(a) The neighbor-joining tree (with 500 bootstrap value) constructed based on the amino acid sequence of the protein of large terminase subunit 590B ( red triangle) and related phages using MEGA-X. (b) and (c) are circular and rectangular phylogenetic trees generated using ViPTree. Phage 590B (highlighted with a red star) and all sequenced genomes of phages from Virus–host DB (RefSeq release 212) were included in the analysis [27]. The outer and inner rings are colored according to the host group and virus family, respectively.
