An approximately maximum likelihood phylogenetic tree of sequenced Streptomyces species.

A phylogeny was inferred for Mycobacterium tuberculosis and 120 sequenced streptomycetes based on concatenated partial sequences of aptD-gyrB-recA-rpoB. FastTree local support values (expressed as a whole number) are indicated at each node. Streptomyces albus strains are highlighted in red. The scale bar indicates 5% estimated sequence divergence.
