The genetics of phototransduction and circadian rhythms in Arabidopsis

A J Millar, S A Kay

Research output: Contribution to journalArticlepeer-review


A wide range of biological processes, in all eukaryotes and in some prokaryotes, are controlled by rhythms with a period close to 24 hours. The circadian oscillator, which is responsible for generating these rhythms, is controlled by light signals that maintain its synchrony with the environmental day/night cycle. Higher plants exhibit many circadian rhythms, including rhythms in the transcription of specific genes. Molecular tools derived from such clock-controlled genes have led to the identification of several circadian rhythm mutants in the genetic model, Arabidopsis thaliana. The extensive understanding of photoperception in this species will make it a powerful system with which to investigate the light regulation of circadian rhythms. We compare Arabidopsis rhythms to the results from other systems, and discuss these data with respect to the current phototransduction models.
