图3. 毒株RVA/Pig/CHN/SCLJ/C20/2019和RVA/Pig/CHN/SCYB/Y1/2019 VP4的重组序列相似性分析
纵轴表示查询毒株与其他参考毒株核苷酸序列的相似性（%）,水平轴表示核苷酸位置。A、B、C为Simplot软件分析毒株RVA/Pig/CHN/ SCLJ/C20/2019 VP7基因重组区域及基于A、B、C重组区域构建的进化树;D、E为Simplot软件分析毒株RVA/Pig/CHN/SCYB/Y1/2019 VP4基因重组区域及基于D、E重组区域构建的进化树

Fig. 3. Similarity analysis of recombinant sequence of RVA/Pig/CHN/SCLJ/C20/2019 strain and RVA/Pig/CHN/SCYB/Y1/2019 strain
The vertical axis indicates the similarity (%) of nucleotide sequences between the query strain and other reference strains, the horizontal axis indicates the nucleotide positions. The recombinant region A, B and C of VP7 gene of RVA/Pig/CHN/SCLJ/C20/2019 strain was analyzed by Simplot software, the phylogenetic tree based on recombination region A, B and C. The recombinant region D and E of VP4 gene of RVA/Pig/CHN/SCYB/Y1/2019 strain was analyzed by Simplot software, the phylogenetic tree based on recombination region D and E
