Epigenomic organisation and CO frequency in the <i>A. thaliana</i> genome.

<p>(A) Physical maps of <i>A. thaliana</i> chromosomes showing genes/Mb (olive green), repeats/Mb (black), cM/Mb (red), H3K3me3/Mb (light green), LND/Mb (dark green) and DNA methylation density (blue). Dotted horizontal lines indicate the means weighted by intermarker distance. Vertical magenta lines indicate the centromeres. Grey shaded areas indicate the pericentromeres. (B) Pairwise correlations between cM/Mb, genes/Mb, H3K4me3/Mb, LND/Mb and DNA methylation in either chromosome arms or pericentromeres. Pearson's correlation coefficients (r) and associated p-values (p) are shown and regression lines are plotted in red.
