Cryptochromes, phytochromes, and COP1 regulate light-controlled stomatal development in Arabidopsis.

The Plant cell - 1 Sept 2009

Abstract excerpt

In Arabidopsis thaliana, the cryptochrome (CRY) blue light photoreceptors and the phytochrome (phy) red/far-red light photoreceptors mediate a variety of light responses. COP1, a RING motif-containing E3 ubiquitin ligase, acts as a key repressor of photomorphogenesis. Production of stomata, which mediate gas and water vapor exchange between plants and their environment, is regulated by light and involves phyB and...
