印度是鹰嘴豆产量最高的国家，但这种作物易受植物真菌病害的影响，如核盘菌、灰葡萄孢、尖孢镰刀菌和立枯丝核菌。为了可持续的替代，研究了真菌内生菌的抗植物病原体功效。研究了椒样薄荷内生真菌的生物多样性、对上述病原菌的生防潜力及其代谢产物。从印度不同地区不同季节采集的薄荷中回收了63株真菌。利用ITS rDNA序列分析法对内生真菌进行鉴定。五氯苯甲醚揭示了季节性变化，只存在炭疽菌，D. phaseolorum，链格孢属，肉座菌Hypocrea sp.和肉座菌R.在第二个采样季节进行采样。Shannon多样性指数（H）在Mukteshwar的叶片中最高（1.253）。顶孢霉（MPM-2.1）提取物具有抗植物病原菌活性，
India is the highest producer of Cicer arietinum, however the crop is susceptible to plant fungal diseases i.e. Sclerotinia sclerotiorum, Botrytis cinerea, Fusarium oxysporum and Rhizoctonia solani. For a sustainable alternative, anti-plant pathogenic efficacy of fungal endophytes were investigated. Endophytic fungi of Mentha piperita were investigated for biodiversity, biocontrol potential towards these phytopathogens and their metabolite profiling. Sixty three fungal isolates were recovered from peppermints sampled in different seasons from distinct regions of India. Endophytic fungi were identified by ITS-rDNA sequence process. PCA divulged seasonal variability with exclusive presence of Colletotrichum sp., D. phaseolorum, Alternaria sp., Hypocrea sp. and R. oryzae in second sampling season. Shannon diversity index (H) was found to be highest in leaf (1.253) from Mukteshwar. Acremonium sp. (MPM-2.1) extract exhibited anti-plant pathogenic activity with
