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.
