The Botrytis cinerea Crh1 transglycosylase is a cytoplasmic effector triggering plant cell death and defense response

Abstract

Crh proteins catalyze crosslinking of chitin and glucan polymers in fungal cell walls. Here, Bi et al. show that a Crh protein from the phytopathogenic fungus Botrytis cinerea acts as a cytoplasmic effector and elicitor of plant defense, and plants expressing this gene exhibit reduced sensitivity to the pathogen.
