“…However, the overexpression of PtCO1 and PtCO2 individually or together affects poplar tree size without impacting reproductive onset, spring bud break, or fall dormancy ( Hsu et al 2011 ). All these examples illustrate the complexity of the control of photoperiod-dependent flowering in trees because photoperiod affects not only the transition from vegetative to reproductive phase, as in herbaceous plants, but also bud dormancy ( Hussain et al 2022 ). These 2 complex developmental processes directly influence the year-round cyclic regulation of flowering, which varies between trees adapted to different climates ( Sun et al 2022 ).…”

How does a plant detect the changing seasons and make important developmental decisions accordingly? How do they incorporate daylength information into their routine physiological processes? Photoperiodism, or the capacity to measure the daylength, is a crucial aspect of plant development that helps plants determine the best time of the year to make vital decisions, such as flowering. The protein CONSTANS (CO) constitutes the central regulator of this sensing mechanism, not only activating florigen production in the leaves but also participating in many physiological aspects in which seasonality is important. Recent discoveries place CO in the center of a gene network that can determine the length of the day and confer seasonal input to aspects of plant development and physiology as important as senescence, seed size, or circadian rhythms. In this review, we discuss the importance of CO protein structure, function, and evolutionary mechanisms that embryophytes have developed to incorporate annual information into their physiology.
