What is period and Cryptochrome? Period stretches out as it ’embraces’ Cryptochrome. WebDec 27, 2010 · Cryptochrome (CRY) is a flavoprotein that regulates growth and development in plants in response to blue light, functions as a circadian photoreceptor in Drosophila and other insects, and acts as a core component of the molecular clock in mammalian organisms (1–4).Despite extensive research on CRYs photosensory function …
WebDec 30, 2008 · Light and the circadian clock often regulate gene expression of cryptochromes. For example, the mRNA expression of cryptochrome genes is regulated by the circadian clock in Arabidopsis, tomato, and pea (13, 17, 18), and by blue light in Brassica ().Most studies of the cryptochrome gene expression are limited to the level of mRNA, … WebOct 14, 2024 · In parallel, blue-light-activated cryptochrome 2 (CRY2) ...

Cryptochromes (from the Greek κρυπτός χρώμα, "hidden colour") are a class of flavoproteins found in plants and animals that are sensitive to blue light. They are involved in the circadian rhythms and the sensing of magnetic fields in a number of species. The name cryptochrome was proposed as a portmanteau … See more Although Charles Darwin first documented plant responses to blue light in the 1880s, it was not until the 1980s that research began to identify the pigment responsible.
