Scheme of the dynamics of chromatin marks and TOC1 gene expression across the day. The marks for active chromatin, H3Ac and H3K4me3 (top), sequentially correlate with peaks in clock gene mRNA accumulation (bottom), whereas the mark for repressive chromatin, H3K4me2 (top), inversely correlates with TOC1 mRNA accumulation (bottom). The open bar refers to day, the dark bar refers to night.
