Phototropins promote plant growth in response to blue light in low light environments.
Phototropins (phot1 and phot2) are plant-specific blue light receptors for phototropism, chloroplast movement, leaf expansion, and stomatal opening. All these responses are thought to optimize photosynthesis by helping to capture light energy efficiently, reduce photodamage, and acquire CO2. However, experimental evidence for the promotion of plant growth through phototropins is lacking. Here, ...
متن کاملMarkus Grebe: Bringing plant polarity to light
Grebe studies the establishment and maintenance of cell and tissue polarity in plants.
متن کاملFormation and Change of Chloroplast-Located Plant Metabolites in Response to Light Conditions
Photosynthesis is the central energy conversion process for plant metabolism and occurs within mature chloroplasts. Chloroplasts are also the site of various metabolic reactions involving amino acids, lipids, starch, and sulfur, as well as where the production of some hormones takes place. Light is one of the most important environmental factors, acting as an essential energy source for plants,...
متن کاملPlant 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 کاملThe response of Geant4 hadronic models to the study of neutrons produced in proton irradiation to the light materials
Neutron is one of the products of the interaction of high energy protons with light nuclei. Using computational Monte Carlo codes, it is possible to calculate and predict the neutron spectrum, neutron flux, and doses by simulating the system. But the use of different hadronic models in this process can influence the results of these calculations. In this research, the response of the four hadro...
