Phylogram representing relationships between the sequences encoded by the poxvirus DNA polymerase gene from different host species. This unrooted phylogenetic tree was constructed using the maximum parsimony method based on amino acid sequences. The results of the bootstrap analysis (500 replications) are indicated at the tree nodes. Each sequence name is composed of the virus name and the GenBank accession number. Poxvirus from walrus is highlighted in bold.
