植物生物钟参与许多过程的调节。它充当计时器，确保关键发育事件的发生与适当的条件一致。尽管内部振荡时钟机制可能是为了响应地球可预测的昼夜周期而进化的，但生物体必须整合一系列外部和内部线索来调整发育和生理机能。这里我们引入三种不同的时钟输出来说明时钟控制的复杂性。生物钟调节的昼夜生长会因环境刺激而改变。光周期开花途径的复杂性突出了许多节点，植物可以通过这些节点整合信息来调节物候输出的时间。对开花反应不同的生态型之间的比较分析揭示了影响开花的额外环境因素和分子过程。我们还探索了冷适应过程，其中昼夜节律输入、光质量和应激反应汇聚在一起，以提高对寒冷温度的耐受性。
The plant circadian clock is involved in the regulation of numerous processes. It serves as a timekeeper to ensure that the onset of key developmental events coincides with the appropriate conditions. Although internal oscillating clock mechanisms likely evolved in response to the earth’s predictable day and night cycles, organisms must integrate a range of external and internal cues to adjust development and physiology. Here we introduce three different clock outputs to illustrate the complexity of clock control. Clock-regulated diurnal growth is altered by environmental stimuli. The complexity of the photoperiodic flowering pathway highlights numerous nodes through which plants may integrate information to modulate the timing of phenological outputs. Comparative analyses among ecotypes that differ in flowering response reveal additional environmental cues and molecular processes that have developed to influence flowering. We also explore the process of cold acclimation, where circadian inputs, light quality, and stress responses converge to improve freezing tolerance in anticipation of colder temperatures.
