Cryptochromes (CRY) are photolyase-like flavoproteins that have been found in all evolutionary lineages. Plant and animal cryptochromes are no longer DNA repairing enzymes but they apparently gained other biochemical functions in evolution. Plant cryptochromes are UV-A/blue light photoreceptors and play a pivotal role in plant growth and development, whereas animal cryptochromes act as either photoreceptors or transcription regulators. The first cryptochrome gene was isolated from Arabidopsis thaliana, which regulate stem growth, flowering time, stomatal opening, circadian clock, and other light responses. Cryptochromes are also found in all major crops investigated, with additional functions discovered, such as seed germination, leaf senescence, and stress responses. In this chapter, we will review some aspects of cryptochrome-mediated light responses in plants. Readers are referred to other review articles for photochemistry and signal transduction mechanism of plant cryptochromes.
