Extended Data Fig. 4: Construction of TRN of wheat regeneration.

a, Pipeline for TRN construction. b, Location distribution of footprint within the peak of ATAC-seq (data from DAI 6 stage). c, Distribution of the width of TF footprint (data from DAI 6 stage). d, Numbers of footprint at different stages. e, Sequence conservation analysis at footprint sites; The background is randomly selected intergenic regions outside the open chromatin and coding regions; All regions are truncated to 25 bp. f, Protection scores dynamic of differential footprint; Protection score reflects the chromatin accessibility of footprint. g, Overview of the TRN of wheat regeneration. h, Two transcriptional regulatory modes during wheat regeneration. i, A network of functional related TFs in regulatory mode Type I. j, A network of functional related TFs in regulatory mode Type II.
