The Genetic Diversity and Interspecific Transmission of Circovirus in Rhizomys sinensis in Guangdong, Southern China

Figure 4

Multiple sequence alignment of Cap protein amino acid sequences from PCV2d strains of diverse origins. The alignment includes the RS-origin PCV2 strain (RtRs-PCV2/2020) and the other 16 reference PCV2d strains. The blue areas denote the unique motifs in PCV2d Cap protein sequences. Antibody recognition domains, heparin sulfate-binding receptor domain, and immunodominant decoy epitope are indicated by red, purple, and blue boxes, respectively. The red squares indicate the strain of this study.
