Analysis of fully sequenced Bacillus phage genomes belonging to clusters A through G reveals 12 subclusters. Subcluster divisions are provided by blue lines and are indicated on the Y-axis when there are more than one per cluster. Individual phages are separated by red lines. Phage names are provided on the X-axis and Y-axis with host abbreviation from which the phages were isolated indicated on the Y-axis. The founding phage for each cluster is bolded. Hosts abbreviations are Bacillus anthracis (A), Bacillus cereus (C), Bacillus sp. (B), Bacillus megaterium (M), Bacillus pumilus (P), Bacillus subtilis (S), Bacillus thuringiensis (T), and Bacillus weihenstephanensis MG1, (W). Dot plots were produced using Gepard . Phage Andromeda is abbreviated (Andro.).
