Xanthomonas vesicatoria potential bacteria responsible for bacterial spot a major seed borne disease in many plants. This study focused on the time course of defense related enzyme like peroxidase (PO), polyphenol oxidase (PPO) in bacterial spot pathogenesis of Capsicum annuum. The results indicate, that increased peroxidase and polyphenol oxidase level in chilli, upon treatment with Xanthomonas vesicatoria than control. The increase peroxidase activity was about 14.1 nm/mg protein at 25h and 14.5nm/mg protein at 30h in case of polyphenol oxidase. The subsequent decrease in activity of both the enzymes was observed. The increased activity in chilli seeds may be due to the accumulation of phenols, were it acts as a cofactor of enzyme and hence one of the important biochemical parameters for disease resistance.
