摘要
赤霉病是影响小麦生产的重要病害。小麦赤霉菌侵染寄主后,不仅影响小麦产量和品质,感病子粒中的真菌毒素(主要为脱氧雪腐镰刀菌烯醇,Deoxynivalenol,DON)还对人畜安全造成危害,培育抗病特别是抗DON积累品种是减轻赤霉病危害的有效途径。目前,在赤霉病5种抗性类型中仅抗侵染(类型Ⅰ)和抗扩展(类型Ⅱ)的研究较为深入,随着近年来对食品安全的重视,对毒素DON积累抗性类型(类型Ⅲ)的许多研究也陆续展开。本文系统地综述了抗毒素DON积累种质资源筛选、抗性遗传和抗病基因的分子标记等方面的进展。
Fusarium head blight （FHB） caused by Fusarium graminearum,also called scab,is a destructive disease in wheat worldwide. Infection of this disease results in both yield losses and deterioration of grains quality. Particularly, contamination of mycotoxin in the infected grains is very harmful to the health of human and livestock. Deoxyni- valenol （DON） is the dominant mycotoxin form in China. Development of varieties with FHB resistance, especially DON accumulation resistance,is an efficient way to protect from the threat. Among the classified five types of FHB resistance,Type I （ resistance to the initial infection） and Type I1 （resistance to the spread of infection） have been intensively studied. Until recently, with the increasing attention on food safety issue, more and more studies were initiated on Type m （ resistance for toxin accumulation）. This paper highlighted some of the significant progresses made on screening of resistant germplasm resources, inheritance of resistance, and molecular mapping of resistant genes.
