Deciphering the transcriptional activities of pathogenicity genes is critical to understand pathogenesis mechanisms of Phytophthora melonis, a devastating pathogen of cucurbits. In this study, we have performed comparative proteomics among P. melonis mutants to evaluate the interacting pathogenicity proteins. Structural characterization of all detected proteins discovered the physicochemical factors behind their pathogenic behavior. Results revealed that gamma radiations have an extreme potential to mutate P. melonis spores, and can be a safe alternative of chemical...
