Fig. 1: A multi-tissue map of accessible chromatins in maize.

a Overview of the 12 major maize tissues we profiled in this study. Except for the ear and seedling, which had two and three ATAC-seq data, the other tissues had a single ATAC-seq data. We hereafter used sample to represent each of the 15 ATAC-seq data. b The number and length of ACRs identified in each sample (seedling1, seedling2 and seedling3 represent three different seedling samples). c Circos plot showing the chromosomal distribution of ACRs in each sample. Tracks from outer to the inner represented chromosome ideograms, retrotransposons, DNA transposons, gene density and ACR density of 15 samples, respectively. d The distribution of ACRs on different genomic features (genic, proximal and distal). e Bar plot showing the composition of different TE superfamilies in ACRs and random control regions. f The ranking of enriched motifs in ear (2 ~ 4 mm), root, and mesophyll. Different TF families are indicated by colored dots. The P-value of each motif was estimated using one-sided Fisher’s exact test. g Upset plot showing the ACRs that conserved or specifically existed across 15 samples. A plot of saturation analysis by fitting the Michaelis-Menten equation was attached and the error bars represent the average value ± standard deviation (SD).
