Circadian clocks synchronize inteal physiological responses to occur at the most optimal time of the day.In plants,hormone signaling is under the control of this clock.It has been previously shown that the circadian clock moderates the plants sensitivity to gibberellin (GA) by regulating the expression of GA receptors.Recently,two papers by Nohales and Kay (2019) and Park et al.(2020) revealed that posttranslational regulation of DELLA proteins by the circadian clock also contributes to timing when the plant is most sensitive to GA.
