Light Emission by Plants and Bacteria deals mainly with light coming from plants and bacteria as a result of various different reactions. This book emphasizes the light emission from photosynthetic organisms. The major aim of this book is to give insight on light emission studies in plant and bacteria in terms of its physiological, biophysical, and biochemical relevance. The book is divided into six parts. Part I serves as an introduction and at the same time a historical review and development of different concepts of the emission phenomena. Part II tackles the relationship of light emission to the various photosynthetic reactions. Part III discusses the concept of bioluminescence, with a focus on bacteria and dinoflagellates. Part IV is a description of the light emission from bacteriorhodopsin and rhodopsin. Part V discusses the special light emission characteristics and their relationship to specialized pigment systems found in different bacteria and plant groups. It also reviews the fluorescence properties of photosynthetic bacteria. Lastly, Part VI basically shows the practical applications of light emission from algae as well as higher plants. This book contains not only relevant information about theories and concepts, but also experiments. Thus, it is a recommended reference to researchers and students alike in the field of cell biology, microbiology, plant physiology, biochemistry, biophysics, and agriculture.

This landmark collective work introduces the physical, chemical, and biological principles underlying photosynthesis: light absorption, excitation energy transfer, and charge separation. It begins with an introduction to properties of various pigments, and the pigment proteins in plant, algae, and bacterial systems. It addresses the underlying physics of light harvesting and key spectroscopic methods, including data analysis. It discusses assembly of the natural system, its energy transfer properties, and regulatory mechanisms. It also addresses light-harvesting in artificial systems and the impact of photosynthesis on our environment. The chapter authors are amongst the field’s world recognized experts. Chapters are divided into five main parts, the first focused on pigments, their properties and biosynthesis, and the second section looking at photosynthetic proteins, including light harvesting in higher plants, algae, cyanobacteria, and green bacteria. The third part turns to energy transfer and electron transport, discussing modeling approaches, quantum aspects, photoinduced electron transfer, and redox potential modulation, followed by a section on experimental spectroscopy in light harvesting research. The concluding final section includes chapters on artificial photosynthesis, with topics such as use of cyanobacteria and algae for sustainable energy production. Robert Croce is Head of the Biophysics Group and full professor in biophysics of photosynthesis/energy at Vrije Universiteit, Amsterdam. Rienk van Grondelle is full professor at Vrije Universiteit, Amsterdam. Herbert van Amerongen is full professor of biophysics in the Department of Agrotechnology and Food Sciences at Wageningen University, where he is also director of the MicroSpectroscopy Research Facility. Ivo van Stokkum is associate professor in the Department of Physics and Astronomy, Faculty of Sciences, at Vrije Universiteit, Amsterdam.

Bioluminescence is everywhere on earth—most of all in the ocean, from angler fish in the depths to the flashing of dinoflagellates at the surface. Here, Thérèse Wilson and Woody Hastings explore the natural history, evolution, and biochemistry of the diverse array of organisms that emit light. While some bacteria, mushrooms, and invertebrates, as well as fish, are bioluminescent, other vertebrates and plants are not. The sporadic distribution and paucity of luminous forms calls for explanation, as does the fact that unrelated groups evolved completely different biochemical pathways to luminescence. The authors explore the hypothesis that many different luciferase systems arose in the early evolution of life because of their ability to remove oxygen, which was toxic to life when it first appeared on earth. As oxygen became abundant and bioluminescence was no longer adequate for oxygen removal, other antioxidant mechanisms evolved and most luminous species became extinct. Those light-emitting species that avoided extinction evolved uses with survival value for the light itself. Today’s luminous organisms use bioluminescence for defense from predators, for their own predatory purposes, or for communication in sexual courtship. Bioluminescence was earlier viewed as a fascinating feature of the living world, but one whose study seemed unlikely to contribute in any practical way. Today, bioluminescence is no longer an esoteric area of research. Applications are numerous, ranging from the rapid detection of microbial contamination in beef and water, to finding the location of cancer cells, to working out circuitry in the brain.

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.

Photosynthesis--the capture of light energy by living organisms -is a simple enough concept, but its investigation draws on the resources of disciplines from all fields of science. The aim of this text is to provide a clear, stimulating and essentially affordable coverage for undergraduate students of biology. The activity of science is debate and practical experiment; its product is a body of propositions which at any given time reflects the judgment and prejudices of those taking part. The value of a proposition is related to the conceivable alternatives, and writing it down without its context creates the false impression that science progresses by compilation of an increasing list of absolute truths. It does not; the facts and figures pres ented in the following pages have no intrinsic value unless they can be used by the reader to support an argument or point of view. In short, the reader is urged to respond 'So what?' to every item. Secondly, ideas-like other foods-should be date-stamped; science is inseparable from its history. I have set out time-charts to represent the evolution of our understanding in certain areas. I have assumed that the reader is pursuing a course with a content of biochemistry, microbiology and plant science, or has access to basic texts. I have assumed also that common methods such as spectrophotometry, chromatography and electrophoresis, as well as the techniques of mol ecular biology, will be either part of the same course or in active use nearby.

Plants as sessile organisms have evolved fascinating capacities to adapt to changes in their natural environment. Arguably, light is by far the most important and variable environmental factor. The quality, quantity, direction and duration of light is monitored by a series of photoreceptors covering spectral information from UVB to near infrared. The response of the plants to light is called photomorphogenesis and it is regulated by the concerted action of photoreceptors. The combined techniques of action spectroscopy and biochemistry allowed one of the important photoreceptors – phytochrome – to be identified in the middle of the last century. An enormous number of physiological studies published in the last century describe the properties of phytochrome and its function and also the physiology of blue and UV-B photoreceptors, unidentified at the time. This knowledge was summarized in the advanced textbook “Photomorphogenesis in Plants” (Kendrick and Kronenberg, eds., 1986, 1994). With the advent of molecular biology, genetics and new molecular, cellular techniques, our knowledge in the field of photomorphogenesis has dramatically increased over the last 15 years.

Photosynthesis, Volume 1: Energy Conversion by Plants and Bacteria tackles the conversion of light energy into the production of ATP and NADPH in both plants and bacteria. The various aspects of the energy conversion process in plants and bacteria are thoroughly discussed in this volume. The concepts and terms employed in the book are used integrally, except when a process is unique to one system. This book, which comprises of six parts, emphasizes both the biochemical and biophysical aspects of photosynthesis. It includes a review of the historical development of major concepts, an analysis of experimental data, and an exposition of subsequent findings. The first part of this book serves as the foundation of basic terms and concepts that will be used all throughout in this book. Part II deals with the structure and function, whereas Part III with the primary photochemistry. Part IV is about electron transport, while Part V focuses on photophosphorylation. The last part deals with the biosynthesis of pigments. This book will be a great reference for researchers. It will also be an introductory work for students in cell biology, physiology, biochemistry, and biophysics.
