Comparative study of rhizosphere soil fungal community structure among different plants in Tomur Peak,Xinjiang
摘要
Abstract
The aims of this study were to explore the structure and function of the rhizosphere fungal community in different plant species growing around Tomur Peak,and to determine how these characteristics contribute to the maintenance of ecosystem stability.High-throughput sequencing technology was used to detect differences in fungal community structure in the rhizosphere soil among four plants;Codonopsis javanica,Poa annua,Geranium wilfordii,and Medicago sativa.Correlations between soil physicochemical properties and fungal community structure were also analyzed.The results showed that Shannon's index and Simpson's index,indicators of rhizosphere soil fungal diversity,were higher in C.javanica than in the other plant species.A non-metric multidimensional scaling analysis showed that the fungal community structure of C.javanica differed from that of the other plant species.Across all samples,the dominant fungal phyla in the rhizosphere soil were Ascomycota,Mortierellomycota,Basidiomycota,and Chytridiomycota.Mortierellales and Hypocreales were the dominant fungal orders,but their relative abundance varied among the four plant species.Among all samples,the dominant nutritional pattern of fungi was saprotrophic(32.1%-52.5%),followed by symbiotrophic in rhizosphere soil of C.javanica(9.3%);pathotrophic-saprotrophic in rhizosphere soil of G.wilfordii(4.1%),and pathotrophic in rhizosphere soils of P.annua and M.sativa(8.3%and 15.8%,respectively).Undefined saprophytic fungi was the dominant functional group(28.6%-44.2%),but the proportions of other functional groups differed among plant species.In conclusion,we detected significant differences in the structure and composition of rhizosphere soil fungal communities among plant species.These results provide a theoretical basis for understanding the environmental adaptation strategies of alpine plants and for designing ecological restoration strategies for this region.关键词
