Diversity of Fungi Present in Permafrost in the South Shetland Islands, Maritime Antarctic.

摘要: We assess the fungal diversity present in permafrost from different islands South Shetland Islands archipelago, maritime Antarctic, using next-generation sequencing (NGS). detected 1,003,637 DNA reads representing, rank abundance order, phyla Ascomycota, Mortierellomycota, Basidiomycota, Chytridiomycota, Rozellomycota, Mucoromycota, Calcarisporiellomycota and Zoopagomycota. Ten taxa were dominant these being, order of abundance, Pseudogymnoascus appendiculatus, Penicillium sp., roseus, herquei, Curvularia lunata, Leotiomycetes Mortierella sp. 1, fimbricystis, Fungal 1 2. A further 38 had intermediate 345 classified as rare. The total community showed high indices diversity, richness dominance, although varied between sampling locations. use a metabarcoding approach revealed presence complex assemblage including with range ecological functions among which multiple animal, human plant pathogenic fungi. Further studies are required to determine whether identified form viable cells or propagules might be released melting other Antarctic habitats potentially dispersed more widely.
