光敏色素光感知是细菌、蓝藻、真菌和植物中检测红光和远红光的常见机制。然而,光敏色素激活后的反应似乎是相当不同的物种之间。低等植物,如苔藓,表现出光敏色素介导的方向性反应,即向光性和向极性。这些不能用核基因调控来解释,而被认为是由细胞质或质膜上的光敏色素触发的。在高等植物中,类似的定向反应是通过向光素(一种蓝光受体)介导的,光敏色素主要通过基因调控来控制形态发生反应。然而,细胞质光敏色素反应也存在于高等植物中,这似乎与定向蓝光感知交织在一起。通过总结各自的研究结果,一个可能的保护细胞质光敏色素功能在高等和低等植物在这里解决。
Phytochrome photoperception is a common mechanism for the detection of red and far-red light in bacteria, cyanobacteria, fungi and plants. However, the responses following phytochrome activation appear to be quite diverse between species. Lower plants, such as mosses, show phytochrome-mediated directional responses, namely phototropism and polarotropism. These cannot be explained by nuclear gene regulation and are thought to be triggered by phytochromes in the cytoplasm or at the plasma membrane. In higher plants, similar directional responses are mediated via phototropin, a blue light receptor, with phytochromes mainly controlling morphogenetic responses through gene regulation. However, cytoplasmic phytochrome responses exist in higher plants too, which appear to be intertwined with directional blue light perception. By summarizing the respective findings, a possible conservation of cytoplasmic phytochrome function in higher and lower plants is addressed here.
