The ability to adjust to changes in the external light environment is especially important to plant survival because, unlike animals, plants depend on sunlight for photosynthesis and they do not have a neuromuscular system which allows them to move to a more optimum light environment. Plants therefore possess the unique light-sensing photoreceptor molecule phytochrome which enables them to perceive the frequent fluctuations of intensity, direction and spectral quality of light in their environment. With the exception of photosynthetic bacteria, phytochrome is found in all photoautrophic organisms from green algae to higher plants. Our studies seek to provide new insight into the structure and evolution of the phytochrome photoreceptor through comparative analysis of the phytochrome genes from representative higher and lower plant species.

适应外部光环境变化的能力 对于植物的生存尤其重要，因为与动物不同， 植物依靠阳光进行光合作用，它们没有光 神经肌肉系统使它们能够移动到更佳的光线下 环境。 因此植物具有独特的光感应能力 光感受器分子光敏色素，使它们能够感知 强度、方向和光谱质量的频繁波动 他们的环境中的光。 除了光合作用之外 细菌，光敏色素存在于所有光自营养生物中 绿藻到高等植物。 我们的研究旨在提供新的见解 光敏色素感光体的结构和进化 通过对光敏色素基因的比较分析 代表高等植物和低等植物种类。
