Partitioned Bayesian/ML tree topology inferred from the selected 232 genes and the 16 S rRNA gene tree of 29 species. For the concatenated tree of 232 genes, ML bootstrap supports and Bayesian posterior probabilities are shown above the branches. The stars imply newly added species in this study compared with that of Claesson et al. . Lb. delbrueckii subsp. bulgaricus 1 refers to Lb. delbrueckii subsp. bulgaricus ATCC BAA-365; Lb. delbrueckii subsp. bulgaricus 2 refers to Lb. delbrueckii subsp. bulgaricus ATCC 11842; NJ analysis under 1000 bootstrap runs of 16 S rRNA genes from the study by Ventura et al  and Kawamura et al 's study . ML bootstrap supports higher than 50 are shown above the branches.
