Dynamics of diurnal histone modifications in Arabidopsis. a Heat-map view of H3K4me3 and H3K9ac binding signals every 3 h in a 24-h period (16 h light/8 h dark). The peaks are partitioned into the morning and evening clusters. The number of peaks in each cluster is indicated at the left side of the panel. b Overlap of genes with H3K4me3 and H3K9ac peaks. c Gene Ontology (GO) analysis of the genes with diurnal H3K4me3 or H3K9ac binding peaks. d Overlap between rhythmic H3K4me3 peaks and peaks with altered H3K4me3 enrichment in the sdg2 or jmj14 mutant compared with the WT. The asterisk indicates the statistical significance level for overlap with P < 0.05. e Phase distributions of the genes with rhythmic H3K4me3 or H3K9ac peaks in the morning phase (blue line) and evening phase (black line)
