Phylogenetic tree of streptococcal chromosomal islands integrated into DNA repair genes mutL. Full genome trees are derived. In the Pyogenes group, all of which integrate into mutL, the circled members of the tree are CI found in the closely related species S. dysgalactiae subsp. equisimilis (SeqCI; nos. 9 and 13) and S. canis (ScaCI; no. 17). The SmiCI that integrates into manA in the Mitis/Pneumoniae group is boxed for identification; the remainder of the group integrates into uvrA. The members of the Anginosus and Intermedius groups integrate into mutL and have a conserved integrase gene; however, the remainder of their chromosomes is divergent, causing them to form separate phylogenetic groups. The one exception is that the S. intermedius strain F0413 SinCI (#42; underlined) is closely related to the SanCI and forms part of that group. The detailed legend for the individual members of the tree is presented in Supplemental Table 2.
