Classical multidimensional scaling (CMDS) based on 846 protein sequences of the PCV2 capsid gene (235 amino acid residues). The blue circle indicates the exact position of the sequence that was recovered in Rancagua in 2007. Following Franzo et al. (2015) [37], genotypes a (n = 144), b (n = 499), c (n = 3), and d (n = 200) are shown in black, red, green, and yellow, respectively (Supplementary Material, Table S1).
