Figure 1From: Nucleotide mismatches between the VP7 gene and the primer are associated with genotyping failure of a specific lineage from G1 rotavirus strainsPhylogenetic tree showing the four lineages described in genotype G1 of rotaviruses. The strains having the four mutations reported by Rahman and his colleagues are indicated by ●; the four mutations plus others at the primer binding site by ○; three out of the four mutations by ■, and three mutations plus others at the primer binding site by □. The open branches indicate one or two mutations at the primer binding site. The lineages are represented in the tree as follows: lineage I (orange), lineage II (green), lineage III (blue) and lineage IV (red).Back to article page
