Fig. 1. Phylogenetic trees showing the relationship of Tsukamurella strains included in this study, including 15 type and reference strains and 60 Tsukamurella isolates.
The tree was inferred from partial groEL sequence data (677 nucleotide positions of the trimmed sequence alignments respectively) by the maximum-likelihood method using the model GTR + I + G and Mycobacterium smegmatis MC2 155 (CP009494.1) as the outgroup. The scale bar indicates the estimated number of substitutions per base. Numbers at nodes indicate levels of bootstrap support calculated from 1000 trees and expressed as percentage. All names and accession numbers are given as cited in the GenBank database
