Fig 2. Phylogenomic and phylogenetic trees of the type strains of Nocardia.

(A) A phylogenomic tree was constructed based on the concatenation of 384 single-copy genes from 86 type strains. The isolated source, pathogenicity, and geographical origin are shown. (B) Phylogenetic tree based on the single gene dapb1 from 86 type strains. Each tree was constructed by the maximum likelihood method with 1000 bootstrap replicates. Rhodococcus globerulus NBRC 14531 served as an outgroup. Bootstrap values are indicated on the nodes. The colored branches indicate the five main phylogenetic groups. Black boxes indicate synonymous species.
