PLANT SCIENCES: A CONSTANS Experience Brought to Light
John Klejnot and Chentao Lin
Many plants bloom in the Spring in response to seasonal changes of day length, a phenomenon called photoperiodism. In their Perspective, Klejnot and Lin discuss new work that sheds light on photoperiodic flowering (Valverde et al.). They explain that light photoreceptors modulate production of the CONSTANS transcription factor such that CONSTANS levels drop during the night due to proteolysis and increase during the day due to stabilization of this transcription factor.
