Abstract

Red and far-red light-sensing phytochromes are widespread in nature, occurring in plants, algae, fungi, and prokaryotes. Despite at least a billion years of evolution, their photosensory modules remain structurally and functionally similar. Conversely, nature has found remarkably different ways of transmitting light signals from the photosensor to diverse physiological responses. We summarize key features of phytochrome structure and function and discuss how these are correlated, from how the bilin environment affects the chromophore to how light induces cellular signals. Recent advances in the structural characterization of bacterial and plant phytochromes have resulted in paradigm changes in phytochrome research that we discuss in the context of present-day knowledge. Finally, we highlight questions that remain to be answered and suggest some of the benefits of understanding phytochrome structure and function.

植物色素的新发现:连接结构与功能
红光和远红光感光植物色素广泛存在于植物、藻类、真菌和原核生物中。尽管经历了至少十亿年的进化,它们的光感模块在结构上和功能上仍然相似。相反,自然界却找到了截然不同的方法,将光信号从光敏元件传递到各种生理反应。我们总结了植物色素结构和功能的关键特征,并讨论了这些特征之间的相互关系,包括比林环境如何影响发色团以及光如何诱导细胞信号。细菌和植物植物色素结构表征方面的最新进展导致了植物色素研究范式的改变,我们将结合当今的知识对其进行讨论。最后,我们强调了仍有待回答的问题,并提出了了解植物色素结构和功能的一些益处。
