GenomeRing visualization of an alignment of three H. pylori strains (26695, J99, P12). For this view, the minimal block length was set to 50 kb. Two large-scale inversions between 26695 and J99/P12 are represented by blocks 5 and 6. Gene expression data for 26695 has been mapped into the corresponding lane (red) of all blocks. Genes upregulated in condition HU or AS are shown on the red lane, colored purple and green, respectively. The region that is shown in more detail in Fig. 5 is highlighted by a red rectangle (not part of GenomeRing visualization)
