| Abstract:Sooty mold is a globally distributed plant disease caused by a complex of various epiphytic fungi, affecting a wide range of cash crops and causing substantial economic losses in agricultural production. Currently, efficient and eco-friendly control strategies against sooty mold remain insufficient. This review systematically summarizes the infection characteristics, nutritional sources, and community structure of sooty mold pathogens, and elaborates on their mechanisms underlying host interference. Specifically, these pathogens inhibit plant performance via physical shading, stomatal occlusion, heat stress induction, and metabolic pathway suppression, thereby disrupting key physiological processes including cell structure maintenance, substance metabolism, transpiration, and photosynthesis. Furthermore, this review outlines the multilayered defense systems deployed by host plants against sooty mold infection, encompassing photosynthetic compensatory adaptation, physical barrier formation, chemical defense centered on phenylpropanoid metabolism, as well as systemic immune responses mediated by pattern-triggered immunity and effector-triggered immunity. Future research directions are also discussed, aiming to provide a theoretical foundation for the development of green and efficient strategies for sooty mold management. |
