Rapid decline in nuclear costitutive photomorphogenesis1 abundance anticipates the stabilization of its target elongated hypocotyl5 in the light

Plant Physiol. 2014 Mar;164(3):1134-8. doi: 10.1104/pp.113.234245. Epub 2014 Jan 16.

Abstract

The classic view is challenged that the migration of the repressor of photomorphogenesis COP1 from the nucleus to the cytoplasm is too slow to participate in light-mediated developmental events.
