The role of chitin detection in plant--pathogen interactions

Abstract

Despite the deployment of antifungal defence strategies, fungal diseases occur in all types of multicellular organisms. In plants, the role of fungal chitin as pathogen-associated molecular pattern that activates host defence is well established. Interestingly, plants employ homologs of the chitin immune receptors to initiate microbial symbiosis. Accumulating evidence shows that fungal pathogens developed secreted effectors to disarm chitin-triggered host immunity.
