Five sections have members that are established agricultural pests and producers of different metabolites, threatening global food safety. Most of these pathogenic species have been isolated from almost all major biomes. The soil remains the primary habitat for most of these cryptic fungi. This review explored some of the ecological attributes that have contributed immensely to the success of the pathogenicity of some members of the genus over time. Hence, the virulence factors of the genus , their ecology and others were reviewed. Furthermore, some biological control techniques were recommended. Pathogenic effects of species are entirely accidental; therefore, the virulence evolution prediction model in such species becomes a challenge, unlike their obligate parasite counterparts. In all, differences in virulence among organisms involved both conserved and species-specific genetic factors. If the impacts of climate change continue, new cryptic species will emerge and mycotoxin contamination risks will increase in all ecosystems, as these species can metabolically adjust to nutritional and biophysical challenges. As most of their gene clusters are silent, fungi continue to be a source of underexplored bioactive compounds. The World Soil Charter recognizes the relevance of soil biodiversity in supporting healthy soil functions. The question of how a balance may be struck between supporting healthy soil biodiversity and the control of toxic fungi species in the field to ensure food security is therefore pertinent. Numerous advanced strategies and biocontrol methods so far remain the most environmentally sustainable solution to the control of toxigenic fungi in the field.
五个分类单元的成员是已确定的农业害虫和不同代谢产物的生产者,对全球食品安全构成威胁。这些致病物种大多已从几乎所有主要生物群落中分离出来。土壤仍然是这些隐性真菌大多数的主要栖息地。本综述探讨了随着时间的推移,一些生态属性对该属某些成员致病性的成功起到了极大的促进作用。因此,对该属的毒力因子、它们的生态学及其他方面进行了综述。此外,还推荐了一些生物防治技术。该属物种的致病作用完全是偶然的;因此,与专性寄生菌不同,预测此类物种的毒力进化模型成为一项挑战。总体而言,生物体之间毒力的差异涉及保守和物种特异性的遗传因素。如果气候变化的影响持续下去,新的隐性物种将会出现,并且所有生态系统中霉菌毒素污染风险将会增加,因为这些物种能够在代谢上适应营养和生物物理挑战。由于它们的大多数基因簇是沉默的,真菌仍然是生物活性化合物未得到充分探索的来源。《世界土壤宪章》认识到土壤生物多样性对支持健康土壤功能的相关性。因此,在支持健康土壤生物多样性与控制田间有毒真菌物种以确保粮食安全之间如何取得平衡的问题是恰当的。迄今为止,众多先进策略和生物防治方法仍然是控制田间产毒真菌最具环境可持续性的解决方案。
