Diversity and structure of fungal endophytes in some climbers and grass species of Malnad region, Western Ghats, Southern India

[摘要] A total of 3,732 fungal isolates were recovered from 6000 leaf segments incubated from ten medicinal climbers and grass species during the monsoon, winter and summer seasons. The fungi comprised Ascomycota (22.8%), Coelomycetes (17.7%), Hyphomycetes (44.7%), Zygomycetes (0.3%) and mycelia sterilia (14.5%). Alternaria alternata, Chaetomium globosum, Cladosporium cladosporioides, C. hebarum, Curvularia lunata, Gliocladium roseum, Nigrospora shaerica, and Phyllosticta spp. were frequently isolated. Colonization frequency (%) differed significantly between the seasons (F=5.35). The colonization rate was higher during the winter than in the monsoon and summer seasons.
