Abstract:
Rice (Oryza sativa L.) is a staple food for more than fifty percent of the world's population. Global food production must increase in order to feed the predicted 9.1 billion people by 2050. Many biotic and abiotic factors reduces the rice yield. One of such factor is reproductive stage heat stress, rice is extremely sensitive to heat stress, and rise in temperature can cause loss of around 10% to 90% of grain production. In the current study we attempted to reveal potential allelic variation in heat shock protein OsHsp17.7 (LOC_Os03g16040) contains 1 exon with transcript length of 480 bps, through in silico analysis based on the sequences available in the Rice SNP-Seek-Database. A set of 201 aus accessions from 3K rice genome project were accessed for analyzing the allelic variation. Allelic diversity analysis identified 1 SNPs in OsHsp17.7 gene sequence. In this study, two haplotypes (H1 and H2) contributed by 1 SNPs were identified for OsHsp17.7.
