Cladosporium sp. from phyloplane: a diversity evaluation on a Continental ecosystem

[摘要] The biodiversity of filamentous fungi on leaves of two genera of plants from a mixed Continental ecosystem (Český Kras, Czech Republic) was assessed. Quercus (four species) and Acer (three species) are frequent plant genera in the area. Fifteen fungal genera were identified by phenotypic methods (colony characterisation and morphology of reproductive structures). The study focused on Cladosporium, the dominant genus, but less common genera were found including Alternaria, Fusarium, Rhizopus, Penicillium, Aspergillus, Trichoderma, and Absidia. csM13 fingerprinting and ITS-ARDRA were used for genomic clustering of isolates of Cladosporium. Most Cladosporium isolates (99%) were identified as C. herbarum and C. macrocarpum. Diversity indexes and Chi-square analysis were applied to better analyse the fungal community. Continental environments are demonstrated to have some diversity of filamentous fungi, but not as large as in tropical, temperate or Mediterranean areas.
