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.

适应外部光照环境变化的能力 对于种植生存特别重要，因为与动物不同 植物依靠光合作用的阳光，它们没有 神经肌肉系统，使它们能够移动到最佳的光线 环境。 因此，植物具有独特的光感应 感光细胞分子植物色素，使它们能够感知 强度，方向和光谱质量的频繁波动 在他们的环境中点亮。 除光合作用外 细菌，植物色素均在所有光生生物中都发现 绿藻到上等植物。 我们的研究试图提供新的见解 进入植物色素光感受器的结构和演变 通过对植物色素基因的比较分析 代表性更高和较低的植物物种。
