Figure 2

Persistency of the periodic signal in chromosomes with and without prophages. Top left: The MaxMax value (a measure of persistency of a dominant sequence periodicity in a chromosome) is plotted for each chromosome with at least one prophage against the G + C content (blue diamonds). Analogous data for randomized sequences preserving the overall G + C content and size of the original sequence are shown for comparison (red circles). Bottom left: A similar plot but showing the MaxMax values as a function of the chromosome size. Top right and bottom right: the same plots for chromosomes with no prophages. The classification of chromosomes with and without prophages relies on Prophinder predictions.
