Genome signature phylogenetic classification of known bacteriophages using a viral database. Each bacteriophage fragment was subjected to genome signature classification as described in Materials and Methods. Each fragment was classified according to its position on the genome signature phylogeny, and each position compared with that of its classification based on morphological features. The percentage of bacteriophage fragments classified consistent with that of its morphological features is represented. Blue represents full length bacteriophages, red represents random bacteriophage fragments of 10,000 nucleotides, yellow represents random bacteriophage fragments of 5,000 nucleotides, and cyan represents random bacteriophage fragments of 2,000 nucleotides. Error bars represent standard error from a compilation of 5 separate experiments.
