Enrichment analysis of histone modifications within DMVs and DMV genes. A Mean enrichment levels of histone modifications around genes (from 2 kb upstream to 2 kb downstream of the gene body). Maximum enrichment level was normalized to 1 for each histone mark. TSS and TTS indicate the transcription start site and transcription termination site, respectively. B Average enrichment of histone modifications over DMVs including the flanking 1-kb regions (red lines). The DMV region is indicated by the gray area. Randomized genome regions were used as control regions and shown as gray lines. C Proportion of all genes and DMV genes marked by different histone modifications. D Mean enrichment levels of different histone modifications around expressed (left panel) and non-expressed DMV genes (right panel) in the endosperm. E Average enrichment depth of histone modifications around constitutively expressed genes (up) and seed-specific genes within DMVs (down) in leaves (red lines) and endosperm (cyan lines)
