Co-occurrence patterns of the root bacterial community of A.tanguticus. (a) Co-occurrence networks for root bacterial community based on Spearman’s correlations (r > |0.5|, FDR-corrected P < 0.05). The red and blue dots represent core root microorganisms and others, respectively. (b) Node-level network topological features of different microbial taxa, specifically the degree, betweenness centrality, closeness centrality and eigenvector centrality. Statistical significance was determined by the Wilcoxon rank-sum test. The significance levels are as follows: P < 0.05, one asterisk (*); P < 0.01, two asterisks (**); P < 0.001, three asterisks (***)
