Figure 4: Phylogenetic tree based on large terminase subunits of selected bacteriophages.
From: Characterization of a novel Achromobacter xylosoxidans specific siphoviruse: phiAxp-1

The large terminase subunits were compared using the ClustalW program, and the phylogenetic tree was generated using the neighbour-joining method and 1000 bootstrap replicates.
