Species Diversity And Community Phylogenetics Of : Wood-inhabiting Fungi In The Dabie Mountains

Wood-inhabiting fungi are a group of macrofungi that grow mainly on various wood substrates.Several Wood-inhabiting fungi can decompose and utilize wood and based on the type of decay can be divided into two main groups: white rot fungi and brown rot fungi.The white rot fungi,such as Phanerochaete chrysosporium,contain lignin peroxidase,manganese peroxidase and laccase,which can be used for bioremediation of organic pollutants.Ganoderma spp.and Sanghuangporus spp.have a long history of medicinal application in China and have important medicinal values in both traditional Chinese medicine and modern pharmacology.Thus,Wood-inhabiting fungi have important ecological functions and economic values in forest ecosystems.The Dabie Mountains,in the junction of Henan,Hubei and Anhui Provinces,Central China,provide well climatic environment and favorable niches for the speciation and diversification of various life forms,but the knowledge of wood-inhabiting fungi in this region is extremely poor.In this study,the species diversity and community phylogenetics of wood-inhabiting fungi are systematically explored in the Dabie Mountains for the first time.During October 2020 and September 2021,we conducted field trips to six nature reserves,two forest parks,and two scenic areas in the Dabie Mountains to collect specimens of Wood-inhabiting fungi.A total of 175 wood-inhabiting fungi with 20 unnamed species are identified from morphological and phylogenetic perspectives on the basis of 575 specimens collected in ten sampling sites.These species belong to two classes,11 orders,42 families and 106 genera,and comprise 12 edible species,28 medicinal species,four poisonous species and seven forest pathogens.Five types of funga at the genus level are recognized for 65 genera,while another 41 genera cannot be classified in any known type.The five sampling sites in the eastern part of the Dabie Mountains have significantly higher species diversity and phylogenetic diversity of wood-inhabiting fungi than those in the western part and thus deserves priorities in terms of conservation.The community of wood-inhabiting fungi in the Dabie Mountains is generally affected by a combination of habitat filtering and competitive exclusion.In conclusion,this study not only clarified the species diversity of Wood-inhabiting fungi in Dabie Mountain area for the first time by combining morphology and phylogeny,but also obtained the resource list and host information of Wood-inhabiting fungi in Dabie Mountain area,and at the same time analyzed the community phylogenetic diversity and suggested the priority areas for conservation.
