The relationship between root endophytic microbial of plant species and soil properties in different patches of alpine meadow

Plants do not live alone as single entities but are closely associated with an incredible diversity of bacteria, fungi and other organisms. To explore the advantages of endophytes in controlling ecosystem responses to plant community succession, in this study, the Illumina MiSeq high-throughput sequencing technology was applied to characterize root endophytic microbials community structure composition and diversity variation in different patches of degraded alpine meadow. The relationship between root endophytic microbials of plant species and soil properties was analyzed. The results showed that the soil property values all decreased after K. humilis dominated alpine meadow community was replaced by A. tenuifolia, L. virgaurea and P. kansuensis dominated patches. Root endophytic fungi were little affected by soil pH and soil properties. Unlike the fungi, the plant species of root endophytic bacteria have been affected by different dominant plants or soil properties availability. Root endophytic bacteria were species richness, greater diversity and well correlated with soil pH and soil properties in phyla level. Positive and negative associations in the root endophytic microbiome were observed. Exploring and finding the method of plant-microbial joint restoration in the ecological restoration, so as to provide reference for the further study of plant endophytic microbial resources in alpine meadow.
