Abstract
Two or more kinetically distinguishable populations of phytochrome molecules were observed in living tissues of oat, pea, maize, and cauliflower, as well as in extracts of oat. At least 3 different populations occurred in cauliflower florets, while 2 were observed in each of the other species. In extracted oat phytochrome, the relative proportions of the 2 forms remained constant during successive stages of purification. The physiological significance of this multiplicity of forms remains unclear.
摘要
在燕麦、豌豆、玉米和花椰菜的活体组织以及燕麦提取物中，观察到两种或更多种运动状态不同的光敏色素分子。在花椰菜花朵中至少存在 3 种不同的群体，而在其他两种植物中则观察到 2 种。在提取的燕麦光敏色素中，两种形式的相对比例在连续的纯化阶段保持不变。这种多种形式的生理意义尚不清楚。
