生命周期对光周期和环境温度季节变化的适应是开花植物广泛驯化背后生态成功的主要决定因素。生物钟通过产生内源节律在潜在的适应机制中发挥作用，使植物能够适应和调整 24 小时昼夜轮转和 365 天季节性公转。然而，生物钟跟踪光周期和温度季节变化的机制是该领域长期存在的课题。最近，我们开始了解光和环境温度信号如何在昼夜周期中馈入生物钟转录电路以跟踪光周期和环境温度的季节性变化的问题。我们的结果共同表明，由 LUX-ELF3-ELF4 组成的夜间复合体 (EC) 夜间阻遏蛋白在这方面发挥着至关重要的作用。在这里，我们讨论这些最近的研究以增加进一步的影响。
Life cycle adaptation to seasonal changes in photoperiod and ambient temperature is a major determinant of the ecological success behind the widespread domestication of flowering plants. The circadian clock plays a role in the underlying mechanism for adaptation through generating endogenous rhythms that allow plants to adapt and adjust to both the 24 h diurnal rotation and 365 d seasonal revolution. Nevertheless, the mechanism by which the circadian clock tracks seasonal changes in photoperiod and temperature is a longstanding subject in the field. Recently, we have begun to understand the question of how the light and ambient temperature signals feed into the circadian clock transcriptional circuitry in day-night cycles in order to track seasonal changes in photoperiod and ambient temperature. Our results collectively indicate that the evening complex (EC) nighttime repressor consisting of LUX-ELF3-ELF4 plays a crucial role in this respect. Here, we discuss about these recent studies to add further implications.
