华东、华中和华北城市不同生境土壤可培养真菌组成和多样性
Composition and diversity of soil culturable fungi in different urban habitats in East,Central and North China
摘要
Abstract
With the rapid development of urbanization,human activities exert significant impacts on soil microorganisms in various urban habitats.However,the composition and diversity of fungi in different urban habitats remain poorly understood.In this study,240 soil samples were collected from suburban agricultural land,hospital green spaces,sewage treatment plant green spaces,and zoo green spaces across 20 highly urbanized provinces and cities in China.Traditional culturable techniques were employed to investigate the community composition and diversity characteristics of culturable soil fungi in different urban habitats.Additionally,FUNGuild was utilized to analyze the ecological functional groups of fungi in these habitats and their functions related to potassium solubilization,phosphorus resolution,nitrogen fixation,and keratin degradation were annotated.In total,9 779 fungal isolates were screened from the 240 soil samples encompassing 3 phyla(Ascomycota,Basidiomycota,and Mucoromycota),14 classes,44 orders,101 families,250 genera,and 582 species.The α-diversity analysis of culturable fungal communities revealed significant differences among the different soil habitats.The α-diversity in the green spaces of sewage treatment plants was the highest,and that in zoo green spaces,hospital green spaces,and agricultural land subordinate.Zoo and hospital green spaces exhibited abundant and diverse populations of keratin-degrading fungi.This study provides key information for future management of urban soil microbial resources.关键词
