英文摘要	Cryptochromes (cry) are blue light photoreceptors that mediate various light-induced responses in plants and animals. arabidopsis cry (cry1 and cry2) functions through negatively regulating constitutive photomorphogenic (cop) 1, a repressor of photomorphogenesis. water evaporation and photosynthesis are regulated by the stomatal pores in plants, which are closed in darkness but open in response to blue light. there is evidence only for the phototropin blue light receptors (phot1 and phot2) in mediating blue light regulation of stomatal opening. here, we report a previously uncharacterized role for arabidopsis cry and con in the regulation of stomatal opening. stomata of the cry1 cry2 double mutant showed reduced blue light response, whereas those of the cry1-overexpressing plants showed hypersensitive response to blue light. in addition, stomata of the phot1 phot2 double mutant responded to blue light, but those of the cry1 cry2 phot1 phot2 quadruple mutant hardly responded. strikingly, stomata of the cop1 mutant were constitutively open in darkness and stomata of the cry1 cry2 cop1 and phot1 phot2 cop1 triple mutants were open as wide as those of the cop1 single mutant under blue light. these results indicate that cry functions additively with phot in mediating blue light-induced stomatal opening and that con is a repressor of stomatal opening and likely acts downstream of cry and phot signaling pathways.
