The role of TOR in regulation of Arabidopsis circadian oscillators
Plants possess internal circadian oscillators, containing a series of gene expression feedback loops. These oscillators enable plants to coordinate their biological processes with the light- dark cycles of the Earth. Arabidopsis circadian oscillators are entrained by internal and external cues, …

Mathematical modelling of the light input signalling pathways to the Arabidopsis circadian oscillators
… of which regulate the dynamics of Arabidopsis circadian oscillators. Mechanistically, light regulation of the circadian oscillator occurs through multiple synergistic and/or independent molecular signalling pathways. Physiologically, it manifests as entrainment under periodic environments and …

Genetic and Biochemical Studies on Protein Phosphorylation in the Circadian Clock of Drosophila Melanogaster
<p>Circadian rhythms in physiology and behavior are observed in almost all phyla. Genetically encoded internal clocks generate such rhythms. Identification of gene products required for the generation and maintenance of endogenous circadian near 24-hr rhythms has led to a paradigm of multiple …

Is there a role for NF-κB in the suprachiasmatic circadian clock?
Circadian rhythms are recurring patterns in behavioural, physiological, and other parameters that display periods of approximately every twenty four hours. The molecular basis of the circadian timekeeping involves clock genes which act as transcription factors in a serious of feedback loops. …

Molecular and Genetic Analysis of Neuropeptide Signalling in Mammalian Circadian Timekeeping
… co-ordinating the multitude of cell-autonomous circadian oscillators across the body to ensure internal synchrony, as well as maintaining an adaptive phase relationship with the light-dark cycle via projections from the retina. Intercellular communication between SCN clock neurons synchronises …

Investigation of natural and synthetic coupling of the circadian clock in the cyanobacterium Synechococcus elongatus
… owing to its possession of a simple, yet robust circadian clock, is a well-studied model for microbial chronobiology. However, historical tool limitations have left much still to learn about this clock, including definitive answers as to whether it exhibits coupling. During this PhD project, the …
