Figure 8

Neighbor-Net analysis of the Phytoreo_S7 domain homologs from diverse viral lineages. The analysis was conducted under the WAG model of substitution. Scale bar corresponds to 0.2 amino acid substitutions per site. The major viral lineages are indicated. The box-like appearance in the basal branches of this phylogeny suggests regions of unresolved branches or conflicting phylogenetic signals. See Table 1 for virus names and viral protein accession numbers.
