The photosynthetic apparatus of higher plants and algae is composed of plastid- and nuclear-encoded components, therefore the expression of photosynthesis genes needs to be highly coordinated. Expression is regulated by various factors, one of the most important of which is light. Photosynthesis functions as a sensor for such light signals, and the redox state of photosynthetic electron transport components and redox-active soluble molecules act as regulating parameters. This provides a feedback response loop in which the expression of photosynthesis genes is coupled to the function of the photosynthetic process, and highlights the dual role of photosynthesis in energy fixation and the reception of environmental information.

叶绿体氧化还原信号：光合作用如何控制其自身基因。

高等植物和藻类的光合作用设备由质体和核编码的成分组成，因此需要高度协调光合作用基因的表达。表达受多种因素调节，其中最重要的因素之一是光。光合作用充当此类光信号的传感器，并且光合作用电子传输成分和氧化还原活性可溶性分子的氧化还原状态充当调节参数。这提供了一个反馈响应环，其中光合作用基因的表达与光合作用过程的功能耦合，并突出了光合作用在能量固定和环境信息接收中的双重作用。
