title: ELF3: a circadian safeguard to buffer effects of light.
abstract: The EARLY FLOWERING 3 (ELF3) gene of Arabidopsis regulates plant morphology, flowering time and circadian rhythms. ELF3 was proposed to function as a modulator of light signal transduction downstream of phytochromes, and, perhaps, other photoreceptors. Recent work indicates that ELF3 encodes a novel nuclear protein that is expressed rhythmically and interacts with phytochrome B. How ELF3 mediates the circadian gating of light responses and regulates light input to the clock is the subject of discussion.
