2020.05.27 Circadian oscillation of a cyanobacterium doesn’t need all three Kai proteins to keep going Circadian oscillation of a cyanobacterium doesn’t need all three Kai proteins to keep going Inactivating KaiA does not stop but damps circadian oscillations of the cyanobacterial‘ circadian clock (A). The amplitude of the damped oscillation is elevated by resonance with external cycles (B). Credit:Iwasaki Laboratory, Waseda University Overturning conventional knowledge, what these scientists have discovered about the circadian oscillations of a cyanobacterium could lead to unveiling a great mystery with physiological and evolutionary significance in the future. <Readmore>
