FIG 3.

A genome-based phylogenetic tree based on 97 genome sequences of the phylum Actinobacteria. Type strain genome projects were selected as previously described (676), provided that they yielded at most 25 contigs. Phylogenetic reconstruction, including the assessment of branch support, was done using amino acid sequences according to the methods described by Meier-Kolthoff et al. (677, 678). The tree was visualized by using ITOL (679). Branch support values below 60% are not shown, but the tree generally reveals high support throughout.
