Radial minimum evolution tree based on concatenated sequences of seven housekeeping genes that shows the phylogenetic positions of the species groups within the Streptococcus genus. The tree was constructed from concatenated sequences of the 95 strains from this study combined with sequences of 420 strains, primarily from the mitis group, from the study by Bishop et al. (8), and sequences extracted from the whole genomes of 40 Streptococcus strains.
