Figure 1.

Conservation of gene order in prokaryotic genomes in relation to phylogenetic distance, measured as the number of substitutions in SSU rRNA. Each point represents a pair of species. (a) Results for all species. (b) Same plot as in (a), but with Archaea removed and values for some bacterial species highlighted.
