WebApr 30, 1999 · In Arabidopsis there are two cryptochrome genes and five genes for the phytochrome photoreceptors. The latter, commonly thought of as red far-red light receptors, also function as blue light photoreceptors . These two classes of photoreceptors overlap in function, with physiological responses such as inhibition of hypocotyl elongation ...

WebDespite much research on the topic, cryptochrome photoreception and phototransduction in Drosophila and Arabidopsis thaliana is still poorly understood. Cryptochromes are known to possess two chromophores: pterin (in the form of 5,10-methenyltetrahydrofolic acid (MTHF)) and flavin (in the form of FAD). The Arabidopsis genome contains three CRY genes, two CRYs (CRY1 and CRY2) of the plant CRY subfamily, and one CRY (CRY3) of the CRY-DASH subfamily. CRY1 and CRY2 have proven signaling activities in photomorphogenesis, while CRY3 repairs cyclobutane pyrimidine dimers in UV-damaged single-stranded … See more As autotrophic organisms, plants use light as their source of energy through photosynthesis.

WebAug 10, 2005 · Abstract. 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 … WebArabidopsis thaliana CRY2 is a blue light photoreceptor which regulates flowering induction and blue light inhibition of hypocotyl elongation ( Yu et al., 2009 ). The photolyase homology (PHR) domain resides in the N-terminus of CRY2 and bears a cofactor, flavin adenine dinucleotide (FAD) ( Bugaj, Choksi, Mesuda, Kane, & Schaffer, 2013; Mas ...
