Figure 3

Absence of DNA curvature-related periodicity at prophage integration sites. The top panel shows a periodicity scan of the Mycoplasma hyopneumoniae J chromosome and the bottom panel shows a periodicity scan of a section of the Campylobacter curvus 525.92 chromosome containing a prophage. The intensity of the periodic signal for a given chromosomal location shown on the horizontal axis and the period shown on the vertical axis is signified by the level of grey. White regions correspond to a weak periodic signal while black indicates a strong periodicity (See Methods for details). A 10 kb window was moved in steps of 5 kb. Locations of prophages predicted by the Prophinder are marked by the bars above the plot. M. hyopneumoniae has a predicted prophage at positions 469,140–481,698 bp and C. curvus at 1,857,093–1,873,803 bp.
