FIG. 1.

POL and DBP trees, including GTHV. The top-scoring trees are shown based on HV POL amino acid sequences (A) and HV DBP amino acid sequences (B). The trees are presented as unrooted and in a condensed format showing genus-level groupings rather than individual species, with the multiple-branch region of each genus-level clade represented by a single heavy line. In each tree, the estimated position of the root is indicated by a filled arrowhead, calculated as the midpoint of the distance from the mean positions of branch tips in the alpha subfamily to the mean positions of branch tips in the beta and gamma subfamilies. A common scale bar is indicated for divergence (i.e., substitutions per amino acid site). Genus-equivalent labels are as follows: α1, Simplexvirus; α2, Varicellovirus; α3, Mardivirus; α4, Iltovirus; β1, Cytomegalovirus (including Muromegalovirus and Tupaia HV); β2, Roseolovirus (including porcine cytomegalovirus); β3, elephant endothelial HV; γ1, Lymphocryptovirus; γ2, Rhadinovirus. (A) The POL tree contains 44 species in addition to GTHV, distributed as follows: α1, 4 species; α2, 7 species; α3, 3 species; α4, 1 species; β1, 8 species; β2, 3 species; β3, 1 species; γ1, 3 species; γ2, 14 species. (B) The DBP tree contains 35 species in addition to GTHV, distributed as follows: α1, 4 species; α2, 6 species; α3, 3 species; α4, 1 species; β1, 7 species; β2, 2 species; γ1, 3 species; γ2, 9 species.
