WebMolecular models for the circadian oscillator have now been elucidated in Drosophila, Neurospora, mice and cyanobacteria. All share a similar feedback structure, but key proteins in each of the oscillators are different. A plant clock model has yet to be proposed, but clock mutants of Arabidopsis are expected to reveal key proteins in the ... WebA 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 clones of chemically mutagenized bioluminescent cells, 12 mutants were isolated that exhibit a broad spectrum of periods (between 16 and 60 hours), and 5 mutants were …
