摘　　要：由禾谷镰孢(Fusarium graminearum)引起的小麦赤霉病作为小麦上重要的真菌病害之一,其能够产生脱氧雪腐镰刀菌烯醇(deoxynivalenol,DON)等真菌毒素,不仅影响小麦的品质,造成小麦严重减产,还严重威胁人畜健康。研究表明,在禾谷镰孢侵染小麦早期,效应蛋白以及DON毒素发挥着重要作用。综述总结了禾谷镰孢的致病机制、与小麦互作过程中效应蛋白和DON毒素的分子作用机制等方面的研究进展,并对未来致病基因的有效利用进行了展望,以期为今后禾谷镰孢-小麦的互作机制研究以及小麦赤霉病的防治提供理论参考。Fusarium head blight(FHB),caused by Fusarium graminearum,is one of the significant fungal diseases affecting wheat.FHB not only leads to severe yield loss in wheat but also poses a serious threat to human and animal health due to the production of mycotoxins such as deoxynivalenol(DON).Studies have shown that effectors and DON play crucial roles during the early stages of F.graminearum infection in wheat.This review summarized the pathogenic mechanisms of F.graminearum,the molecular interaction of effectors and DON during the interaction process with wheat.The paper provided an outlook on the effective utilization of pathogenic genes in the future,with the aim of providing a theoretical reference for the study of the interaction mechanism between F.graminearum and wheat,as well as the prevention and control of FHB in wheat.
