Unique core bacterial genera within the endophytic bacterial communities of hyperaccumulator Sedum. a Phylogenetic tree of core bacterial genera. The coloring of branches and nodes of the phylogenetic tree represents the phyla to which the taxa belong. The color of the genus names indicates the compartment where the taxa are core genera: yellow signifies core genera in both the shoot and root networks of hyperaccumulator Sedum, red indicates core genera only in the shoot network, and blue denotes core genera exclusively in the root network. b Spearman correlation between the bias-adjusted abundance of core genera in shoots and soil Cd (SCd), available soil Cd (SaCd), and plant Cd (PCd) concentrations. c Bias-adjusted abundance of core genera in shoots of different ecotypes of Sedum. d Spearman correlation between the bias-adjusted abundance of core genera in roots and SCd, SaCd, and PCd. e Bias-adjusted abundance of core genera in roots of different ecotypes of Sedum. ANCOM-BC2 was used to correct for the bias in genus abundance
