Figure 1. Phylogenetic tree of four novel HPV types among Gammapapillomaviruses.

Figure 1

Maximum likelihood tree was estimated by PhyML v3 30. ModelTest v3.7 29 reported GTR+I+G substitution model as the best fit model. HPV16, an α-HPV type (underlined) was used as the out group for the tree analysis, and the tree was based on L1 sequences of 50 gamma HPV reference clones (www.hpvcenter.se). Nodes having bootstrap values less than 0.7 were labeled with an asterisk, and new HPV types identified in this study were marked by boxes.
