Circadian clock regulates dynamic chromatin modifications associated with Arabidopsis CCA1/LHY and TOC1 transcriptional rhythms.

Plant & cell physiology - 1 Dec 2012

Hemmes Hans, Henriques Rossana, Jang In-Cheol, Kim Sanghee, Chua Nam-Hai

Abstract excerpt

Circadian clocks enable organisms to adapt to a 24 h diurnal cycle and anticipate rhythmic changes in the environment. The Arabidopsis central oscillator contains three genes encoding core clock components. CIRCADIAN CLOCK ASSOCIATED 1 (CCA1)/LATE ELONGATED HYPOCOTYL (LHY) and TIMING OF CAB EXPRESSION 1 (TOC1) reciprocally repress genes encoding each other and are critical for the generation of circadian rhythms...
