FIG 4.

Bayesian inference phylogenetic tree (GTR+I+G model) of “Candidatus Fokinia cryptica,” based on prokaryotic SSU rRNA gene sequences, including 23 other “Candidatus Midichloriaceae” and 9 Anaplasmataceae as an outgroup. Nucleotide columns used to calculate the tree: 1,311. Maximum likelihood bootstrap values after 1,000 pseudoreplicates and Bayesian posterior probabilities after 1,500,000 iterations are shown down to 50% and 0.5. Scale bar: 7 nucleotide substitutions per 100 positions. Ca., Candidatus.
