Circadian clocks are found in most eukaryotic organisms. By allowing anticipation of daily and seasonal changes, they enable coordination of metabolism and lifecycle with the natural rhythms of the environment. Plant circadian rhythms are generated by a series of interlocking feedback loops of RNA (ribonucleic acid) and protein expression that respond to environmental cycles of light and temperature. They control essential processes in the plant's development, such as the transition to flowering or growth cessation, and thus influence yield, plant growth and biomass production. Many components of the clock are conserved across a wide variety of plant species and thus research in Arabidopsis translates into an understanding of the clock in agricultural crops or long-living deciduous tree species such as hybrid aspen.
