Alignment of the nucleotide sequence and deduced amino acid for the cap gene, and Cap protein of partial strains analyzed in this study. Conserver residues are indicated by dashed lines. PCV1 is used as the majority sequence for this alignment (AY193712). a The cap gene of GXyl224 inside the red box is one wherein the stop codon mutation led to an increase in the number of nucleotides. b The major nucleotide mutation sites of Cap protein are presented within the red box
