Recent Advances in Phytochemistry, Volume 5: Structural and Functional Aspects of Phytochemistry covers the proceedings of the 10th Symposium of the Phytochemical Society of North America held in Beltsville College Park, Maryland on October 6-9, 1970. The book discusses the energy conversion in both photooxidation and photophosphorylation reactions of photosynthesis; and advances in phytochrome studies, including the physiological and biochemical characterization of the pigment, the mechanism of action, and the regulation of phytochrome-mediated processes. The text also describes the structure, function, and photocontrolled synthesis of betalains; the chemistry of flavylium salts; and the histochemistry of plants in health and disease. The enzyme reaction to wound injury and parasites, and the evolution of the mechanisms of disease resistance are also considered. The book further tackles herbicide metabolism in plants; the chemistry of tea and tobacco; and the alkaloid biosynthesis of tobacco plants. Botanists, entomologists, and people involved in the study of plant chemistry will find the book invaluable.
