Distinct feature of different ACRs in transcriptional regulation in wheat. a Subdividing ACRs based on distribution pattern around genes, and correlation between /gACRs and genes expression. b Heatmap showing stage-specific pACRs and corresponding genes expression pattern. c Distinct gain and loss of pACRs and dACRs between adjacent embryonic developmental stages. d Venn diagram showing overlapping dACRs among DPA6, 8, and 12. e Histone modifications enrichment at transient dACRs. Overlap between transient dACRs peaks and different epigenetics modification peaks was calculated by bedtools and peaks with 1 bp overlap were considered as overlap. The observed/expected ratio was calculated between the observed overlap number divided randomly selected background overlap number. The randomly selected background was generated from genomic intervals that with any epigenetics modification and located in intergenic regions. For more details, see Method. f The number of expressed non-coding RNA during DPA6-12. g IGV showing the transient dACRs was correlated with non-coding RNA-specific expression at DPA8, which overlapped with TEs. h Comparisons of chromatin accessibility of collinear regions among subgenomes, chromosome 2B compared to 2A (up-left) and chromosome 2D with 2A (down-left). Collinear regions were identified based on sequence conservation (right). Color bars on x and y axis indicate the chromosome segments defined by IWGSC Refseq v1.0. Grey lines indicate the centromere for individual chromosomes. Mann–Whitney U test (two-sided) was used for a. Fisher exact test was used for e and f. *p <  = 0.05; **p <  = 0.01; ***p <  = 0.001; ****p <  = 0.0001
