Circadian clocks have evolved to enhance adaptive physiology in the predictable, fluctuating environment caused by the rotation of the planet. Nutrient acquisition is central to plant growth performance and the nutrient demands of a plant change according to the time of day. Therefore, major aspects of nutrient homeostasis, including carbon assimilation and mineral uptake, are under circadian control. It is also emerging that there is feedback of nutritional status to the circadian clock to integrate these processes. This review will highlight recent insights into the role of the circadian clock in regulating plant nutrition as well as discuss the role for nutrients in affecting circadian function.
昼夜节律时钟已经进化，以在由地球自转引起的可预测、波动的环境中增强适应性生理机能。养分获取是植物生长性能的核心，并且植物的养分需求会根据一天中的时间而变化。因此，养分稳态的主要方面，包括碳同化和矿物质吸收，都受昼夜节律的控制。越来越多的研究表明，营养状况对昼夜节律时钟存在反馈，以整合这些过程。本综述将重点介绍关于昼夜节律时钟在调节植物营养方面作用的最新见解，并讨论养分在影响昼夜节律功能方面的作用。
