ACETYL SALICYLIC ACID MEDIATED INDUCTION OF PR-PROTEINS IN GROUNDNUT
Acetyl salicylic acid (ASA) is acetyl derivative of salicylic acid. ASA is involved in biotic and abiotic stress tolerance in plants. A field experiment was, therefore conducted to evaluate the possible involvement of lipid peroxidation and antioxidative enzymes in ASA mediated induction of pathogenesis related proteins (PR-protein) in groundnut. The results showed that all the applied concentrations of ASA increased lipid peroxidation, activities of peroxidase and superoxide dismutase. In particular, 100 ppm ASA profound better influence. In contrast to it decreased activity of catalase enzyme was recorded with ASA treatments. Application of 5 and 100 ppm ASA was found to be highly effective in PR-protein induction in groundnut. The detected protein bands are generally belonging to the PR-1 and PR-5 families having chitinase and glucanase activity. The results relevant to antioxidative enzymes and protein profile indicated that ASA mediated induction in lipid peroxidation could act as translocated signal that may elevate PR- protein induction and establish systemic acquired resistance (SAR) in groundnut.
