DON mycotoxin biosynthesis

Gibberella zeae (Fusarium graminearum) is a fungal pathogen of major staple food crops including wheat, maize and rice. The fungus produces a range of mycotoxins including the dexoynivalenol (DON) trichothecene mycotoxin. DON contamination of food crops is a major thread to human and animal health. In wheat, but not in maize, DON was proven to be a virulence factor. Also see [http://en.wikipedia.org/wiki/Vomitoxin Wikipedia article on Vomitoxin].

Gibberella zeae (Fusarium graminearum) 为一真菌病原体，侵袭包括小麦、玉米和水稻在内的主要主食作物。该真菌能产生一系列霉菌毒素，其中包括脱氧雪腐镰刀菌烯醇（DON）三萜霉菌毒素。食品作物中的DON污染对人类及动物健康构成重大威胁。在小麦中，而非玉米中，DON已被证实为致病因素。有关呕吐毒素的详细信息，请参阅[http://en.wikipedia.org/wiki/Vomitoxin Wikipedia呕吐毒素条目]。
