Fungi from the genus have been reported as plant pathogens, endophytes, and saprophytes on a wide range of host plants worldwide. Their precise identification is problematic since many species can colonize a single host plant, whereas the same species can inhabit many hosts. Recently, has been proven to be a rich source of bioactive secondary metabolites. In our initial study, 40 isolates were analyzed for their metabolite production. A total of 153 compounds were identified based on their spectroscopic properties-Ultraviolet-visible and mass spectrometry. From these, 43 fungal metabolites were recognized as potential chemotaxonomic markers, mostly belonging to the drimane sesquiterpenoid-phthalide hybrid class. This group included mainly phytotoxic compounds such as cyclopaldic acid, altiloxin A, B, and their derivatives. To the best of our knowledge, this is the first report on the metabolomic studies on species complex from fruit trees in the South-Eastern Poland. The results from our study may provide the basis for the future research on the isolation of identified metabolites and on their bioactive potential for agricultural applications as biopesticides or biofertilizers.
从全球范围来看，属真菌被报道为植物病原体、内生菌和腐生菌，可寄生在多种宿主植物上。由于许多种属可以在单一宿主植物上定殖，而同一物种可以栖息在许多宿主上，因此它们的准确鉴定存在问题。最近，已经证明是生物活性次生代谢物的丰富来源。在我们的初步研究中，分析了 40 个分离物的代谢产物产生情况。根据光谱特性-紫外可见和质谱，共鉴定出 153 种化合物。其中，43 种真菌代谢产物被认为是潜在的化学分类标记物，主要属于倍半萜二菇烯-邻苯二甲酸酯杂合类。这一组主要包括植物毒性化合物，如环巴酸、阿替洛辛 A、B 及其衍生物。据我们所知，这是首次报道来自波兰东南部果树的属种复合物的代谢组学研究。我们研究的结果可能为未来对鉴定代谢物的分离及其在农业应用中的生物活性潜力（作为生物农药或生物肥料）的研究提供基础。
