Abstract

How light signals are transduced by phytochromes is still poorly understood. Recent studies have provided evidence that a PAS domain protein, PIF3, physically interacts with phytochromes, plays a role in phytochrome signal transduction and might be a component of a novel signalling pathway in plants.

摘要

光敏色素如何转导光信号仍知之甚少。最近的研究提供了证据，表明一种含PAS结构域的蛋白质PIF3与光敏色素发生物理相互作用，在光敏色素信号转导中发挥作用，并且可能是植物中一条新信号通路的组成部分。
