Bacterial communities associated with the rhizosphere and endosphere of Anthurium andraeanum L. plants and the substrate, i.e., a mixture of soil, compost, and acidic peat. Boxplots of bacterial diversity (Phylogenetic diversity, Shannon and Simpson indices) and species richness (observed 97%-OTUs and Chao1 richness estimator) (A), relative abundance of bacterial phyla and four classes of Proteobacteria (bars indicate standard deviation n = 5) (B), and principal coordinate analyses of the UniFrac distances of bacterial communities (C).
