Phylogeny of the family Anaplasmataceae constructed using maximum-likelihood (ML) estimations based on (A) groEL gene sequences (529 unambiguously aligned bp; best-fit approximation for the evolutionary model: T92+G), (B) on rpoB gene sequences (410 unambiguously aligned bp; best-fit approximation for the evolutionary model: GTR+G+I), (C) on gltA gene sequences (289 unambiguously aligned bp; best-fit approximation for the evolutionary model: HKY+G+I), and (D) on sucA gene sequences (563 unambiguously aligned bp; best-fit approximation for the evolutionary model: GTR+G+I). All genera of the family Anaplasmataceae, including representative species, are indicated. *, Ca. Allocryptoplasma sequences obtained in this study (GenBank accession numbers OQ724538–OQ724629). GenBank accession numbers of other sequences used in analyses are shown on the phylogenetic trees. Numbers at nodes indicate percentage support of 1000 bootstrap replicates. Only bootstrap values >70% are shown. The scale bar is in units of substitution/site.
