Phylogenetic relations among felid species and their papillomaviruses

Copyright information:Taken from "Ancient papillomavirus-host co-speciation in Felidae"Genome Biology 2007;8(4):R57-R57.Published online 12 Apr 2007PMCID:PMC1896010. Co-evolutionary relationships revealed by the feline multigene (left) and papillomavirus (PV) complete coding genome (right) phylogenetic trees. Identical tree topologies were reconstructed by using both maximum likelihood (ML) and Bayesian methods for all data sequences from Johnson and coworkers [12] and for the amino acid translation of the concatenated PV genes. Bayesian posterior support values (bold) and ML bipartition values for relationships are shown on the branches. The scale bars indicate the genetic distance (nucleotide substitutions per site). Scientific names and branches in the host phylogenetic tree are color coded to depict recent and historic zoogeographic regions shown on the map (Oriental, Palearctic, Ethiopian, Neotropical, and Nearctic), as inferred by Johnson and coworkers [12] from current distributions, fossil records, and phylogenetic analysis. Branches in black reflect either less certain historical interpretations or geographic distributions beyond one. For the viral phylogenetic tree, the same color code is used for the abbreviated virus name, depicting the geographical region from which the respective virus was isolated. Outgroups are (Pli) and (Cfe) in the host tree, and PV type 1 (PlPV1) and canine oral PV (COPV) in the virus tree. Branch length correlation (nucleotide substitutions per site) for the feline and PV phylogenetic trees. Outgroup lineages were excluded from this analysis. FdPV1, PV type 1; LrPV1, PV type 1; PcPV1, PV type 1; PlpPV1, PV type 1; UuPV1, PV type 1.
