脱氧雪腐镰刀菌烯醇（DON）是禾谷镰刀菌复合体产生的一种真菌毒素，该复合体是重要的植物病原菌，能侵染农作物并导致严重的镰刀菌头枯病（FHB）。DON是最常见的B型青霉烯类真菌毒素，对动物和人类具有毒性作用，对食品安全构成威胁。因此，已经致力于以不同方式控制DON污染。利用木霉菌株控制DON的产生是近年来生物防治的一个热点。本研究对筛选出的8株木霉菌株进行了拮抗活性测定。在马铃薯葡萄糖琼脂（PDA）培养基上进行双重培养。木霉菌株作为潜在的拮抗菌，对F.禾谷早熟禾此外，在木霉与F.禾谷早熟禾D3G在F.首次报道了禾谷镰刀菌与木霉的互作，证明了木霉菌株在与禾谷镰刀菌竞争时，具有将DON解毒为D3G的自我保护机制。禾谷早熟禾
Deoxynivalenol (DON) is a mycotoxin mainly produced by the Fusarium graminearum complex, which are important phytopathogens that can infect crops and lead to a serious disease called Fusarium head blight (FHB). As the most common B type trichothecene mycotoxin, DON has toxic effects on animals and humans, which poses a risk to food security. Thus, efforts have been devoted to control DON contamination in different ways. Management of DON production by Trichoderma strains as a biological control-based strategy has drawn great attention recently. In our study, eight selected Trichoderma strains were evaluated for their antagonistic activities on F. graminearum by dual culture on potato dextrose agar (PDA) medium. As potential antagonists, Trichoderma strains showed prominent inhibitory effects on mycelial growth and mycotoxin production of F. graminearum. In addition, the modified mycotoxin deoxynivalenol-3-glucoside (D3G), which was once regarded as a detoxification product of DON in plant defense, was detected when Trichoderma were confronted with F. graminearum. The occurrence of D3G in F. graminearum and Trichoderma interaction was reported for the first time, and these findings provide evidence that Trichoderma strains possess a self-protection mechanism as plants to detoxify DON into D3G when competing with F. graminearum.
