The plant circadian clock coordinates developmental, physiological, and metabolic processes with diel changes in light and temperature throughout the year. The balance between the persistence and plasticity of the clock in response to predictable and unpredictable environmental changes may be key to the clock's adaptive nature across temporal and spatial scales. Studies under controlled conditions have uncovered critical signaling pathways involved in light and temperature perception by the clock; however, they don't account for the natural lag of temperature behind photoperiod. Studies in natural environments provide key insights into the clock's adaptive advantage under more complex natural settings. Here, we discuss the role of the circadian clock in light and temperature perception and signaling, how the clock integrates these signals for a coordinated and adaptive response, and the adaptive advantage conferred by the clock across time and space in natural environments.

植物生物钟在自然环境中的适应性。

植物生物钟协调发育、生理和代谢过程，以及全年光照和温度的变化。时钟响应可预测和不可预测的环境变化的持久性和可塑性之间的平衡可能是时钟在时间和空间尺度上的适应性的关键。在受控条件下的研究揭示了时钟感知光和温度的关键信号通路；但是，它们没有考虑到光周期之后温度的自然滞后。对自然环境的研究为时钟在更复杂的自然环境下的适应性优势提供了关键见解。在这里，我们讨论生物钟在光和温度感知和信号传导中的作用，
