摘　　要：Dear Editor,Cryptochromes(CRYs)are blue-light photoreceptors that mediate various light responses in plants(Wang and Lin,2020;Wang et al.,2021).Two CRYs have been identified in Arabidopsis thaliana(At),AtCRY1 and AtCRY2,which mediate hypocotyl elongation and floral initiation(Ahmad and Cashmore,1993;Guo et al.,1998).CRYs are comprised of a conserved N-terminal photolyase-related(PHR)domain for chromophore FAD binding and a C-terminal domain(CCE)of variable length,and different plant CRYs have been found to exert overlapping biological functions(Lin et al.,1998;Rosenfeldt et al.,2008).
