摘 要：Cryptochromes (CRY) are blue light receptors that share sequence similarity to pho-tolyases, flavoproteins that catalyse the repair of UV light-damaged DNA. Transgenic Arabidopsis seedlings expressing the C-terminal domains of the Arabidopsis CRY fused to (-glucuronidase (GUS) display a constitutive photomorphogenic phenotype (COP pheno-type), indicating that the signaling mechanism of Arabidopsis CRY is mediated through
