Abstract The presented study aims to elucidate the regulatory role of Pipecolic acid (Pip) in modulating antioxidant system activity Mesembryanthemum crystallinum plants exposed Pseudomonas syringae infestation. M. , known for its semi‐halophytic nature, can transition metabolism from C 3 CAM under salt stress conditions. research encompasses plants, covering both enzymatic and low molecular weight components. findings indicate that Pip supplementation confers a beneficial effect on certain elements when are subjected induced by bacteria. Notably, during critical periods, particularly initial days post‐bacterial treatment, supplemented with exhibiting display heightened total capacity. This enhancement includes increased superoxide dismutase elevated levels glutathione proline. However, salinity‐induced CAM, where these parameters naturally higher, does not yield significant effects. These results validate hypothesis influence defence mechanisms against biotic is contingent upon metabolic state plant. Furthermore, this more pronounced than those undergoing salinity stress.
