The organization of biological activities into daily cycles is universal in organisms as diverse
as cyanobacteria, fungi, algae, plants, flies, birds and man. Comparisons of circadian clocks …

We thank members of the Golden laboratory for helpful discussion and Blake Trial and Mizu …

… & SS Golden, unpublished data). We suggest that the difference between mRNA levels and
bioluminescence occurs because transcription and message degradation are uncoupled in …

In some organisms longevity, growth, and developmental rate are improved when they are
maintained on a light/dark cycle, the period of which “resonates” optimally with the period of …

Cyanobacteria are the simplest organisms known to have a circadian clock. A circadian clock
gene cluster kaiABC was cloned from the cyanobacterium Synechococcus. Nineteen clock …

We have used a luciferase reporter gene and continuous automated monitoring of
bioluminescence to demonstrate unequivocally that cyanobacteria exhibit circadian behaviors that …

Publisher Summary This chapter describes methods for the direct genetic engineering of
the cyanobacterial chromosome and techniques for the analysis of DNA and RNA from the …

We wanted to identify genes that are controlled by the circadian clock in the prokaryotic
cyanobacterium Synechococcus sp. strain PCC 7942. To use luciferase as a reporter to monitor …

A diverse set of circadian clock mutants was isolated in a cyanobacterial strain that carries a
bacterial luciferase reporter gene attached to a clock-controlled promoter. Among 150,000 …

The circadian oscillator of the cyanobacterium Synechococcus elongatus, like those in
eukaryotes, is entrained by environmental cues. Inactivation of the gene cikA (circadian input …
