Phylogenetic trees of Tenericutes. The maximum-likelihood phylogenetic trees were constructed by concatenated conserved proteins (a) and 16S rRNA genes (b). The bootstrap values (> 50) are denoted by the dots on the branches. The colors of the inner layer indicate the positions of the different environmental lineages and groups of Tenericutes in the trees. Sources of the environmental lineages are shown as shapes in different colors in the outer layer
