STRUCTURE & EVOLUTION OF PLANT PHOTORECEPTOR PHYTOCHROME

适应外部光环境变化的能力 对植物的生存尤为重要，因为与动物不同， 植物依靠阳光进行光合作用， 神经肌肉系统，使他们能够移动到一个更合适的光 环境 因此，植物具有独特的感光能力， 感光分子光敏色素，使它们能够感知 的强度，方向和光谱质量的频繁波动， 光在环境中。 除了光合作用 光敏色素存在于所有光合自养生物中， 从绿色藻类到高等植物。 我们的研究寻求提供新的见解 光敏色素受体的结构和进化 通过比较分析植物光敏色素基因， 代表性的高等和低等植物物种。

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.
