Figure 11. VP3-less polyomaviruses are a distinct monophyletic clade.

A neighbor-joining tree was constructed based on a MUSCLE alignment of the complete genome sequences of representatives of known polyomavirus species. Species were assigned nicknames based on common English names of host organisms (for naming key see Table S1). Host species thought to have shared a common ancestor within the past 35 million years are assigned common colors. Host animal species shown in black were excluded from the color-coding scheme. The two lobes of the apparently VP3-less clade are shaded.
