Blue light receptors in plants
WebMar 3, 1998 · Cryptochrome is a group of flavin-type blue light receptors that regulate plant growth and development. The function of Arabidopsis cryptochrome 2 in the early photomorphogenesis of seedlings was studied by using transgenic plants overexpressing CRY2 protein, and cry2 mutant plants accumulating no CRY2 protein.

WebAs light filters through the canopy and the blue and red wavelengths are absorbed, the spectrum shifts to the far-red end, shifting the plant community to those plants better adapted to respond to far-red light. …
WebDec 16, 2024 · Cryptochromes set the plant’s circadian rhythm (the 24-hour activity cycle) using blue light receptors. There is some evidence that cryptochromes work by sensing light-dependent redox reactions and that, together with phototropins, they mediate the phototropic response. Key Points WebJun 8, 2024 · Phototropins are protein-based receptors responsible for mediating the phototropic response in plants. Like all plant photoreceptors, phototropins consist of a protein portion and a light-absorbing portion, …

Recent studies have identified three such receptors: cryptochrome 1, … WebFeb 10, 2016 · ZEITLUPE (ZTL), FLAVIN-BINDING, KELCH REPEAT, F-BOX1 (FKF1) and LOV KELCH PROTEIN2 (LKP2) group proteins are blue light sensors that have LOV, F-box and Kelch-repeat domains and form signaling complexes with factors involved in the regulation of the circadian clock and photoperiodic flowering (Zoltowski and Imaizumi …
WebCryptochromes receptors cause plants to respond to blue light via photomorphogenesis. They help control seed and seedling development, as well as the switch from the vegetative to the flowering stage of development. In Arabidopsis, it has been shown that cryptochromes controls plant growth during sub-optimal blue-light conditions.
