They found an "alarm clock" in plants: it helps them sleep the right amount of time

The ability to predict sunrise and estimate the length of the night and based on this

control the metabolic process - essential for the survival of plants and their development. It depends on the biological timekeeper or the circadian rhythm of the circadian.

The authors compared an open metabolic signal that plants have with an alarm clock: set before bed to provide the necessary amount of energy to survive the night.

To understand how sugars change the circadian clock, the researchers measured gene expression in seedlings by altering photosynthesis or sugar storage.

They discovered a set of genes that are regulatedchemical compound: superoxide - a molecule associated with metabolic activity. Most of these genes are active in the evening: they turn on key genes that operate in circadian rhythms.

The authors of the study found that by suppressing superoxide production, they also suppressed the effect of sugar on these circadian clock genes in the evening.
