Prophages are underlined. The strongly positionally conserved genes are depicted with circles. The inclined gene symbols (e.g. prt) depict genes that are conserved in terms of position and existence among most, but not all, of the phage members.<p><b>Copyright information:</b></p><p>Taken from "Genome classification by gene distribution: An overlapping subspace clustering approach"</p><p>http://www.biomedcentral.com/1471-2148/8/116</p><p>BMC Evolutionary Biology 2008;8():116-116.</p><p>Published online 23 Apr 2008</p><p>PMCID:PMC2383906.</p><p></p
