Fig 4. Genome analyses of sequenced phages SEN1, SEN4/5, SEN22, and SEN34.

Genome comparison of phages isolated from subsp. salamae (A) and from subsp. diarizonae (B). Schematic organization of genes in phage genomes (head-tail-regulation-replication) is shown with bold black lines. The most variable genes (i.e., those encoding DNA transfer proteins and tail fibers) are shown in blue. Genes for integration (int) are violet, genes encoding lysis are black, the locus responsible for O antigen modification (gtr) is yellow, the locus for lysogenic conversion (cor) is grey, and the locus for recombination (rec) is white. Mobile elements (transposons, HNH endonucleases) are green and the remaining genes are orange. Comparisons of phage genomes were prepared using Easyfig software [25]; similarity between phages (> 65%) is shown using a gray scale (bottom left).
