Allele level GCs of DC RVs from nonmixed specimens viewed by year of collection. The schematic illustrates the color coding of each gene for each sequenced DC RV strain based on the phylogenies shown in Fig. 1 and 3. The protein encoded by each viral gene (excluding VP7) is shown at the top. The strain name, its year of isolation, and its G genotype are shown on the left of the corresponding genome. PDAs from McDonald et al. (25, 26) are represented by rectangles colored red, green, cyan, orange, navy, or brown. NDAs are represented by rectangles colored yellow, tan, dark pink, pale pink, purple, light green, light gray, white, or dark gray. Allele designations of G3P[8] and G4P[8] DC RVs that were redefined based on the results of this study are outlined in thick lines. Strains circulating in the same year are boxed.
