一系列新的研究揭示了被称为光敏色素的红色/远红色光感受器是如何起作用的。光敏色素A和光敏色素B在被光激活时各自移动到细胞核，光敏色素A是一种激酶。光敏色素相互作用蛋白提供了候选的信号转导成分，最近的一项生理研究表明，phyA可能介导对远红光的反应。光敏色素核定位和激酶活性的调控产生了多种光敏色素，每种光敏色素可能具有不同的调控活性。
A series of new studies reveal how the red/far-red light photoreceptors called phytochromes act. Phytochrome A and phytochrome B each move to the nucleus when activated by light, and phytochrome A is a kinase. Phytochrome-interacting proteins provide candidate signal transduction components and a recent physiological study suggests how phyA may mediate responses to far-red light. Regulation of phytochrome nuclear localization and kinase activities creates multiple phytochrome species, which may each have different regulatory activities.
