PHYTOCHROME INTERACTING FACTORS mediate metabolic control of the circadian system in Arabidopsis.

ABSTRACT: The circadian (c. 24 h) system has a central role in regulating the timing and coordination of photosynthesis, and in turn photosynthesis and photosynthetic products which are controlled by the circadian clock feedback to affect the circadian oscillator that generates rhythms. However, little is known about the mechanism(s) by which this feedback occurs. One group of likely candidates for signal transduction to the circadian clock are the PHYTOCHROME INTERACTING FACTOR (PIF) family of transcription factors which have been shown to be involved in numerous signaling pathways in Arabidopsis. Yet despite evidence that some PIF genes are under circadian control and bind promoter motifs present in circadian genes, until now PIFs have not been shown to affect the circadian system.
