Abstract

Abstract

In order to explore the diversity of fungi in the Arctic land and reveal their ecological roles, fungi were isolated and identified from 24 samples collected from Yellow River Station during the 5^th Chinese Artic Scientific Expedition in the present study. Sixty strains of fungi were totally isolated by plate spreading and streaking. More fungal species and quantity were isolated in humus than in other samples. Classification and phylogenetic analysis based on ITS rDNA showed that 28 representative fungal strains belonged to 4 classes, including Eurotiomycetes, Sordariomycetes, Dothideomycetes and Phycomycetes, and 12 genus. Geomyces was one of the most dominant genera among them. The data indicated that abundant fungal diversity existed in Arctic. The relationship between physicochemical parameters of soil and fungal diversity was explored through determination of physical and chemical properties of the representative soil. The organic carbon and nitrogen and soluble nutrient content are important factors affecting the fungal diversity in Arctic.
