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).
