Effect of priming on H3K27me3 island length distribution. (A) Island length histograms plotting absolute number of H3K27m3 islands against island length in 200 bp length windows. (B) Island length histograms plotting percentage of H3K27m3 islands (relative to total island number in the sample) against island length in 200 bp windows. (C) Island length histograms for H3K4m2 and H3K4m3. (D) Island length histograms for H3K9m2. In all histograms values for non-primed root samples (CR) are given in dark colors, values for primed root samples (PR) are given in light colors.
