WebSep 6, 2024 · The blue-light protein sensors, cryptochromes, compose the widespread class of photoreceptors that regulate processes of development in plants and circadian rhythms in animals and plants. These photoreceptors can also function as magnetoreceptors. WebJun 23, 2024 · The cryptochrome theory of magnetoreception is based on quantum mechanics. Cryptochromes are light-sensitive flavoproteins found in the retinas of birds and several other groups of animals, and they’re known to form a pair of radicals—molecules with unpaired electrons—when exposed to light.
WebWhat is the function of cryptochrome? Cryptochromes (CRY) are photosensory receptors that regulate growth and development in plants and the circadian clock in plants and animals [1, 2]. Plant cryptochromes are best studied in Arabidopsis (Arabidopsis thaliana). The Arabidopsis genome encodes three cryptochrome genes, CRY1, CRY2, and CRY3.

WebThe name cryptochrome was proposed as a portmanteau combining the chromatic nature of the photoreceptor, and the cryptogamic organisms on which many blue-light studies were carried out. The two genes Cry1 and Cry2 code the two cryptochrome proteins CRY1 and CRY2. Cryptochromes are classified into plant Cry and animal Cry.
