| we also found that CCA1 is required for both a short- and long-term response of the circadian oscillator to sucrose, while LHY acts to attenuate the effects of sucrose on circadian period. Together, this work highlights new pathways for how sucrose could be signaling to the oscillator and reveals further functional separation of CCA1 and LHY. | Physiological and Genetic Dissection of Sucrose Inputs to the Arabidopsis thaliana Circadian System.
