The sequence alignment based on amino acids of capsid protein. 34 PCV3 strains isolated in this study and 3 reference strains were aligned by clustal W method in MEGA6.0 software. All the isolates were cluster into three subgroups, subgroup 1 (green), subgroup 2 (blue), subgroup 3 (yellow). The potential genetic marker were showed in the black rectangles
