蓝藻是已知表现昼夜节律的最简单的生物，并为在分子、生理和生态水平上解剖昼夜节律组织的基本特性提供了实验模型系统。本文综述了蓝藻生物昼夜节律产生的分子和遗传机制。最近的分析揭示了原核生物昼夜节律系统中存在多种反馈过程，并导致了一种新的分子振荡器模型。在这里，作者总结了目前对蓝藻振荡器的理解和开放的问题。
Cyanobacteria are the simplest organisms known to exhibit circadian rhythms and have provided experimental model systems for the dissection of basic properties of circadian organization at the molecular, physiological, and ecological levels. This review focuses on the molecular and genetic mechanisms of circadian rhythm generation in cyanobacteria. Recent analyses have revealed the existence of multiple feedback processes in the prokaryotic circadian system and have led to a novel molecular oscillator model. Here, the authors summarize current understanding of, and open questions about, the cyanobacterial oscillator.
