Figure 2From: Stretches of alternating pyrimidine/purines and purines are respectively linked with pathogenicity and growth temperature in prokaryotesThe box-plot shows the distribution of genomic purine stretches consisting of 10 bp or more in prokaryotic phyla. The expected genomic fraction of RR-stretches is 0.001 (0.1%). The Actinobacterial and β-Proteobacterial groups were the only ones found to be underrepresented in terms of genomic RR-stretches.Back to article page
