Genetic relationships among the genes of G3P[8] and G4P[8] RVs from an archival Washington, DC stool collection. The neighbor-joining phylogenetic trees were generated for each gene using the ORF nucleotide sequences. The trees are mid-group rooted for purposes of clarity, horizontal branch lengths are drawn to scale (nucleotide substitutions per base), and bootstrap values are shown as percentages for key nodes. Strain names are listed followed parenthetically by the year of specimen collection. Colored boxes indicate the genotype 1 allele designation (red, orange, green, cyan, navy, or brown). The archival G4P[8] RVs sequenced in this study are highlighted in yellow.
