摘　　要：禾谷镰孢菌(俗称禾谷镰刀菌,Fusarium graminearum)引起的小麦赤霉病是小麦生产上一种极具毁灭性的真菌病害,在世界各主要产麦国普遍发生,我国是世界上受害面积最大的国家,该病害严重威胁我国粮食生产和食品安全.解析小麦-禾谷镰孢菌之间的互作机制,挖掘有效抗病基因,对于解决小麦赤霉病这一世界难题具有重要意义.本文对禾谷镰孢菌致病机制,小麦与禾谷镰孢菌致病因子DON毒素互作机制,禾谷镰孢菌侵染与小麦识别互作机制以及寄主-病原菌基因水平转移等研究进展进行了综述.Fusasium head blight(FHB) caused by Fusarium graminearum is one of the most serious and hazardous crop diseases which occurs on most wheat-growing regions worldwide,posing a serious threat to wheat production and food security.The control of FHB requires a deeper understanding of the mechanisms underlying host plant resistance to F.graminearum and discovery of the resistance genes.This review gave a systematic summary concerning the following four aspects:(i) pathogenesis of F.graminearum,(ii) the mechanism underlying the interaction between F.graminearum pathogenic factor DON and wheat,(iii) the mechanism underlying the interaction between F.graminearum infection and wheat recognition,and(iv) host-pathogen horizontal gene transfer.
