Endogenous clock-mediated regulation of intracellular oxygen dynamics is essential for diazotrophic growth of unicellular cyanobacteria
Abstract The discovery of nitrogen fixation in unicellular cyanobacteria provided the first clues for the existence of a circadian clock in prokaryotes.However, recalcitrance to genetic manipulation barred their use as model systems for deciphering the clock function.Here, we explore the circadian clock in the now genetically amenable Cyanothece 51
