本文综述了趋光素和光敏色素对光运动反应的调控。蓝光受体趋光素介导各种光运动反应，如趋光性、叶绿体运动和气孔打开。在包括蕨类、苔藓和绿藻在内的隐生植物中，红光和蓝光介导向光性和叶绿体运动。红光/远红光的可逆性表明光敏色素参与了这些反应。因此，植物的生长可能是通过协调这些光运动来有效地捕获光合作用所需的光来促进的。
In this review, we describe the regulation of photomovement responses by phototropin and phytochrome photoreceptors. The blue light receptor phototropin mediates various photomovement responses such as phototropism, chloroplast movement and stomatal opening. In cryptogamic plants including ferns, mosses and green alga, red as well as blue light mediates phototropism and chloroplast movement. The red/far‐red light reversibility suggests the involvement of phytochrome in these responses. Thereby, plant growth is presumably promoted by coordinating these photomovements to capture efficiently light for photosynthesis.
