Positive phototropism is the process through which plants orient their organs towards a directional light source. While the blue light receptors phototropins (phot) play a major role in phototropism towards blue (B) and ultraviolet (UV) radiation, recent research showed that the UVB light receptor UVR8 also triggers phototropism towards UVB. In addition, new details of the molecular mechanisms underlying the activity of these receptors and interaction with other environmental signals have emerged in the past years. In this review we summarize the current knowledge about hypocotyledoneous and inflorescence stem growth reorientation towards B and UVB, with focus on the molecular mechanisms.

Cryptochromes (CRYs) are flavin-binding proteins that sense blue and near-ultraviolet light and participate in the photoreactions of organisms and the regulation of biological clocks. In this study, t...
Planarian freshwater flatworms have the unique ability to regenerate due to stem cell activity. The process of regeneration is extremely sensitive to various factors, including light radiation. Here, ...
Photostimulation has been widely used in neuromodulation. However, existing optogenetics techniques require genetic alternation of the targeted cell or tissue. Here, we report that neural stem cells (...
Blue light is an important environmental factor that induces mushroom primordium differentiation and fruiting body development. Although blue-light treatment has been applied for the production of oys...
The purpose was to investigate the effect of daylight-intensity blue light on F. solani isolated from the cornea of patients with fungal keratitis. Spore suspensions of 5 F. solani strains (one standa...
RATIONALE: Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy. Sometimes the transplanted cells from a donor are rejected by the b...
To compare the effect on blood retinal barrier disruption 3 and 12 months after implantation of either a blue light filtering intraocular lens(blue-filtering IOL) or an ultraviolet light f...
Hand and foot skin diseases, such as dermatitis and psoriasis, that do not respond to topical creams can be treated with ultraviolet light therapy. Topical psoralen plus ultraviolet A (PU...
RATIONALE: Ultraviolet light therapy uses light and drugs that make cancer cells more sensitive to light to kill tumor cells. It is not yet known whether ultraviolet light therapy is more ...
One of the most frequently investigated hypothesis of the pathophysiology underlying Seasonal Affective Disorder(SAD) or so called winter depression is a disturbance of circadian rhythms. ...
Blue-light receptors that regulate a range of physiological responses in PLANTS. Examples include: PHOTOTROPISM, light-induced stomatal opening, and CHLOROPLAST movements in response to changes in light intensity.
The use of ultraviolet electromagnetic radiation in the treatment of disease, usually of the skin. This is the part of the sun's spectrum that causes sunburn and tanning. Ultraviolet A, used in PUVA, is closer to visible light and less damaging than Ultraviolet B, which is ionizing.
Microscopy of specimens stained with fluorescent dye (usually fluorescein isothiocyanate) or of naturally fluorescent materials, which emit light when exposed to ultraviolet or blue light. Immunofluorescence microscopy utilizes antibodies that are labeled with fluorescent dye.
The metal-free blue phycobilin pigment in a conjugated chromoprotein of blue-green algae. It functions as light-absorbing substance together with chlorophylls.
Plant proteins that mediate LIGHT SIGNAL TRANSDUCTION. They are involved in PHOTOTROPISM and other light adaption responses during plant growth and development . They include the phototropins, phytochromes (PHYTOCHROME), and members of the ubiquitous cryptochrome family.
