Figure 4.

Genome maps for phage ΦCP9O, ΦCP13O, ΦCP26F, and ΦCP34O. Arrows are shown in presumed direction of transcription. Grey arrows indicate genes of unknown homology or function, colored arrows indicate genes belonging to pfam families or clusters of orthologous groups (COGs) as classified by IMG. Functional categorizations of pfam designations are shown in the legend. For predicted ORFs with unknown function, sequence similarity clustering at a 40% similarity cutoff is indicated by shading.
