Temperature compensation and temperature entrainment of the chick pineal cell circadian clock.
We have used an in vitro model system of the circadian clock, dispersed chick pineal cells, to examine the effects of temperature on the circadian clock of a homeotherm. This preparation enabled us to isolate a circadian clock from in vivo homeostatic temperature regulation and expose cells to both constant temperatures and abrupt temperature changes. By manipulating the temperature of the pine...
متن کاملTemperature Entrainment of the Arabidopsis Circadian Clock
Most eukaryotic organisms as well as some prokaryotes (cyanobacteria) have an endogenous circadian clock that keeps track of the earth’s 24-h day/night cycle and regulates the activity of numerous metabolic pathways. The existence of the circadian clock as an endogenous feature of organisms and not merely a response to the presence or absence of sunlight was recognized in plants as early as the...

متن کاملTemperature compensation and temperature sensation in the circadian clock.
All known circadian clocks have an endogenous period that is remarkably insensitive to temperature, a property known as temperature compensation, while at the same time being readily entrained by a diurnal temperature oscillation. Although temperature compensation and entrainment are defining features of circadian clocks, their mechanisms remain poorly understood. Most models presume that multi...
متن کاملTemperature-compensated circadian clock in the pineal of Anolis.
The pineal organ of the lizard Anolis carolinensis can be maintained for up to 10 days in superfused organ culture. During this time it synthesizes and releases melatonin into the medium flowing slowly over it. Collection of timed aliquots of medium and subsequent analysis for melatonin by radioimmunoassay reveal circadian rhythms of melatonin output by the isolated pineal. These rhythms persis...
