Comparative epigenomic landscapes and transcriptional regulatory features in diploid progenitors and allotetraploid Brassica napus. A. Phototypes of Brassica rapa, B. oleracea, and B. napus plants and data generation in this study. Two-week-old plants were shown. Bar, 2 cm. B. Number of peaks for 4 histone modifications and accessible chromatin regions (ACRs). C. B. rapa, D. B. oleracea, and E. B. napus: Distribution of all epigenomic feature signals near gene regions (±2 kb). Genes were categorized by expression levels. Representative IGV browser examples display a highly expressed gene (left) and a lowly expressed gene (right), along with associated histone modifications and nearby regions of chromatin accessibility.
