Genomic comparison at the nucleotide level of S144 genome to the other two phages in the Loughboroughvirus genus and five representatives from the closest genus, the Rosemountvirus genus. (a) Whole-genome pairwise comparison of the eight phage nucleotide sequences, visualized as a matrix with percent identity with CLC Main Workbench 7. (b) Organization and functional modules of the eight phage genomes. This figure was generated using EasyFig. Genes for phage morphogenesis are marked in blue (light blue: capsid, cyan: tail, blue: baseplate), genes for DNA packaging in green, putative genes for lysis in pink, genes involved in DNA manipulation in red, putative genes for nucleotide biosynthesis in purple and additional functions in ochre (prot. = protein). Blue shade indicates the level of similarity.
