Synteny variation between phages and prophages in VCs. (a) VC_F14 (lytic phages only); (b) VC_F62 (nine predicted temperate phages and two prophages); (c) VC_P3 (prophages only); and (d) percentage of shared PCs among pairs of phage genomes in the 51 VCs, with VCs comprising lytic phages only, composite, and prophages only, shown in different colours. Functional annotation is shown in the colour key, and the percentage of similarity between ORFs is shown in greyscale.
