Fig. 4

Phylogenetic placement of CynVolERV-A, CynVolERV-B1, CynVolERV-B2, and CynVolERV-C consensus nucleotide sequences within Retroviridae. Biogeographic distribution of species in the CynVolERV clade is also illustrated with species of the South East Asia regions being highlighted in pink, species that are distributed in Australo-Papua region being highlighted in orange, and species that can be found in both geographic regions being highlighted in green. Specific sampling information for the CynVolERV clade sequences is also illustrated. A RAxML phylogenetic tree was constructed using the GTR gamma substitution model with 20 maximum likelihood searches and 200 rapid bootstrap replicates. McERV sequence was used as an outgroup.
