Figure 1.

Relationship between percentage of genes belonging to paralogous families plotted versus genome size in 127 eubacterial genomes. Inset shows the average gene family size versus genome size for the same genomes, except Shigella flexneri, Bordetella pertusis, B. parapertussis and B. bronchiseptica, which contain a high number of IS elements. Some genomes with atypical values are identified: Mpn, Mycoplasma pneumoniae; Mpt, Mycoplasma penetrans; Mga, Mycoplasma gallisepticum; Mlp, Mycobacterium leprae; Pir, Pirellula sp.
