Genome organisation and evolutionary relationships of WPDV to other arteriviruses. a Genome features and comparison of three lineages of WPDV - WPDV-AU1, WPDV-AU2 and WPDV-NZ (GenBank accession: NC_026811). b Phylogenetic analysis of the arterivirus RdRp protein. Nodes show bootstrap values obtained from 1000 replicates. Scale bar shows the number of amino acid substitutions per site. The tree was midpoint rooted for clarity only. c Pairwise nucleotide similarities (%) among the three WPDVs
