Plants can appraise the time using sugars

A new study by an international team of scientists, including Dr. Antony Dodd of the University of Bristol’s School of Biological Sciences, has discovered that plants calibrate their daily circadian rhythm to the cycle of day and night by measuring the volume of sugars in their cells. Plants, animals, fungi and some bacteria can estimate the time of day through their circadian rhythms. These rhythms are regulated by an internal ‘circadian clock’, and how these clocks operate is a topic of importance for both agriculture and medicine. For example, changes in circadian rhythms have contributed to the domestication of crops.
