The amino acids sequences of Coat protein of Papaya ringspot virus isolates from South China showing the deletions (−) in the Ys, Vb, and Sm isolates, conserved DAG, WCIEN & QMKAAA domains (blue regions) and mutation sites. Ys, Vb, and Sm were the previously reported dominant strains in South China, NS1, P1, Z1, ZS1, and GZ21 are Guangdong isolates, while SD1, SD50, S1, S18, and HA1 are Hainan isolates. Different letters in the same column indicate different amino acids in that position. The yellow regions mean the glutamic acid and lysine (EK) repeat patterns, the gray and purple regions mean the different amino acids between this study’s isolates and three previously reported dominant strains in South China. Multiple alignments were performed with CLUSTALW program included in MEGA 6.
