Life on earth is subject to daily and predictable fluctuations in light intensity, temperature,
and humidity created by rotation of the earth. Circadian rhythms, generated by a circadian …

Circadian regulation produces a biological measure of time within cells. The daily cycle in
the availability of light for photosynthesis causes dramatic changes in biochemical …

Circadian clocks are self-sustained biological oscillators that can be entrained by
environmental cues. Although this phenomenon has been studied in many organisms, the …

The cyanobacterium Synechococcus elongatus is a model organism for the study of
circadian rhythms. It is naturally competent for transformation—that is, it takes up DNA from …

Synechococcus elongatus PCC 7942 is a genetically tractable model cyanobacterium that
has been engineered to produce industrially relevant biomolecules and is the best-studied …

Bacterial quinones are lipophilic redox compounds involved in important cellular roles such
as electron transport in respiratory and photosynthetic chains. However, a growing body of …

The cyanobacterial thylakoid membrane represents a system that can carry out both
oxygenic photosynthesis and respiration simultaneously. The organization, interactions and …

Circadian oscillators are networks of biochemical feedback loops that generate 24-hour
rhythms in organisms from bacteria to animals. These periodic rhythms result from a …

Circadian rhythms enable cells and organisms to coordinate their physiology with the cyclic
environmental changes that come as a result of Earth's light/dark cycles. Cyanobacteria …

Modern systems biology permits the study of complex networks, such as circadian clocks,
and the use of complex methodologies, such as quantitative genetics. However, it is difficult …
