| Outline of Final Research Achievements |
The unicellular cyanobacterium, Synechococcus provides an excellent model to study circadian systems. We have demonstrated (i) Hopf bifurcation underlying the in vitro reconstituted KaiC phosphorylation cycle at low temperature, ensuring damped oscillation resonated to external 24-h period cycles, (ii) a damped oscillation in transcriptional regulation even in the absence of KaiA, and (iii) circadian UV-resistance rhythms associated with carbon metabolism.
