摘　　要：镰孢菌属包括禾谷镰孢、串珠镰孢和尖孢镰孢等主要的植物病原真菌,能够产生多种次生代谢产物。依据结构和合成途径,次生代谢产物可以分为聚酮类(黄色镰刀菌素、伏马毒素和玉米赤霉烯酮等)、萜类(单端孢霉烯和类胡萝卜素等)和非核糖体多肽类(铁载体等)三种主要的类型。其中,萜类中的单端孢霉烯和聚酮类的伏马毒素对人畜的健康威胁最大。本文对这些次生代谢产物的种类、作用、合成及其调节机制进行简单的概述。The genus Fusarium includes a number of important plant pathogens such as Fusarium graminearurn, Fusarium moniliforme and Fusarium oxysporum, which are capable of producing many secondary metabolites. According to structure and biosynthetic pathway, the secondary metabolites can be grouped into three classes： polyketides including aurofusarin, fumonisin and zearalenone; terpenes including trichothecene and carotenoid; nonribosomal peptides including siderophore. Among these, trichothecene and fumonisin are myco- toxins that affect human, animal health. Here we review current understanding of the classification, function, biosynthesis and regulation of the secondary metabolites produced by Fusarium fungi.
