LEfSe and correlation analyses of endophytic communities in different parts of C. pilosula. a, c Cladogram of remarkably enriched bacterial and fungal taxa, respectively. Phylum, class, order, family, and genus levels are listed in order from the inside to the outside of the cladogram. Small circles with different colors in the diagram denote enriched taxa, while yellow circles represent the taxa with no remarkable differences in different parts. Each circle diameter is proportional to the taxon’s abundance. b and d Enriched bacterial and fungal taxa that reached a linear discriminant analysis (LDA) significance threshold of 2.5 or greater, respectively, and correlation heatmap of the relationship between the abundance of enriched bacterial and fungal taxa, respectively, and the contents of pharmacological components. Asterisks denote significant correlation based on Spearman’s analysis (**P < 0.01; *P < 0.05). CK untreated group, DT drought treatment group
