Microbial diversity and composition of A.tanguticus. (a) Microbial composition at phylum level (relative abundance of > 0.1%). Soil, rhizosphere soil; Root, root endosphere. Triangles depict statistically significant differences (Wilcoxon rank-sum test, P < 0.05). Red indicate enrichment in the root and blue indicate enrichment in the soil. (b) PCoA based on Bray–Curtis distance matrices depicting the distribution patterns of bacterial and fungal communities in rhizosphere soil and root endosphere. (c) Boxplots showing the OTU richness of bacterial and fungal communities in rhizosphere soil and root endosphere. Asterisks indicate significant differences between rhizosphere soil and root endosphere based on the Student’s t-test. The significance levels are as follows: P < 0.05, one asterisk (*); P < 0.01, two asterisks (**); P < 0.001, three asterisks (***)
