Circadian rhythms were first observed in plants. Molecular genetic studies since 1991 have identified a complex gene regulatory network in the plant circadian clock. Systems biology approaches since 2005 have used mathematical models to understand its mechanism. In 2011, the paradigm of a clock based on transcriptional regulation was called into doubt, by a rediscovery of non-transcriptional timing. The new data suggest that the non-transcriptional clock may be ancestral, and common to all eukaryotes, whereas transcriptional clock circuits evolved much more recently.
