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.

摘要

拟南芥的早花3（ELF3）基因调控植物形态、开花时间和昼夜节律。ELF3被认为是光敏色素及可能其他光感受器下游光信号转导的调节因子。最近的研究表明，ELF3编码一种新型核蛋白，该蛋白有节律地表达并与光敏色素B相互作用。ELF3如何介导光反应的昼夜节律门控以及如何调节生物钟的光输入是讨论的主题。
