Genome and chromosome distribution of H3K4me3 in all the wheat lines used in this study. From the outside to the inside, the lines are DD diploid “TQ18,” tetraploid wheats “TD265” (wild), “TTR13” (domesticated), and “ETW” (extracted from hexaploid wheat), hexaploid wheats “XX329” (resynthesized) and “TAA10” (donor to ETW). Different colors represent different lines, each with two biological replicates. The outermost layer is the position information of chromosomes, in which pale yellow denotes the centromeric and pericentromeric region (Proximal (C)), light blue represents the chromosome arm (Interstitial (R2a/R2b)), and dark blue indicates the end of the chromosome (Distal (R1/R3)). The punctuated innermost red lines represent length of all the seven wheat chromosomes [28]
