Figure 3

Compositional discordance between plasmids and their host's according to the plasmid size. The proportion of genomic fragments of the representative host chromosome with a δ* value lower than that of the plasmid is plotted as a function of plasmid size. Note the logarithmic scale on the X axis. Thirty-five plasmids have a δ* value lower than that of 80% (values range from 29% to 80%) of the identical sized fragments of their host's genome (red symbols), while 42 plasmids have a δ* value higher than all identical sized fragments of their host's genome (yellow symbols).
