Figure 1. Phylogenetic tree analysis of VP7 gene sequences. A total of 24 G9P[4] strains and 2 G9P[6] strains were detected in this study (indicated by black bold font). Additionally, 3 G9P[8] strains were detected in 2018 (indicated by blue bold font). The VP7 genes of 94 G8 RVAs were retrieved from the GenBank database. The genetic distance is indicated at the bottom, and the percent bootstrap support is displayed at each node when the value was 70% or larger.
Figure 2. Phylogenetic tree analysis of VP4 gene sequences. A total of 24 G9P[4] strains and 2 G9P[6] strains were detected in this study (indicated by black bold font). Additionally, 3 G9P[8] strains were detected in 2018 (indicated by blue bold font). The VP7 genes of 94 G8 RVAs were retrieved from the GenBank database. The genetic distance is indicated at the bottom, and the percent bootstrap support is indicated by the value at each node when the value was 70% or larger.
Figure 3. Simplified maximum clade credibility (MCC) drawn from representative sequences of VP7 genes. The MCC tree was constructed using a Bayesian MCMC analysis framework with a strict clock model. Reference sequences were obtained from the GenBank database (www.ncbi.nlm.nih.gov). The years of divergence of each lineage are indicated at each node. Major lineage have been collapsed for simplicity.
