Photobiology is an important area of biological research since a very large number of living processes are either dependent on or governed by light that we receive from the Sun. Among various subjects, photosynthesis is one of the most important, and thus a popular topic in both molecular and organismic biology, and one which has made a considerable impact throughout the world since almost all life on Earth depends upon it as a source of food, fuel and oxygen. However, for growth of plants, light is equally essential, and research on photomorphogenesis has revealed exciting new developments with the application of newer molecular biological approaches. The present book brings together and integrates various aspects of photosynthesis, biology of pigments, light regulation of chloroplast development, nuclear and chloroplast gene expression, light signal transduction, other photomorphogenetic processes and some photoecological aspects under one cover. The chapters cover biochemical and molecular discussions of most of the above topics in a comprehensive manner and include a wide range of `hot topics' that are currently under investigation in the field of photobiology of cyanobacteria, algae and plants. The authors of this book are selected international authorities in their fields from USA, Europe, Australia and Asia. The book is designed primarily to be used as a text book by graduates and post-graduates. It is, however, also intended to be a resource book for new researchers in plant photobiology. Several introductory chapters are designed as suitable reading for undergraduate courses in integrative and molecular biology, biochemistry and biophysics.

Photobiology - the science of light and life - begins with basic principles and the physics of light and continues with general photobiological research methods, such as generation of light, measurement of light, and action spectroscopy. In an interdisciplinary way, it then treats how organisms tune their pigments and structures to the wavelength components of light, and how light is registered by organisms. Then follow various examples of photobiological phenomena: the design of the compound eye in relation to the properties of light, phototoxicity, photobiology of the human skin and of vitamin D, photomorphogenesis, photoperiodism, the setting of the biological clock by light, and bioluminescence. A final chapter is devoted to teaching experiments and demonstrations in photobiology. This book encompasses topics from a diverse array of traditional disciplines: physics, biochemistry, medicine, zoology, botany, microbiology, etc., and makes different aspects of photobiology accessible to experts in all these areas as well as to the novice.

Photophysiology, Volume I: General Principles: Action of Light on Plants focuses on the fundamental mechanisms by which non-ionizing radiations affect the living cell at the molecular level when such analysis is possible. The selection first offers information on the development of photochemistry, including photosynthesis, photoaxis, vision, phototropism, diurnal rhythms and visible light, and medical uses of ultraviolet light. The text then takes a look at the principles of photochemistry and photochemical methods and electron spin resonance and its application to photophysiology. The publication examines the photochemical action of light on macromolecules, absorption spectra, spectrophotometry, and action spectra, and photochemical reactions of photosynthesis. Discussions focus on photosynthetic phosphorylation, measurement and interpretation of action spectra, instrumentation for absorption spectra, and inactivation of viruses by visible and ultraviolet light. The selection is a valuable source of information for readers interested in photophysiology.

Concepts in Radiation Cell Biology summarizes current concepts related to the effects of radiation on cell biology, with emphasis on the underlying macromolecular basis for cellular changes in irradiated cells. It explores the effects of non-ionizing radiation, such as ultraviolet and visible light; the use of laser light in cellular studies; and the biological effects of ionizing radiation on cells. Results of ultraviolet studies implicating DNA as the main target macromolecule responsible for radiation injury, such as division delays, lethality, and delayed DNA replication, are presented. Divided into eight chapters, this volume begins with an overview of ultraviolet irradiation of DNA as well as the physical and biological properties of irradiated DNA. It then discusses methods used in the photoinactivation of viruses; the effects of ultraviolet radiation on bacteria; radiation-induced biochemical changes in protozoa; and techniques for the analysis of radiation-induced mitotic delay in synchronously dividing sea urchin eggs. The book also covers the effects of radiation on mammalian cells; the effects of ionizing radiation on higher plants; and the photodynamic effects of laser light on cells. This book is a valuable resource for cell biologists, as well as students and investigators who are seeking the necessary information for further experimentation in radiation cell biology.

The first edition of The Science of Photobiology was published in 1977, and was the first textbook to cover all of the major areas of photobiology. The science of photobiology is currently divided into 14 subspecialty areas by the American Society for Photobiology. In this edition, however, the topics of phototechnology and spectroscopy have been com bined in a new chapter entitled "Photophysics." The other subspecialty areas remain the same, i.e., Photochemistry, Photosensitization, UV Radiation Effects, Environmental Photobiology, Photomedicine, Circadian Rhythms, Extraretinal Photoreception, Vision, Photomorphogenesis, Photomovement, Photosynthesis, and Bioluminescence. This book has been written as a textbook to introduce the science of photobiology to advanced undergraduate and graduate students. The chapters are written to provide a broad overview of each topic. They are designed to contain the amount of information that might be presented in a one-to two-hour general lecture. The references are not meant to be exhaustive, but key references are included to give students an entry into the literature. Frequently a more recent reference that reviews the literature will be cited rather than the first paper by the author making the original discovery. The chapters are not meant to be a repository of facts for research workers in the field, but rather are concerned with demon strating the importance of each specialty area of photobiology, and documenting its relevance to current and/or future problems of man.

The goals of the science of photobiology can be divided into four categories: to develop (I) ways to optimize the beneficial effects of light on man and his environment, (2) methods to protect organisms, including man, from the detrimental effects of light, (3) photochemical tools for use in studies of life processes, and (4) photochemical therapies in medicine. To achieve these goals will require the knowledgeable collaboration of biologists, chemists, engineers, mathematicians, physicians, and physicists; because photobiology is a truly multidisciplinary science. While a multidis ciplinary science is more intellectually demanding, it also has a greater potential for unexpected breakthroughs that can occur when data from several areas of science are integrated into new concepts for theoretical or practical use. Photochemical and Photobiological Reviews continues to provide in depth coverage of the many specialty areas of photobiology. It is hoped that these reviews will provide an important service to the younger scientists in the field and to senior scientists in related fields, because they provide a ready access to the recent literature in the field, and more importantly, they frequently offer a critical evaluation of the direction that the field is taking, or suggest a redirection when appropriate. Since it is important that this review series remain responsive to the needs of photochemists and photobiologists, the Editor would value com ments and suggestions from its readers.

Photobiology is the scientific study of the interactions of light and living organisms. The last decades have witnessed great strides in understanding the biological effects of light from the molecular all the way up to the whole organism level. Much of the boost for advancing the science of photobiology came from the dramatic increase over this period in the incidence of melanoma and other sun-related skin diseases. In this book, current knowledge about the risks of ultraviolet radiation (UVR) on infant skin are summarised, including epidemiologic evidence regarding sun exposure in this age group. This book also explores and discusses the complex cascade of modifications induced within proteins through exposure to irradiation. Exciting new approaches to the characterisation, location, tracking, and ultimately control of photoxidation within proteins are discussed as well. Moreover, the prevention for phototoxic effect is one of the important themes of photobiology. The chemopreventive action of novel organic and inorganic materials on photosensitised biomolecules damage is described in this book. Other chapters provide insights into the death and protective responses of cells treated by photodynamic therapy (PDT) as well as the relationships among gene expressions, examine the effects of natural ultraviolet radiation at zooplankton populations and communities in inland water ecosystems, and the application of folates and their role for skin homeostasis.
