Representation of sites in genomes for cases the R-M system encoded only in related genomes. Only 4–6 bp palindromic recognition sites of orthodox Type II R-M systems are considered. a Kr distributions for site-genome pairs. Blue dotted line is for pairs of the actual pairs dataset, red solid line is for pairs of the prokaryotic control dataset. Green dash-dotted line is for sites of R-M systems that are not encoded in the current genome, but are present in some strain of the same species. Orange dashed line is for sites of R-M systems that are not encoded in any genome of current species, but are present in some species of the same genus. b Percentages of site representation. Colored part of stacked column denotes underrepresented sites, grey part of stacked column is for overrepresented ones, white part of stacked column corresponds to pairs with Kr for the site between 0.78 and 1.23. Colors correspond to (a). Legend: act — actual pairs, sp — actual in another strain of the same species, gn — actual in another species of the same genus, ctr — the prokaryotic control dataset
