The plant circadian system mostly includes input pathways, a core oscillator and output pathways to sense and anticipate the timing cues of the environment to optimize plant growth and fitness. As the cellular core coordinating system, the plant circadian system can sense the daily recurring light and temperature dynamics to coordinate the metabolism and multiple physiology processes, providing an adaptive advantage for plant growth and development. The core circadian oscillator regulates multiple complex downstream networks at various levels. Here, we summarize recent major research progress in deciphering the underlying mechanisms of the core oscillator and its regulatory networks. We also highlight a few fundamental questions needing to be resolved.
