摘　　要：核盘菌(Sclerotinia sclerotiorum(Lib.)de Bary)是世界性的死体营养型植物病原真菌,寄主范围极广,所引起的大豆和油菜等菌核病会导致农业生产的巨大经济损失.核盘菌致病机制复杂,不仅具有直接杀死细胞的典型死体营养阶段,也包含需抑制植物免疫的短暂活体营养期.核盘菌具有种类繁多的致病因子,包括介导侵染结构形成或抗逆能力的关键调控因子、降解植物细胞组分的水解酶、草酸、诱导植物细胞死亡或抑制植物免疫的效应蛋白等.综述核盘菌侵染模型,总结各种致病因子,尤其是效应蛋白在核盘菌致病中的作用,并结合最新研究结果对核盘菌致病新机制进行展望,为作物菌核病的防控提供理论依据.Sclerotinia sclerotiorum(Lib.)de Bary is a worldwide and necrotrophic phytopathogenic fungi with a wide host-range.Sclerotinia stem rot(SSR)caused in soybean and rapeseed by S.sclerotiorum has caused huge economic losses to agricultural production.The pathogenic mechanism of S.sclerotiorum is complicated,which not only has a necrotrophic phase that directly kills cells,but also includes a short biotrophic phase that needs to suppress plant immunity.S.sclerotiorum has a wide variety of pathogenic factors,including key regulatory factors that mediate the formation of infection structure or stress resistance,hydrolytic enzymes that degrade plant cell components,oxalic acid,effector that induce plant cell death or inhibit plant immunity,etc.We have reviewed the infection model of S.sclerotiorum,summarized the roles of various pathogenic factors,especially effector proteins,in the pathogenesis of S.sclerotiorum.Combined with the latest research,we have prospected the new pathogenic mechanism of S.sclerotiorum,providing theoretical basis for the prevention and control of crop Sclerotinia diaease.
