Diversity of rhizosphere soil culturable filamentous fungi in Hainan forest ecosystem
摘要
Abstract
Hainan island in tropical China is rich in forest resources.Numerous macrofungi have been discovered on trees and ground in its forest ecosystems,while the diversity of culturable filamentous fungi in rhizosphere soil remains unclear.In this study 188 rhizosphere soil samples were collected from six national forest parks in Hainan,and 693 culturable fungal strains were isolated.Through morphological and molecular barcoding(ITS rDNA)identification,these culturable fungi were classified into 248 species belonging to 117 genera,55 families,27 orders,11 classes,and 3 phyla.Among these,26 species were previously recorded in Hainan;182 were new records for Hainan and 40 were undetermined.Ascomycota and Mucoromycota were dominant phyla.The dominant classes were,in descending order,Sordariomycetes,Mucoromycetes,Eurotiomycetes,Dothideomycetes,and Mortierellomycetes.The predominant orders included Hypocreales,Mucorales,Eurotiales,Mortierellales and Pleosporales.Leading families were Cunninghamellaceae,Nectriaceae,Aspergillaceae,Mortierellaceae,Bionectriaceae and Hypocreaceae.Dominant genera comprised Gongronella,Penicillium,Fusarium,Trichoderma,Clonostachys and Cunninghamella,with key species being Gongronella butleri only.Combined with existing literature records,total 421 current rhizosphere soil culturable fungal species in Hainan were classified into 180 genera,72 families,38 orders,18 classes,and 3 phyla.Including documented oomycetes and myxomycetes(31 species in 7 genera,3 families,3 orders,2 classes,and 2 phyla),the current compilation of Hainan rhizosphere soil fungi reaches 452 species belonging 187 genera,75 families,41 orders,20 classes,and 5 phyla.This represents the first systematic catalogue of rhizosphere soil culturable fungi in Hainan Province.关键词
