Figure 1.
Depiction of overlapping genome size in members of the Bacteria (blue), Archaea (red), Eukarya (green), and viruses (yellow), in the size range (∼0.5-10.5 Mb) in which this overlap has been found to occur. Number of circles at a given point on the scale indicates the number of completed genomes of a specific size. Circles representing unusually small (<1 Mb) or large (>5.5 Mb) bacterial genomes are labeled with the species name. Reprinted with permission from Elsevier © 2005, from Ward and Fraser 2005.
