Circadian Rhythms in Plants.
Circadian rhythms, endogenous rhythms with periods of approximately 24 h, are widespread in nature. Although plants have provided many examples of rhythmic outputs and our understanding of photoreceptors of circadian input pathways is well advanced, studies with plants have lagged in the identification of components of the central circadian oscillator. Nonetheless, genetic and molecular biologi...
متن کاملThe physiology of circadian rhythms in plants
Circadian rhythms regulate many aspects of plant physiology including leaf, organ and stomatal movements, growth and signalling. The genetic identity of some of the components of the core circadian oscillator has recently become known. Similarly, the photoperception and phototransduction pathways that entrain the oscillator to the day and night cycle are being determined. Less clear are the pat...
متن کاملCircadian rhythms and post-transcriptional regulation in higher plants
The circadian clock of plants allows them to cope with daily changes in their environment. This is accomplished by the rhythmic regulation of gene expression, in a process that involves many regulatory steps. One of the key steps involved at the RNA level is post-transcriptional regulation, which ensures a correct control on the different amounts and types of mRNA that will ultimately define th...
متن کاملCircadian rhythms.
1997 marks the 25th anniversary of the discovery of the master circadian pacemaker in mammals in the hypothalamic suprachiasmatic nucleus. Remarkable progress has been made over the last 25 years in elucidating the physiological mechanisms involved in the entrainment, generation and expression of circadian rhythms at the cellular and systems levels. The recent discovery and cloning of the first...
متن کاملCircadian rhythms.
Circadian rhythms are a ubiquitous adaptation of eukaryotic organisms to the most reliable and predictable of environmental changes, the daily cycles of light and temperature. Prominent daily rhythms in behavior, physiology, hormone levels and biochemistry (including gene expression) are not merely responses to these environmental cycles, however, but embody the organism's ability to keep and t...
