Differences of rhizosphere soil microbial community structure and polysaccharide content of Chinese yam from different origins
Objective To reveal the differences in microbial community structure of rhizosphere soil and polysac-charide content in yam from different origins.Methods High-throughput sequencing was used to analyze the microbial community structure and predict the metabolic functions of KEGG and FUNGuild in the rhizosphere soil of yam at maturi-ty from different origins,while the polysaccharide content of yam was measured.Results Actinobacteriota,Proteobacte-ria and Firmicutes are absolutely dominant in the bacterial classification of samples from different origins.Ascomycota,Mortierellomycota and Basidiomycota are the dominant fungal groups.Chinese yam in Jiaozuo,Henan province,has the highest abundance and diversity index of bacterial community structure,and the yam in Lixian,Hebei province,have the highest abundance and diversity index of fungal community structure;the yam in Lixian,Hebei province,has the highest functional predicted abundance of both bacterial as well as fungal communities,and the dominant bacterial group is the main microbial functionally predicted group;The yam in Lixian,Hebes province has the highest polysaccharide content,followed by Wuxue,Hubei province.Conclusion Differential analysis of the polysaccharide content of yam showed that it was closely related to the structure of the rhizosphere soil microbial community,especially the metabolic function of the dominant fungal flora.
