UV–B Radiation – From Environmental Stressor to Regulator of Plant Growth

Ultraviolet B (UV-B) is electromagnetic radiation coming from the sun, with a medium wave which is mostly absorbed by the ozone layer. The biological effects of UV-B are greater than simple heating effects, and many practical applications of UV-B radiation derive from its interactions with organic molecules.Considered particularly harmful to the environment and living things, what have scientific studies actually shown? UV-B Radiation: From Environmental Stressor to Regulator of Plant Growth presents a comprehensive overview of the origins, current state, and future horizons of scientific research on Ultraviolet B radiation and its perception in plants. Chapters explore all facets of UV-B research, including the basics of how UV-B s shorter wavelength radiation from the sun reaches the Earth s surface, along with its impact on the environment s biotic components and on human biological systems. Chapters also address the dramatic shift in UV-B research in recent years reflecting emerging technologies; showing how historic research which focused exclusively on the harmful environmental effects of UV-B radiation has now given way to studies on potential benefits to humans.Topics include: UV-B and its climatology UV-B and terrestrial ecosystems Plant responses to UV-B stress UB- B avoidance mechanisms UV-B and production of secondary metabolites Discovery of UVR8 Timely and important, UV-B Radiation: From Environmental Stressor to Regulator of Plant Growth is an invaluable resource for environmentalists, researchers and students, into the state-of-the-art research being done on exposure to UV-B radiation.
