WebOct 1, 2011 · In plants, the circadian system regulates a vast range of processes, from changes in cytosolic calcium levels and protein phosphorylation to photosynthetic activity and leaf movements [1]. Consistent with the pervasive role of the clock a considerable part of the transcriptome of the model plant, Arabidopsis, is under circadian control 2, 3, 4. WebTranscriptional and posttranscriptional regulation are well-established mechanisms for circadian gene expression. Among the latter, differential messenger RNA (mRNA) …
WebThis mature messenger RNA then leaves the nucleus and enters the cytoplasm. Once in the cytoplasm, the length of time the messenger RNA resides there before being degraded—a characteristic lifespan or “shelf-life” of the molecule called RNA stability—can be altered to control the amount of protein that is synthesized. WebFigure 2. CCL and SEN1 mRNA stability is regulated by the circadian clock. Half-life analysis was carried out as mentioned in ‘‘Materials and Methods’’ in the subjective …
WebRNA blot analysis verified that the abundance of the transcripts arising from these genes oscillates with a period of 21.5 hours in a clock wild-type strain and 29 hours in the long-period clock mutant strain frq7. Genetic mapping through the use of restriction fragment length polymorphisms shows the two genes, ccg-1 and ccg-2, to be unlinked. WebFeb 1, 2011 · Circadian rhythms exist in most living organisms. The general molecular mechanisms that are used to generate 24-hour rhythms are conserved among organisms, although the details vary. These core clocks consist of multiple regulatory feedback loops, and must be coordinated and orchestrated appropriately for the fine-tuning of the 24-hour …
WebMessenger RNA stability is an important control point in modulating gene expression for several reasons. First, the steady-state level of a given mRNA is determined by a balance between its rates of synthesis and degradation. Second, the stability of individual mRNAs can be altered in response to numerous environmental stimuli including carbon ...
