Intrinsic period stability of the cyanobacterial circadian oscillator across in vitro and in vivo conditions

Proceedings of the National Academy of Sciences, Volume 123, Issue 12, March 2026. <br/>SignificanceThe circadian clock exhibits remarkable precision and environmental insensitivity of its period, enabling organisms to anticipate daily environmental changes. In cyanobacteria, circadian rhythm is driven by a KaiC protein-based oscillator that …
