Recounting the compelling story of a scientific discovery that took more than a century to complete, this trail-blazing monograph focuses on methodological issues and is the first to delve into this subject. This book charts how the biochemical and biophysical mechanisms of photosynthesis were teased out by succeeding generations of scientists, and the author highlights the reconstruction of the heuristics of modelling the mechanism—analyzed at both individual and collective levels. Photosynthesis makes for an instructive example. The first tentative ideas were developed by organic chemists around 1840, while by 1960 an elaborate proposal at a molecular level, for both light and dark reactions, was established. The latter is still assumed to be basically correct today. The author makes a persuasive case for a historically informed philosophy of science, especially regarding methodology, and advocates a history of science whose narrative deploys philosophical approaches and categories. She shows how scientists’ attempts to formulate, justify, modify, confirm or criticize their models are best interpreted as series of coordinated research actions, dependent on a network of super- and subordinated epistemic goals, and guided by recurrent heuristic strategies. With dedicated chapters on key figures such as Otto Warburg, who borrowed epistemic fundamentals from other disciplines to facilitate his own work on photosynthesis, and on more general topics relating to the development of the field after Warburg, this new work is both a philosophical reflection on the nature of scientific enquiry and a detailed history of the processes behind one of science’s most important discoveries.

Bioenergetics of Photosynthesis covers the transformation of energy in biological systems, with an emphasis on photosynthesis. The biochemical and biophysical aspects are given much focus in this book. The historical development of the concepts used in this book is reviewed. This reference also analyzes experimental data and their results. This publication contains 12 chapters. The first chapter introduces the concept of photosynthesis. Then, the next chapter explores the relationship between chloroplast structure and function . Other concepts covered in this book include the primary events (energy transfer and light absorption), delayed light emission, and chlorophyll fluorescence. The mechanism of excitation energy, oxygen evolution, and chlorophyll fluorescence are also explained. Furthermore, this book discusses the electron transport pathway, primary acts of energy conservation in chloroplast membranes, and molecular organization of chlorophyll. Finally, it describes the relationship of the structure of chloroplast membrane to energy coupling and ion transport. This book will be a good resource for students and researchers alike, especially in the fields of cell biology, plant physiology, biochemistry, and biophysics.

This book reports the proceedings of a meeting held in the 'Limburgs Universitair Centrum' , Diepenbeek, Belgium, August 26 to 30, 1974. In convening this meet ing, my aim was to bring together a small number of specialists working on photosynthesis of course but also always keeping in mind that plants are in fluenced by their environment (temperature, light quality and intensity, air com position, daylength . . . . . ) and can differently react according to their stage of deve lopment. In general, all these specialists work on whole plants cultivated in well known conditions (they are not 'market spinach specialists') but, when necessary, give up the idea of measuring photochemical activities in isolated they don't chloroplasts, enzyme kinetics . . . etc. It is noticeable that about 50% of them are working in laboratories directly involved with applied research in agriculture or forestry. The format of the meeting was intentionally kept small but it allowed generous time for discussion; thanks are due to Drs. O. BJÖRKMAN, J. W. BRADBEER, M. M. LUDLOW and C. B. OSMOND for taking the chairs during these discussions. In such a small meeting, the choice of invited scientists was really a personnal one and thus reflected my own fields of interest. When planning the conference, I was continually divided between the wish for inviting other interesting people and the necessity of keeping time free for discussions.

"Life Is Bottled Sunshine" [Wynwood Reade, Martyrdom of Man, 1924]. This inspired phrase is a four-word summary of the significance of photosynthesis for life on earth. The study of photosynthesis has attracted the attention of a legion of biologists, biochemists, chemists and physicists for over 200 years. Discoveries in Photosynthesis presents a sweeping overview of the history of photosynthesis investigations, and detailed accounts of research progress in all aspects of the most complex bioenergetic process in living organisms. Conceived of as a way of summarizing the history of research advances in photosynthesis as of millennium 2000, the book evolved into a majestic and encyclopedic saga involving all of the basic sciences. The book contains 111 papers, authored by 132 scientists from 19 countries. It includes overviews; timelines; tributes; minireviews on excitation energy transfer, reaction centers, oxygen evolution, light-harvesting and pigment-protein complexes, electron transport and ATP synthesis, techniques and applications, biogenesis and membrane architecture, reductive and assimilatory processes, transport, regulation and adaptation, Genetics, and Evolution; laboratories and national perspectives; and retrospectives that end in a list of photosynthesis symposia, books and conferences. Informal and formal photographs of scientists make it a wonderful book to have. This book is meant not only for the researchers and graduate students, but also for advanced undergraduates in Plant Biology, Microbiology, Cell Biology, Biochemistry, Biophysics and History of Science.
