WebJul 8, 2015 · For over 100 years it has been known that a blue light photoreceptor regulates growth and development in plants under low-light conditions. These photoreceptors were termed cryptochomes (CRYs) because of their importance in cryptogamic plants and the cryptic aspects of their function and photochemistry ( 1, 2 ). WebDec 1, 2011 · The photoexcitation mechanism of CRYs is not fully understood, although it has been proposed to involve light-dependent electron transport [46].The CRY apoprotein contains two domains: the N-terminal photolyase-homologous region (PHR) domain of approximately 500 residues, and the C-terminal cryptochrome C-terminal extension …
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. WebMar 26, 2024 · Cryptochromes (CRYs) entrain the circadian clocks of plants and animals to light. Irradiation of the Drosophila cryptochrome (dCRY) causes reduction of an oxidized flavin cofactor by a chain of conserved tryptophan (Trp) residues. However, it is unclear how redox chemistry within the Trp chain couples to dCRY-mediated signaling.
