Plant blue-light receptors.
Plants have several blue-light receptors, which regulate different aspects of growth and development. Recent studies have identified three such receptors: cryptochrome 1, cryptochrome 2 and phototropin. Cryptochromes 1 and 2 are photolyase-like receptors that regulate hypocotyl growth and flowering time; phototropin mediates phototropism in response to blue light. In addition, phytochrome A has...
متن کاملBlue light-induced chloroplast relocation.
Chloroplast relocation movement is induced by blue light in most plants tested. Under weak light, chloroplasts move toward a brighter area in a cell (called low-fluence-rate response or accumulation movement), but they avoid strong light and move away from the light (called high-fluence-rate response or avoidance movement). Recently, mutants deficient in the chloroplast avoidance movement were ...
متن کاملBlue light hazard and aniridia.
The fundi of three patients with aniridia were photographed with a 470 nm illuminating light source. No apparent change in contrast was observable throughout the macular region. This would suggest an absence of the macular pigment. The likelihood of aniridics being more susceptible than normal persons to blue light damage is discussed.
متن کاملHazards of solar blue light.
Short-wavelength visible light (blue light) of the Sun has caused retinal damage in people who have stared fixedly at the Sun without adequate protection. The author quantified the blue-light hazard of the Sun according to the International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines by measuring the spectral radiance of the Sun. The results showed that the exposure limi...
