Insect Juvenile Hormone—Chemistry and Action

Volume seven of this distinguished series includes reviews of the following topics in photobiology and photochemistry: Electron spin resonance in photosynthetic systems, by E. C. Weaver and H. E. Weaver; Photochrome, a photochromic sensor, by W. Shropshire; Photosynthetic nitrogen fixation by blue-green algae, by M. B. Allen; The role of light in nitrate metabolism in higher plants, by L. Beevers and R. H. Hageman; Mode of photosensitizing action of furocoumarins, by L. Musajo and G. Rodighiero; Photosensitivity in porphyria, by W. J. Runge; Ultraviolet action and photoreactivation in algae, by P. HalIdal and 0. Taube; Chromosome aberrations induced by ultraviolet radiation, by S. Wolff; Photochemistry of nucleic acids and their constitutents, by A. J. Varghese; and Enzymatic and nonenzymatic bioluminescence, by F. H. Johnson and 0. Shimomura. The topics selected for this volume continue to further the balance and extend the excellent coverage of the photobiology and photochemistry of physiological processes. The reviews are written in a clear and concise form with the major advances in each area being stressed. The major advances are presesented and discussed in adequate relation to background material and this, together with current bibliographical citation, allows persons with a cursory acquaintance with the subject to understand and gain a usable knowledge of the topics presented. This volume, as the others in the series, will be of great value to the researcher, teacher, and advanced student in photobiology.
