An arms race: Plant pathogenesis-related endo-beta-1,3-glucanase and their inhibitor proteins produced by fungal pathogens

Plants produce pathogenesis-related (PR) proteins in response to pathogen attack. To study whether PR proteins can generate elicitor-active oligosaccharides, I examined extracts of soybean seedlings for the presence of enzymes induced by fungal infection that generate phytoalexin elicitors from mycelial walls of Phytophthora sojae f. sp. glycines (Psg), a fungal pathogen of soybean. Endo-;I have shown that the elicitors solubilized by soybean endo-;Fungal pathogens of soybean appear to have evolved a potent mechanism to protect themselves from the soybean endo-...
