Distinct chromatin signitures of promoters, enhancers and transposons in allohexaploid wheat

Bread wheat is allohexaploid with 16 Gb genome, which has large intergenic region with abundant TEs and regulatory sequences . Our results give insight into the connections between chromatin modifications and transcriptional regulatory activity and provide the first systematic epigenomic map for functional annotation of the allohexaploid wheat genome. Overall design: We integrated seven major chromatin marks, DNA methylome and open chromatin, along with transcriptomic data in allohexaploid wheat to systematically characterize distinct chromatin archetectures surrounding regulatory elements including promoters, enhancers and transposons.
