镰刀菌侵染植物后，除了造成严重的产量损失外，还可在植物组织中积累多种毒素。镰刀菌毒素污染是当今食品安全领域最重要的问题之一。然而，有限的信息，致病剂，病原学和真菌毒素生产的这种疾病是在中国辣椒。本研究对我国辣椒果实腐烂病病原镰刀菌进行了鉴定，并对其致病潜力进行了分析。从6个省的辣椒病株上分离到42个镰刀菌菌株，经鉴定为F. equiseti（27株）、F. solani（10株）、F. Fujikuroi（5株）。这是F.木贼F. solani和F. Fujikuroi与我国辣椒果实腐烂病相关，表明本研究中的镰刀菌种群结构与加拿大、比利时等国的调查结果有很大不同。使用成熟的液相色谱质谱法评估真菌毒素生产能力。在36种目标真菌毒素中，伏马菌素B1和B2、镰刀菌酸、白僵菌素、念珠藻素和雪腐镰刀菌烯醇在辣椒组织中检测到。此外，在甜椒果实的非定殖部分发现了一些真菌毒素，这意味着从定殖到非定殖部分的辣椒组织的迁移，这意味着在食品的非感染部分的真菌毒素污染的风险。
Apart from causing serious yield losses, various kinds of mycotoxins may be accumulated in plant tissues infected by Fusarium strains. Fusarium mycotoxin contamination is one of the most important concerns in the food safety field nowadays. However, limited information on the causal agents, etiology, and mycotoxin production of this disease is available on pepper in China. This research was conducted to identify the Fusarium species causing pepper fruit rot and analyze their toxigenic potential in China. Forty-two Fusarium strains obtained from diseased pepper from six provinces were identified as F. equiseti (27 strains), F. solani (10 strains), F. fujikuroi (five strains). This is the first report of F. equiseti, F. solani and F. fujikuroi associated with pepper fruit rot in China, which revealed that the population structure of Fusarium species in this study was quite different from those surveyed in other countries, such as Canada and Belgium. The mycotoxin production capabilities were assessed using a well-established liquid chromatography mass spectrometry method. Out of the thirty-six target mycotoxins, fumonisins B1 and B2, fusaric acid, beauvericin, moniliformin, and nivalenol were detected in pepper tissues. Furthermore, some mycotoxins were found in non-colonized parts of sweet pepper fruit, implying migration from colonized to non-colonized parts of pepper tissues, which implied the risk of mycotoxin contamination in non-infected parts of food products.
