Functional profiles of tobacco microbiomes. A Nonmetric multidimensional scaling (NMDS) ordination analysis based on Bray–Curtis distance matrices of the KEGG ontology annotations, showing that the CNS-induced tobacco microbiome significantly differed from the control microbiome (n = 48). B Boxplot of the functional diversity of microbiomes in four compartments. Asterisks above the boxes indicate a significant difference (P < 0.01). C Heatmap exhibiting the relative abundance of functional genes associated with plant growth–promotion functions. All genes associated with plant growth–promotion functions are listed in Additional file 2: Table S5. The four compartments are bulk soils (BS), rhizosphere (RS), root endosphere (R), and stem endosphere (S)
