Maximum likelihood tree of Wolbachia genomes based on 256 orthologous genes. These genes are single-copy coding genes present in each of the 19 genomes and include 183,819 nucleotide positions of which 25,996 are parsimoniously informative. The general time reversible base substitution model (GTR + F + R2) was used to produce the tree, supported by 1000 bootstrap repetitions. wCer genomes are shaded grey
