COP1 works hard while seedlings are in the dark to keep photomorphogenesis genes turned off. (sciencemag.org)
The master regulator of this so - called photomorphogenesis is a protein called COP1, discovered a decade ago by Xing - Wang Deng's team at Yale University. (sciencemag.org)
When seedlings encounter light, supplies of COP1 dwindle in the nucleus, allowing transcription factor levels to rise and switch on photomorphogenesis genes. (sciencemag.org)
