The fungal-specific β-glucan-binding lectin FGB1 alters cell-wall composition and suppresses glucan-triggered immunity in plants

Abstract

β-glucans derived from fungal cell walls can trigger immune responses in animals, yet their roles in plant-fungal interactions are less well known. Here, Wawraet al. show that the FGB1 proteins, secreted by the fungal endophyte P. indica, can alter fungal cell wall composition and suppress immune responses in plants.
