Plot of genome size versus the number of coding sequences (CDS) for completed bacterial genomes. This figure includes complete Bacterial and Archaea genomes as listed in the Genomes online database as of May 1, 2003(http://wit.integratedgenomics.com/GOLD/). Prokaryotic genomes that have relatively low gene number/genome size ratio include Bacteroides thetaiotaomicron, two members of Archaea (Methanosarcina acetivorans and Methanosarcina mazai), two Xanthomonas species, and Mycobacterium leprae.
