Distribution of DHSs under extended darkness and control condition. (a) Percentage of DHSs within different regions of the Arabidopsis genome under extended darkness and control conditions. The genome was divided into six classes: promoter, 5′UTR, 3′UTR, coding exon, intron and intergenic regions. The “Genome” panel represents the proportion of these six classes in Arabidopsis genome. (b,c) The profile of the DHS distribution in all Arabidopsis non-TE (b) and TE (c) genes including 1 kb upstream and downstream under both extended darkness and control conditions. A meta-gene profile was generated using the normalized sequencing density of DHSs. The X-axis represents the conversion of the gene body into a percentage to standardize genes of different lengths. The 1-kb upstream and downstream regions of the gene are included. The Y-axis represents average values of DNase hypersensitivities. (d) Number of non-TE and TE genes associated with DHSs under darkness and light. (e) Number of DHS-changed non-TE and TE genes under darkness and light.
