摘要：
The fungal cell wall, which is mainly composed of polysaccharides, is a major source of pathogen-associated molecular patterns (PAMPs). Because PAMPs recognition activates immunity in plants, successful pathogens have developed immune-evasion strategies. Studies of various fungal rice pathogens indicated that masking the cell wall surface with alpha-1,3-glucan, a polysaccharides that is not degradable by plants, is a fungal PTI evasion strategy. Interestingly, accumulation of alpha-1,3-glucan at the surface was specifically observed in presence of plants or plant factor(s). Since the surface alpha-1,3-glucan protected the fungal cell wall from digestive enzymes and interfered with PAMPs generation by host enzymes, fungal alpha-1,3-glucan is a potential target for plant protection strategies.
