Fusarium foetens, a pathogen of Begonia plants, has been recently described as a new fungal species. This Fusarium species causes a destructive vascular wilt disease which leads to the death of the plant. Moreover, Fusarium species are known to produce a huge variety of secondary metabolites such as mycotoxins and phytotoxins. Here, we studied the toxicogenic profile of one F. foetens strain, isolated from maize, employing two methods based on the use of ultra-performance liquid chromatography coupled to mass spectrometry-ion trap-time of flight detection. The mycotoxins beauvericin and fusaric acid were detected in a pure culture of F. foetens. In addition, four fusaric acid analogs (10,11-dihidroxyfusaric acid, hydroxyfusaric acid, dehydrofusaric acid, and a hydroxylated unsaturated fusaric acid analog) were tentatively identified on the basis of their accurate mass and fragmentation patterns. Therefore, these preliminary data indicate that F. foetens isolated from maize is able to produce Fusarium mycotoxins including beauvericin and fusaric acid.

镰刀菌作为霉菌毒素生产者的首次报道。

秋海棠植物的病原体镰刀菌最近被描述为一种新的真菌。该镰刀菌物种引起破坏性的维管束枯萎病，导致植物死亡。此外，镰刀菌属物种会产生各种各样的次级代谢产物，例如霉菌毒素和植物毒素。在这里，我们研究了一种从玉米中分离出的F. foetens菌株的毒理特性，该方法基于两种方法，即基于超高效液相色谱与质谱-离子阱飞行时间检测的结合。在的纯培养物中检测到白僵菌素和镰孢菌酸的真菌毒素F. foetens。此外，根据其准确的质量和片段化模式，初步鉴定了四种富斯酸类似物（10,11-二羟呋喃酸，羟基富沙酸，脱氢富马酸和羟基化不饱和富沙酸类似物）。因此，这些初步数据表明，从玉米中分离得到的F. foetens能够产生镰刀菌真菌毒素，包括金霉素和富沙酸。
