Enrichment of CArG-box variants in peak centers. A peak center is defined as the 250 bp upstream and downstream of the peak summit. a Frequency of peak centers containing different CArG-box variants divided by the frequency in random 500 bp stretches in the Arabidopsis thaliana genome. Black, relative frequency of CArG-box variant in all Arabidopsis promoters. b Kernel density plot of positions of different CArG-box variants in peak centers of SEP3 relative to peak summits
