所有的植物生产力，包括我们所吃的食物，都来自于植物对太阳能的捕捉。在大多数纬度地区，由于行星的自转，一天中只有24小时的一部分时间可以获得阳光。这种有节奏的和可预测的环境变化推动了生物钟的进化，生物钟对植物分子生物学、生理学和物候学产生了极其普遍的影响。最近的一些研究表明，生物钟与光合作用及其代谢产物密切相关。我们考虑了昼夜节律振荡器与碳水化合物生物化学的耦合，以及核编码的昼夜节律时钟与叶绿体内的过程之间的联系。我们描述了这可能如何提供适应，以优化植物在环境中的表现，这种环境在每天和季节的基础上都是可预测的，并且由于天气的原因而不可预测地变化。
All plant productivity, including the food that we eat, arises from the capture of solar energy by plants. At most latitudes sunlight is available for only part of the 24 h day due to the rotation of the planet. This rhythmic and predictable alteration in the environment has driven the evolution of the circadian clock, which has an extremely pervasive influence upon plant molecular biology, physiology and phenology. A number of recent studies have demonstrated that the circadian clock is integrated very closely with photosynthesis and its metabolic products. We consider the coupling of the circadian oscillator with carbohydrate biochemistry and the connections between the nuclear-encoded circadian clock and processes within chloroplasts. We describe how this might provide adaptations to optimize plant performance in an environment that varies both predictably upon a daily and seasonal basis, and unpredictably due to the weather.
