The promoters of OsGLP genes exhibited differentially methylated sites under drought and salt stress in rice cultivars

DNA methylation at cytosine residues governs the regulation of stress responsive genes in plant for self-protection against various environmental abiotic stresses. Here, we analyzed epigenetic consequences drought and salinity on dynamics promoter regions Germin-like protein rice (Oryza sativa). The bisulfite sequencing technique was employed to identify differential status selected three OsGLP (OsGLP4-1, OsGLP8-10 OsGLP8-12) leaves roots two elite Indica cultivars (tolerant KS282 sensitive Super Basmati) under salt stress. Our results identified cultivar, tissue stress-dependent differentially methylated residues, however, extent found be different depending upon CGN, CHG CHH sequence contexts. Among all genes, region OsGLP8-12 detected with most heavily significantly sites types variety, or conditions. However, no site OsGLP4-1. Moreover, OsGLP8-12, several response treatments were either near within cis-regulatory elements (CREs) related This indicated association between which might a key mechanism associated their stresses contrasting cultivars.
