Estimation of changes in enzymatic activity due to infection of seed-borne bacterial pathogens associated with pea (pisum sativum l.) seeds

The objective of this study was to determine the differences in expression of peroxidase, polyphenol oxidase and cellulase activities against seed-borne bacterial blight and leaf spot diseases caused by Pseudomonas syringae pv. pisi and Xanthomonas pisi respectively. The seed samples of pea carrying higher incidence of the respective pathogen as well as healthy seed samples were used for enzymatic activity analysis. In the present study a significant higher enzymatic activity of peroxidase, polyphenol oxidase and cellulase were found in infected seeds as compared to healthy seeds due to infection of bacterial pathogens.
