Pangenome map of the phages examined. The map represents the core genome of the phages analyzed here. The core genome is the collection of conserved ORFs represented by color arrows and numbered 1 to 47 below the map. Color code for arrows denotes: red, assigned function; green, unknown function, and purple, virion structural proteins identified by mass spectrometry in PaMx73 particles. The regions of genomic plasticity, RGPs A to I above the map (not to scale), indicate the location of the accessory genes in the pangenome. The individual accessory ORFs for each genome are indicated in low case font a to i below the corresponding RGPs. Anti-CRISPR-related genes [50, 51] detected by sequence homology are encircled in orange. Notice that accessory ORF g9 is associated with all known anti-CRISPR genes [50, 51]. Functions assigned by sequence homology to known phage proteins are indicated above the map. The functional modules in the pangenome are indicated by brackets on top of the figure.
