Time to Network : The Molecular Blueprint of the Circadian Timing System in Plants

Abstract

Plants are exposed to periodic changes of light and darkness in their habitats through the Earth’s rotation around its axis. Accordingly, plants have evolved an endogenous system to schedule their day in synchrony with their surroundings. Here, we review the blueprint of the core clockwork in plants and how the core clockwork orchestrates time-of-day-specific gene expression programmes.
