||Abstract: "[Investigators] present here the "Phage Proteomic Tree," which is based on the overall similarity of 105 completely sequenced phage genomes. The Phage Proteomic Tree places phage relative to both their near neighbors and all other phage included in the analysis. This method groups phage into taxa that predicts several aspects of phage biology and highlights genetic markers that can be used for monitoring phage biodiversity."
||P.4534 left column 2nd paragraph: "Using the taxa shown in Fig. 2, [investigators] identified the proteins that are conserved in every member of each group. These ORFs can be considered genetic markers for their respective groups and may be used in the future to identify the presence of uncultured representatives in the environment (Table 2). [They] call these loci signature genes. Not all groups have signature genes (e.g., lambda-like siphophages). Details and alignments of the signature genes can be found at link [as of April 11th 2016 link is broken] The website has an interactive page that allows all of the signature genes within a selection of genomes to be visualized."
