PHOTOCHRONO · Molecular mechanisms of circadian gating interconnecting light and clock signaling in Arabidopsis

Lines connect the coordinator with its partners.

Project objective

The periodic succession of days and nights is an eternally recurring environmental factor ever since life has appeared on the Earth. It is postulated that (i) organisms possessing the ability to adapt to the predictable changes of the environment have an evolutionary advantage and that (ii) this benefit has promoted the development of timekeeping mechanisms (endogenous clocks). The biological clocks that generate and maintain oscillations of many physiological and molecular processes with a period length close to 24 h are also referred to as circadian clocks. In a canonical circadian system, the central oscillator generates an oscillation with a period of -24 h, and regulates overt rhythms through the output pathway. Light signals absorbed by photoreceptors reach the central oscillator through the input pathway and reset its phase to the periodic environmental changes. The oscillator feeds back to the activity of the light input through rhythmic gating of light input components. Due to the intimate
