Phylogenetic tree of over 3,800 high quality and non-redundant bacterial genomes. The outer ring denotes the taxonomic group, central ring denotes the isolation source, and inner ring denotes the root-associated genomes within plant-associated genomes. Taxon names are color-coded based on phylum: green = Proteobacteria, red = Firmicutes, blue = Bacteroidetes, and purple = Actinobacteria.
