Figure 3
Phylogenetic tree based on the deduced amino acid sequence of ORF5.The bootstrap consensus tree is shown. The sequence downloaded from GenBank had a suffix “ORF5.” The representative strains were labeled with “black triangle” and the vaccine strains were labeled with “black diamond.” The bootstrap values were shown close to the branches.
