UV-B Radiation: Introduction, Effects and Adaptations | Ecology

After reading this article you will learn about:- 1. Introduction to UV-B Radiation 2. Effects of UV-B Radiation 3. Adaptations. Introduction to UV-B Radiation: Since the dramatic discovery of the ozone hole over the Antarctica in 1985, being caused by the releases of CFC’s and other greenhouse gases, there is great concern about this ozone depletion and the consequences of [...]

UV-B Radiation and the Evolution of Polyphenolics | Ecology

After reading this article you will learn about the UV-B radiation and the evolution of Polyphenolics. Solar UV-B radiation is known to stimulate the en­zymes phenylalanine amonialyase (PAL) and chalcone synthase (CHS) and other branch-point en­zymes of the phenylpropanoid pathway (Fig. 17.3). PAL catalyzes the transformation of phenylalanine into transcinnamic acid, which may eventually lead to the formation of complex [...]
