小麦-赤霉病菌互作研究进展

Research Progress in Interaction Between Wheat and Fusarium graminearum

小麦赤霉病是在高温、高湿环境下由禾谷镰刀菌侵染引起的小麦真菌性病害,是对小麦生产造成威胁的主要病害之一。近年来,由于温室效应和轮作制度的共同作用,该病害频发,严重威胁小麦的产量和质量。本文对小麦赤霉病的流行特点和危害、致病机制、抗性基因及小麦-赤霉病菌互作的研究进行综述,并就目前小麦赤霉病抗病育种及抗病基因利用等方面需要解决的问题和挑战进行展望,以期为广大学者开展小麦-赤霉病菌的互作研究提供参考。

Fusarium head blight is a fungal disease caused by Fusarium graminearum that infects wheat under high temperature and humidity conditions.It is one of the main diseases that pose a threat to wheat production.In recent years,due to the greenhouse effect and rotation system,this disease has occurred frequently,seriously threatening the yield and quality of wheat.The paper provides a review of the epidemic characteristics and harms,pathogenic mechanisms,resistance genes,and the interaction between wheat and Fusarium graminearum.It also looks forward to the problems and challenges that need to be solved for resistance breeding of wheat scab and the utilization of resistance genes,in order to provide reference for scholars to study the interaction between wheat and Fusarium graminearum in future.
