Plant LysM receptors and fungal LysM effectors are central to plant immunity and fungal virulence. LysM receptors detect chitin fragments from fungal cell walls, triggering immune responses such as defense gene activation and reactive oxygen species (ROS) production. However, fungal pathogens secrete LysM effectors that bind chitin, preventing recognition and suppressing immunity. Some effectors also protect fungal hyphae from host chitinases, enhancing infection. The co-evolutionary arms race between plants and fungi has shaped the diversity and specificity of LysM interactions, influencing pathogen virulence and host resistance. Structural and functional studies have revealed key molecular interactions governing LysM receptor-effector dynamics. Understanding these mechanisms provides insights into plant defense strategies and fungal virulence. This knowledge can inform breeding and engineering of crops with enhanced resistance, promoting sustainable agriculture.
