Involvement of chromatin accessibility in pericentromeric regions in the ovule and fiber stages. A Grouping of genes by the pattern of DHSs in promoter and closest gene expression. All expressed gene were categorized into 13 clusters (I to XIII). The numbers in brackets represent the number of genes in each cluster. Gene expression values and level of chromatin accessibility in the promoter, normalized to 0–1 with the 95th quantile value of each column, are indicated with a white to red graded color. B Relative transcript level and promoter DHSs changes for cluster VII and VIII genes. C Distribution pattern of all genes, cluster VII and cluster VIII genes on the genome. Cluster VII gene is significantly enriched in TE-rich region and cluster VIII gene is significantly enriched in gene-rich region. D Gene Ontology (GO) terms with significant enrichment levels were present for clusters VII and VIII
