Short day-mediated cessation of growth requires the downregulation of AINTEGUMENTALIKE1 transcription factor in hybrid aspen.
Day length is a key environmental cue regulating the timing of major developmental transitions in plants.For example, in perennial plants such as the long-lived trees of the boreal forest, exposure to short days (SD) leads to the termination of meristem activity and bud set (referred to as growth cessation).The mechanism underlying SD-mediated indu
