Entrainment of Circadian Rhythms to Environmental cycles in Lactuca sativa L. - Characteristics of Circadian Rhythms in Lettuce -

The circadian clock that exists in terrestrial organisms to trigger various physiological phenomena within a period of approximately 24 hours. This approximate time range of 24 hr periodicity is called the “circadian rhythm”. Recently, the studies of circadian rhythms suggest that the control of circadian rhythm can contribute to improvement of the productivity of plant growth (called circadian resonance). Therefore, it is necessary to investigate the features of circadian rhythm and to search for optimal light conditions that best suit plant cultivation. In this study, we analyzed the characterization of circadian rhythms through a luciferase luminescence assay in Lactuca sativa L.
