Circadian clocks regulate the gene expression, metabolism and behaviour of most eukaryotes, controlling an orderly succession of physiological processes that are synchronised with the environmental day/night cycle. Central circadian pacemakers that control animal behaviour are located in the brains of insects and rodents, but the location of such a pacemaker has not been determined in plants. Peripheral plant and animal tissues also maintain circadian rhythms when isolated in culture, indicating that these tissues contain circadian clocks. The degree of autonomy that the multiple, peripheral circadian clocks have in the intact organism is unclear.
