Abstract The research was conducted to investigate comparative oxidative
damage including probable protective roles of antioxidant and glyoxalase systems
in rice (Oryza sativa L.) seedlings under salinity stress. Seedlings of two rice genotypes: Pokkali (tolerant) and BRRI dhan28 (sensitive) were subjected to 8 dSm−1
salinity stress for seven days in a hydroponic system. We observed significant variation between Pokkali and BRRI dhan28 in phenotypic, biochemical and molecular level under salinity stress. Carotenoid content, ion homeostasis, antioxidant
enzymes, ascorbate and glutathione redox system and proline accumulation may
help Pokkali to develop defense system during salinity stress. However, the activity antioxidant enzymes particularly… More >
