Figure 1.

Maximum likelihood phylogenetic trees of representative torque teno viruses. ORF1 amino acid sequences were aligned using MAFFT³¹, trees generated using IQ-TREE³³ on find best model setting with ModelFinder³⁴ (VT + F + R6 model selected) with 1000 ultrafast bootstraps³⁵ and visualized using iTOL³⁶. Genus names are indicated on the right with “-torquevirus” shortened to “TV” and the associated host species for each genus shown. The novel TTEqV2 and its genus (Mutorquevirus) and both indicated with a “black filled circle”. The tree shown here was pruned to include only the clade containing TTEqV2 and its sister clade with the whole unpruned tree available in Supplementary Material Fig. S1.
