significant problem. Enhancing agricultural yield in the drought-prone rainfed areas has become critical in light of the current and projected global food demand. Due to their complexity and multigenic regulation of drought tolerance features, breeding for drought tolerant rice varieties is a challenging task that would significantly impede present research. Drought hinders plant development and decreases crop yield. Stomatal aperture regulates CO₂ uptake and water loss to the atmosphere, and thus plays a significant role in agricultural yield gain and drought tolerance. The current study was attempted to find the allelic diversity of abiotic stress related gene, OsSRO1c in a diverse set of 3K rice genome panel. Insilico analysis of OsSRO1c sequence among the 186 rice genotypes revealed the presence of four nonsynonymous SNP. Three haplotypes (H1, H2 and H3) were identified for OsSRO1c based on four non synonymous SNPs.
