Spectroscopic investigation of phytochromes and NIR fluorescent variants
… [IR]) were used for the investigation of phytochromes. Phytochromes are bistable photoreceptor proteins that bind bilins (BV, PCB, PΦB) as chromophores. Various plant, cyanobacterial, and bacterial variants regulate biological processes through the light dependent switching between …

Structural Features of Bacteriophytochromes. Photoactivated Proteins studied by Serial Femtosecond Crystallography
… detecting photoreceptor proteins are called phytochromes and are present in plants, fungi and bacteria. A chromophore, converts the light signal into a structural change in the protein that alter its biochemical properties and thereby control developmental processes in the organism. A …

Analysis of phytochrome signaling pathways in Zea mays
Phytochromes are photoreceptors that mediate red and far-red light signaling and control growth and development of plants in response to different light conditions. The genome of Arabidopsis, a dicot, contains five members of the phytochrome family, phyA-phyE. In contrast, genomes of monocots …

Is Alnus viridis 'a' glacial relict in the Black Forest ?
… action is complemented by UV-A/BL receptor(s). Phytochromes are not involved. A similar result is observed for the anthocyanins one of the end products of the flavonoid biosynthesis. In contrast, phytochromes are clearly involved in the regulation of flavonoid induction in the cotyledons. The …

Understanding and engineering photoresponses in Arabidopsis thaliana
… are the red and far-red light sensitive phytochromes, the blue light sensitive cryptochromes, phototropins and zeitlupe family and the UV-B receptor UVR8. The role of phototropins in the maintenance of circadian rhythms in the chloroplast has been recently identified, suggesting the …

Structure-function analysis of phototropin receptor kinases
… families identified in plants include the phytochromes, which are most sensitive to red and far-red light, and the cryptochromes and phototropins, which are UV-A and blue light receptors. Additional photosensors, including the recently identified ZEITLUPE/ADAGIO family, have roles in …

The Function and Regulation of Photobodies in Phytochrome Signaling
… the red- and far-red light-sensing phytochromes (phys) are arguably the best studied, but the earliest events in the phy signaling pathway remain poorly understood. One of the earliest phy signaling events is the translocation of photoactivated phys from the cytoplasm to the nucleus, …

Investigation of phototropin blue light receptor function and signalling in arabidopsis
… in two regions of the electromagnetic spectrum. Phytochromes are light sensors for the red and far-red wavelengths of light while cryptochromes, phototropins and members of the ZTL/ADO family respond to blue and UV-A wavelengths of light. Phototropins are UV-A/blue-light receptor kinases found …
