The Circadian Clock Influences the Long-Term Water Use Efficiency of Arabidopsis.

In plants, water use efficiency (WUE) is a complex trait arising from numerous physiological and developmental characteristics. Here, we investigated the involvement of circadian regulation in long-term WUE in Arabidopsis () under light and dark conditions. Circadian rhythms are generated by the circadian oscillator, which provides a cellular measure of the time of day.
