Wheat is a most important food crop worldwide. Wheat is reported to be susceptible to a variety of fungi, which could induce huge economic losses and the contamination of potential mycotoxins could bring serious toxic effects. In this work, UV-C irradiation treatment on Fusarium infected wheat seeds during germination was investigated. The results show that UV-C irradiation treatment could promote the germination rate of wheat in inoculated seeds samples. In addition, UV-C treatment could significantly inhibit Fumonisins and Beauvericin mycotoxins production. However, Enniatins production in inoculated wheat seed samples are enhanced in long-term UV-C irradiation treatment samples. Metabolites of Fumonisins, Beauvericin, and Enniatins are evaluated with major metabolic pathways including methylation/demethylation, hydrogenation/dehydrogenation, oxidation/deoxidation, and acetylation. In conclusion, short time UV treatment for 15 min is the best for the inhibition of target Fusarium mycotoxins production, which will be benefit for the improvement of the quality and safety of wheats.
小麦是全球最重要的粮食作物。据报道，小麦易受多种真菌侵害，这可能导致巨大的经济损失，而且潜在的霉菌毒素污染会带来严重的毒性作用。在这项研究中，对发芽过程中受镰刀菌感染的小麦种子进行了紫外线-C照射处理。结果表明，紫外线-C照射处理可提高接种种子样本中小麦的发芽率。此外，紫外线-C处理可显著抑制伏马毒素和白僵菌素霉菌毒素的产生。然而，在长期紫外线-C照射处理的样本中，接种小麦种子样本中的恩镰孢菌素产量会增加。对伏马毒素、白僵菌素和恩镰孢菌素的代谢产物进行了评估，其主要代谢途径包括甲基化/去甲基化、氢化/脱氢、氧化/脱氧和乙酰化。总之，15分钟的短时间紫外线处理最有利于抑制目标镰刀菌霉菌毒素的产生，这将有助于提高小麦的质量和安全性。
