Distribution of polymorphic sites on the VP2 gene coding region sequences (CDS) of Chinese IPNV isolates collected from different farms during 2013 through 2020. (A) Chinese genogroup I IPNV isolates. GS2017-1 isolate was used as a reference strain here. (B) Chinese genogroup V IPNV isolates. GS2020-1 isolate was used as a reference strain here. The numbers above nucleotides represent the position that polymorphic sites were located, and all of the polymorphic sites were indicated by representing the corresponding nucleotides that differ from the reference isolates.
