Figure 4: Phylogenetic analysis of the amino acid sequences of 17 new VP2 sequences from different provinces and all 8 relevant sequences (6 from complete genomes and 2 from complete CDS) currently available in GenBank.
Sequences in this study (black closed triangles) were named as previously mentioned. Sequences from GenBank were given the country name followed by the accession number. The percentages of replicate trees in which the associated taxa are clustered together in the bootstrap test (1000 replicates) are shown next to the branches. The four major groups of VP2 were identified as I, II, III, and IV.
