Specific enriched DNA motif associated with ovules and fiber elongation. A Percentage of overlap between differentially expressed genes (DEGs) and genes linked to differentially opened chromatin regions (DOCRs). B Schematic representation of the functional relationship between DOCRs at ovule and fiber elongation. C–F Left: overview of DNase-seq and RNA-seq tracks for representative ovule activating DOCRs (C), ovule repressing DOCRs (D), elongation activating DOCRs (E), and elongation repressing DOCRs (F). The dotted box represents the DOCRs. Middle: representative TF motifs enriched in activating and repressing DOCRs in the ovule and elongation domains. Right: GO terms enrichment analysis of each DOCR-related gene group was indicated. The x-axis represents the values of − log10(p-value)
