Nature's Master of Ceremony: The <i>Populus</i> Circadian Clock as Orchestratot of Tree Growth and Phenology.

ABSTRACT: Understanding the timely regulation of plant growth and phenology is crucial for assessing a terrestrial ecosystem's productivity and carbon budget. The circadian clock, a system of genetic oscillators, acts as 'Master of Ceremony' during plant physiological processes. The mechanism is particularly elusive in trees despite its relevance. The primary and secondary tree growth, leaf senescence, bud set, and bud burst timing were investigated in 68 constructs transformed into Populus hybrids and compared with untransformed or transformed controls grown in natural or controlled conditions. The results were analyzed using generalized additive models with ordered-factor-smooth interaction smoothers. This meta-analysis shows that several genetic components are associated with the clock.
