Photoperiodic growth control in perennial trees

Plant Signal Behav. 2015;10(12):e1087631. doi: 10.1080/15592324.2015.1087631.


Plants have to cope with changing seasons and adverse environmental conditions. Being sessile, plants have developed elaborate mechanisms for their survival that allow them to sense and adapt to the environment and reproduce successfully. A major adaptive trait for the survival of trees of temperate and boreal forests is the induction of growth cessation in anticipation of winters. In the last few years enormous progress has been made to elucidate the molecular mechanisms underlying SDs induced growth cessation in model perennial tree hybrid aspen (Populus tremula × P. tremuloides). In this review we discuss the molecular mechanism underlying photoperiodic control of growth cessation and adaptive responses.

Keywords: adaptation; growth cessation; hybrid aspen; perennial trees; photoperiod.
