Abstract

Plants see light through multiple photoreceptors, including phytochromes and cryptochromes. Cryptochromes are flavoproteins that participate in many blue-light responses, including phototropism in plants and entrainment of circadian rhythms in plants and animals. A novel flavoprotein, NPH1, is also implicated in plant phototropism. Phytochromes function as serine/threonine kinases whose potential interacting partners include cryptochrome (CRY1 and CRY2).

摘要

植物通过多种光感受器感知光线，包括光敏色素和隐花色素。隐花色素是黄素蛋白，参与许多蓝光反应，包括植物的向光性以及植物和动物昼夜节律的调节。一种新的黄素蛋白NPH1也与植物的向光性有关。光敏色素作为丝氨酸/苏氨酸激酶发挥作用，其潜在的相互作用伙伴包括隐花色素（CRY1和CRY2）。
