Plot of dinucleotide abundance profiles of E. coli and 12 Prochlorococcus strains. Differently coloured lines join the abundance values of dinucleotide pairs for each of the organisms. Abundance values ≥ 1.23 or ≤ 0.78 are significantly over or underrepresented (as described by Karlin et al., Theoretical population biology, 61, 367-390, 2002).
