Gene organization of the Gifsy-2 bacteriophage. Data were from reference and our laboratories. (Top) Open reading frames with identifiable orthologs in phage lambda are labeled. Most of these genes are termed gft (Gifsy-2), e.g., gftO. White arrows, putative virulence genes; gray arrows, putative phage genes; lines, deletion intervals. (Bottom) Gene organization of the B region. Genes with no obvious role in phage production are termed gtg (Gifsy-2 gene) ().
