TOXIN PRODUCING POTENTIAL OF FUSARIUM GRAMINEARUM FROM CHINA
中国小麦赤霉病菌优势种——禾谷镰刀菌产毒素能力的研究

The ability of 47 isolates of Fusarium graminearum from different provinces of China to produce mycotoxins both in liquid cultures (MOSS, MYRO and GYEP) and on rice was assessed. The toxins produced were assessed by analyzing the metabolites by GC, HPLC and GC/MS. Twenty five metabolites produced included zearalenone, butenolide and various trichothecenes. All Fusarium graminearum strains tested had a chemotype I (deoxynivalenol). Most of Chinese strains of F. graminearum from warmer regions were chemotype IA (deoxynivalenol, 3-acetyl). The strains, which were collected from the slightly cooler provinces (Henan, Shaanxi, Heilong-jiang and mountain area of Fujian) had a chemotype 1B (deoxynivalenol, 15-acetyl).
