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 [...]
After reading this article you will learn about the effects of global warming on plants. Some of the greenhouse gases like tropospheric CO2 have direct effects on vegetation while CFCs indirectly affect plant growth by enhancing the flux of UV-B radiation. Others, such as CH4 and N2O, appear to have no direct effects on plants, although they form significant microbial [...]
