Figure 4. Phylogenetic analyses based on (A and B) whole genome, (C) major capsid protein sequence, and (D) terminase large subunit. (A) Comparative genomics (n = 91) was performed using VICTOR web server with settings recommended for prokaryotic viruses. Clustering of viruses at species, genus, and family level was determined automatically and allocated by color strips adjacent to the phylogenomic tree (same color representing identical taxonomic unit). Red box indicates phage pAh6.2TG and its monophyletic taxa which is magnified in panel B. Trees based on (C) major capsid protein and (D) terminase large subunit were constructed by the maximum-likelihood method with 5,000 ultrafast bootstrapping. Bootstrap value (in percentage) is shown at the node, whereas scale bar indicates amino acid substitution per site. Red taxon represents the phage of this study (pAh6.2TG).
