  • a Signature genes were described as loci found in all of the genomes within the proposed group and that had a BLASTP E value of <0.1 between all members. Details about the signature genes, links to alignments, sequences, and more information can be found at http://salmonella.utmem.edu/phage/tree/signature.html.
