Figure 1.
The 10 conserved TFs in Waddlia chondrophila and their orthologues in the PVC superphylum. Presence (blue) or absence (white) of the 10 TFs in the PVC superphylum. The % of identity, compared with W. chondrophila, is indicated in each square. The proteins are indicated on the top, organisms on the left and the family (black) and the phylum (blue) on the right. Organisms are ordered on the basis of the phylogenetic tree performed with the maximum likelihood method using the 158 core genes. The topology of the Chlamydiae phylum derived from the concatenation of the 158 core genes is similar to what is already known (Pillonel et al, 2015). Euo, HrcA and DnaA3 are only present in the Chlamydiae. PhoB, AtoC and NrdR are conserved in the PVC superphylum. ParB is not present in Simkania negevensis and NrdR is not present in Parachlamydia acanthamoebae.
