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。关键词:镰孢菌属真菌; 次生代谢产物; 聚酮类; 萜类; 非核糖体多肽类

Abstract:
The genus Fusarium includes a number of important plant pathogens such as Fusarium graminear-um, Fusarium moniliforme and Fusarium oxysporum, which are capable of producing many secondary metabo-lites. 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.Key words: Fusarium; secondary metabolites; polyketides; terpenes; nonribosomal peptides
