植物病原镰刀菌产生的毒素种类及其危害

镰刀菌(Fusarium spp.)是多种重要农作物的病原体,不仅可造成农作物产量和品质的严重损失还可在离体培养条件下或植物寄主体内产生一系列被称为镰刀菌毒素的次生代谢产物.这些毒素一方面作为致病因子与镰刀菌对宿主植物的致病力密切相关,另一方面可导致家畜生产性能下降和相关病症的出现,进而影响农业生态系统并对人类健康造成...

Types and effects of toxins produced by plant pathogenic fungi Fusarium

As a pathogen of many important crops, Fusarium spp. can not only cause serious loss of crop yield and quality, but also produce a series of toxic secondary metabolites in vitro and in host plants, which called Fusarium toxins. On the one hand, Fusarium toxins are closely related to the pathogenicity of Fusarium to host plants as virulence factors, on the other hand, Fusarium toxins cause the decline of livestock production performance and the emergence of related diseases, which in turn affects the agricultural ecosystem and poses a threat to human health. In view of the influence of Fusarium toxins on crop production and their toxicity to livestock and human, there has been considerable studies on the types of toxin in cereal crop after infection caused by Fusarium, nevertheless, there are few studies on the types of toxin in legume forage after infection caused by Fusarium and the role of toxins in the pathogenicity of Fusarium to legume forage. This study reviewed the main toxins produced by Fusarium species which commonly cause the diseases of main food and feed crops, and the effects of these toxins on plants, livestock and humans. The prospect and significance of research on Fusarium toxins in legume forage were examined.
