FIG 6.

Phylogenetic relationship between poxvirus species indicates that A26 is not ancestral to the chordopoxviruses. Vinyl plot depicting the phylogenetic relationship between representative poxvirus species based on the orthologs of the E9 gene. The inner ring depicts a maximum likelihood tree based on the JTT model of amino acid evolution (see Table 1 for sequence accession numbers). Branch lengths are not to scale. Clade I chordopoxviruses are shown in pink, and clade II chordopoxviruses are in yellow. The outer ring depicts a list of representative virus species color-coded based on genera.
