Light receptors
WebJan 1, 2001 · The first blue-light receptors to be identified were the two cryptochromes, chromoproteins that mediate several responses. More recently, another blue-light-absorbing chromoprotein, phototropin, has been identified as a photoreceptor mediating phototropism. WebFeb 27, 1998 · eLetters (0) Abstract The shift in plants from vegetative growth to floral development is regulated by red–far-red light receptors (phytochromes) and blue–ultraviolet A light receptors (cryptochromes). A mutation in the Arabidopsis thaliana CRY2 gene encoding a blue-light receptor apoprotein (CRY2) is allelic to the late-flowering mutant, fha.

WebReceptors are protein molecules inside the target cell or on its surface that receive a chemical signal. Chemical signals are released by signaling cells in the form of small, usually volatile or soluble molecules called ligands. A ligand is a molecule that binds another specific molecule, in some cases, delivering a signal in the process.
