Potentially mechanistic associations between rhizosphere microbes and metabolites. Hierarchical clustering heatmap shows a consistent clustering pattern within individual groups and a diverse clustering pattern between different groups (A); covariation between microbes and small molecules in A. sinensis, specifically those of differentially abundant microbes and metabolites matched against standards between GS and YS group (Spearman’s rank correlation with two-tailed nominal p values) (n = 6) (B)
