Prokaryotes have long been thought incapable of expressing circadian (daily) rhythms. Recently, however, such biological ‘clocks’ have been discovered in several species of cyanobacteria. These endogenous timekeepers control gene expression on a global level in cyanobacteria. Even in cyanobacterial cultures that are growing with average doubling times more rapid than one per 24 h, the circadian clock controls gene expression and cell division. We have isolated mutants of the cyanobacterial… Expand

TLDR
A new model for the core clockwork in cyanobacteria proposes that rhythmic changes in the status of the chromosome underlie the rhythms of gene expression and confers adaptive value when different strains compete against each other. Expand

TLDR
Development of a luminescence reporter strain of Synechococcus elongatus PCC 7942 established a model system that ultimately led to the best characterized circadian clockwork at a molecular level. Expand
Circadian programming in cyanobacteria.
TLDR
This work proposes a new model for the core 'clockwork' that implicates rhythmic changes in the status of the chromosome that underly the rhythms of gene expression and identifies three clock genes in the cyanobacteria. Expand
CIRCADIAN PROGRAMS IN CYANOBACTERIA
TLDR
Growth compe- tition experiments demonstrate that the fitness of cyanobacteria is enhanced when the circadian period matches the period of the environmental cycle. Expand
CYANOBACTERIAL CIRCADIAN RHYTHMS.
TLDR
The promise of cyanobacteria as simple models for elucidating the biological clock mechanism is being fulfilled, as mutants affected in period, rhythm generation, and rhythm amplitude, isolated through the use of real time reporters of gene expression, have implicated genes involved in these aspects of the clock.

Circadian programs in cyanobacteria: adaptiveness and mechanism.
TLDR
Three genes have been identified that specifically affect circadian phenotypes that appear to interact with each other and form an autoregulatory feedback loop in cyanobacteria. Expand

This work surveys studies of the circadian control of cell division in eukaryotic microorganisms and introduces recent progress on understanding the interaction between circadian rhythms and cell division cycles in cyanobacteria. Expand
Circadian Programmes in Cyanobacteria
Cyanobacteria are prokaryotes that express circadian (daily) rhythms. In rhythmic environments, the fitness of cyanobacteria is improved when this clock is operational and when its circadian periodExpand
A Cyanobacterial Circadian Clockwork
TLDR
The cyanobacterial circadian system is brought to the brink of explaining heretofore unexplainable biochemical characteristics of a circadian oscillator: the long time constant, precision, and temperature compensation. Expand

TLDR
The conjunction of structural information on essential clock proteins with a defined system that reconstitutes circadian oscillations in vitro leads to a turning point whereby biophysical and biochemical approaches bring analyses of circadian clock-work to an unprecedented level of molecular detail.

TLDR
It is found that populations dividing at rates as rapid as once per 10 h manifest circadian gating of cell division, since phases in which cell division slows or stops recur with a circadian periodicity. Expand
