Figure 2.

Breakdown of complete genomes of members of the order Caudovirales (dsDNA viruses, no RNA stage) available from NCBI Genome on November 21, 2016 (n = 1943). The number of publicly available Caudovirales genomes had only increased to 2044 by July 6, 2017. Genera of prokaryotes (with some families and higher taxa) infected by phages are shown around the chart; colours correspond to phyla (kingdom in the case of the Archaea) of prokaryotes infected by different phages. Aggregated data are shown for each of the three families of the order Caudovirales in the large plot. Myoviridae, n = 538 complete genomes; Siphoviridae, n = 1063 complete genomes; Podoviridae, n = 342 complete genomes.
