Enzyme evolution and antioxidant defense in salt-stressed Kunthali rice: A pathway to sustainable biocatalytic solutions for crop improvement.

Kunthali (KTL), an indigenous rice variety from Tamil Nadu, India, was tested for its salt-tolerant capacity compared to commercial rice variety, IR64. Present study uncovered that KTL had a more effective response to salinity stress stimulus, as this cultivar uses reactive oxygen species scavenging mechanism through antioxidative enzymes like Superoxide dismutase, Catalase and Peroxidase. While KTL had lower levels of these enzymes compared to IR64, showed better modulation of total chlorophyll, carotenoids, anthocyanin, hydrogen peroxide, ascorbic acid, malondialdehyde, and proline contents also showed significant (p < 0.
