Genomic map of P. fluorescens phage ϕIBB-PF7A and P. putida phage gh-1. Filled green boxes are hypothetical proteins unique of ϕIBB-PF7A, red filled boxes with black and blue outlines indicate genes of ϕIBB-PF7A which show homology to conserved essential genes of and to nonessential conserved genes of gh-1, blue filled boxes are genes present only in phage gh-1. Putative transcription promoters are indicated by lines with arrowhead: black - early host RNA polymerase promoters; dark grey - phage RNA promoters. Lines with filled black spheres indicate ρ-independent terminators. Unfilled dark grey outlined boxes indicate direct terminal repeats and dark lines at left and right indicate the ends of the genome.
