Genomic composition and distribution of features. a Definition of genomic regions. Promoters are defined from 1Â kb upstream to 200Â bp downstream from the TSSs, flanking regions are 4Â kb upstream from the promoters and 5Â kb downstream from the TTSs. TE transposable elements, distal intergenic regions that are more than 5Â kb away from genic regions and are not TEs. b Composition of the entire maize genome according to AGPv4 and (c) the uniquely mappable genome. Distribution of (d, f) DHSs, (h, j) H3K9ac, (l) LUMRs and (n, o) enhancer candidates over the different genomic regions, and (e, g, i, k, m) the fractions (Mbp/Mbp, from 0 to 1, y-axes) the different features (x-axes) occupy at the various genomic regions in the uniquely mappable genome. The grey bars indicate the fraction of overall occupancy in the uniquely mappable genome.
