Prediction of Fungal Diversity and Community Function in Rhizo-sphere Soil of Polyporus umbellatus from Different Production Areas in Changbai Mountain
Prediction of Fungal Diversity and Community Function in Rhizo-sphere Soil of Polyporus umbellatus from Different Production Areas in Changbai Mountain
Intersoil microorganism is an important part of the nuclear microecosystem.In order to further study the suitable area of Polyporus umbellatus in Changbai mountain as authentic medicinal materials,the fungal diversity characteristics and community composition of the rhizosphere soil of Polyporus umbellatus from different areas in Changbai mountain were analyzed,and using PacBio platform real-time sequencing(SMRT Cell),the marker gene was sequenced to determine the structure of the soil in Changbai mountain.The results showed that a total of 390 OTU were obtained from the tested samples,and the annotated fungi belonged to 24 classes,53 orders,97 families and 168 genera.At the phylum level,Ascomycota is the main dominant fungal phylum in the rhizosphere soil of Polypo-rus umbellatus from different productions areas,while at the genus level,Aspergillus is the dominant fungal genus with most soil samples.The order of the effects of soil physicochemical factors on fungal community diversity in the eight soil samples is:TP＞TK＞TN＞pH.The dominant fungi are obviously dif-ferent in different production areas in Changbai mountain,mainly dominated by ectomycorrhizal fungi.
