昼夜节律振荡器是一个相互连接的反馈回路的复杂网络，它调节着广泛的生理过程。事实上，生物钟基因的变异与一系列植物环境适应有关，包括生长调节、开花的光周期控制以及对非生物和生物胁迫的反应。虽然生物钟会受到环境的影响，在各种条件下保持大约24小时的节律，但它也可以通过环境线索（如光线或温度的急剧变化）进行重置。这些相互竞争的需求可能有助于解释生物钟网络和环境反应途径之间联系的复杂性。在这里，我们讨论了我们目前对时钟的理解及其与光和温度信号通路的相互作用。我们还描述了不同的时钟基因等位基因，已牵连在重要的主食作物的驯化。
The circadian oscillator is a complex network of interconnected feedback loops that regulates a wide range of physiological processes. Indeed, variation in clock genes has been implicated in an array of plant environmental adaptations, including growth regulation, photoperiodic control of flowering, and responses to abiotic and biotic stress. Although the clock is buffered against the environment, maintaining roughly 24-h rhythms across a wide range of conditions, it can also be reset by environmental cues such as acute changes in light or temperature. These competing demands may help explain the complexity of the links between the circadian clock network and environmental response pathways. Here, we discuss our current understanding of the clock and its interactions with light and temperature-signaling pathways. We also describe different clock gene alleles that have been implicated in the domestication of important staple crops.
