Circadian control of messenger rna stability

Plants, like many other organisms, have internal clocks that command biological rhythms with a period close to 24 h. These rhythms provide selective advantages because they allow anticipation of the daily changes in environmental conditions (Ouyang et al., 1998; Green et al., 2002). Examples of processes … See more Although it has become clear that posttranscriptional mechanisms contribute significantly to CCG expression, prior to this work, the evidence for regulation at the level of mRNA … See more We would like to thank Lan Xue (Statistical Consulting Service, Department of Statistics, Michigan State University) for help with the statistical analysis of mRNA half-lives. See more WebAmong the latter, differential messenger RNA (mRNA) stability has been hypothesized to control gene expression in response to the clock. However, direct proof that the rate of …
