Neighbor-joining (NJ) tree of the genomic sequences of GX-Tu-PV-1 and 13 other ChPV/TuPV isolates. GenBank accession numbers follow the names of the ChPV/TuPV strains. The numbers near the branches indicate the confidence level calculated by bootstrapping (n = 1,000). The length of each pair of branches represents the distance between sequence pairs. The scale bar represents 0.01-nt substitutions per site. ▲, GX-Tu-PV-1.
