Chloroplast is the organelle where the life-giving process photosynthesis takes place; it is the site where plants and algae produce food and oxygen that sustain our life. The story of how it originates from proplastids, and how it ultimately dies is beautifully portrayed by three authorities in the field: Basanti Biswal, Udaya Biswal and M. K. Raval. I consider it a great privilege and honor to have been asked to write this foreword. The book ' Chloroplast biogenesis: from proplastid to gerontoplast' goes much beyond photosynthesis. The character of the book is different from that of many currently available books because it provides an integrated approach to cover the entire life span of the organelle including its senescence and death. The books available are mostly confined to the topics relating to the 'build up' or development of chloroplast during greening. The story of organelle biogenesis without description of the events associated with its regulated dismantling during genetically programmed senescence is incomplete. A large volume of literature is available in this area of chloroplast senescence accumulated during the last 20 years. Although some of the findings in this field have been organized in the form of reviews, the data in the book are generalized and integrated with simple text and graphics. This book describes the structural features of prop las tid and its transformation to fully mature chloroplast, which is subsequently transformed into gerontoplast exhibiting senescence syndrome. The book consists of five major chapters.
The Principles of Biology sequence (BI 211, 212 and 213) introduces biology as a scientific discipline for students planning to major in biology and other science disciplines. Laboratories and classroom activities introduce techniques used to study biological processes and provide opportunities for students to develop their ability to conduct research.
This is a thorough study of photosynthetic mechanisms from cells to leaves, crown, and canopy. The authors question whether photosynthetic adaptations take place primarily at the metabolic and biochemical level or through changes in structure and form, or both. The text goes on to analyze the relative importance of genes that control metabolic and light reactions, and the structure, arrangement, and orientation of photosynthesis.
Provides a thorough overview of current research with the green alga Chlamydomonas on chloroplast and mitochondrial biogenesis and function, with an emphasis on the assembly and structure-function relationships of the constituents of the photosynthetic apparatus. Contributions emphasize the multidisciplinary nature of current research in photosynthesis, combining molecular genetics, biochemical, biophysical, and physiological approaches. The 36 articles address topics including nuclear genome organization; RNA stability and processing; splicing; translation; protein targeting in the chloroplast; photosystems; pigments; glycerolipids; the ATP synthase; and ferrodoxin and thioredoxin. Further contributions address new measurements methods for photosynthetic activity in vivo; starch biosynthesis; the responses of Chlamydomonas to various stress conditions; nitrogen assimilation; and mitochondrial genetics.

The volume is intended as an introduction to the physical principles governing the main processes that occur in photosynthesis, with emphasis on the light reactions and electron transport chain. A unique feature of the photosynthetic apparatus is the fact that the molecular structures are known in detail for essentially all of its major components. The availability of this data has allowed their functions to be probed at a very fundamental level to discover the design principles that have guided evolution. Other volumes on photosynthesis have tended to focus on single components or on a specific set of biophysical techniques, and the authors’ goal is to provide new researchers with an introduction to the overall field of photosynthesis. The book is divided into sections, each dealing with one of the main physical processes in photosynthetic energy conversion. Each section has several chapters each describing the role that a basic physical property, such as charge or spin, plays in governing the process being discussed. The chapters proceed in an orderly fashion from a quantum mechanical description of early processes on an ultrafast timescale to a classical treatment of electron transfer and catalysis on a biochemical timescale culminating in evolutionary principles on a geological timescale.
Chloroplasts are vital for life as we know it. At the leaf cell level, it is common knowledge that a chloroplast interacts with its surroundings – but this knowledge is often limited to the benefits of oxygenic photosynthesis and that chloroplasts provide reduced carbon, nitrogen and sulphur. This book presents the intricate interplay between chloroplasts and their immediate and more distant environments. The topic is explored in chapters covering aspects of evolution, the chloroplast/cytoplasm barrier, transport, division, motility and bidirectional signalling. Taken together, the contributed chapters provide an exciting insight into the complexity of how chloroplast functions are related to cellular and plant-level functions. The recent rapid advances in the presented research areas, largely made possible by the development of molecular techniques and genetic screens of an increasing number of plant model systems, make this interaction a topical issue.
It is now about 100 years since the chloroplast has been recognized as the site of photosynthesis in plant cells. The last 20 years have seen a striking increase in interest in the structure and function of the chloroplast. Hastened on by powerful new tools such as the electron microscope and the newer methods of isolation and analysis of chloroplasts, there is presently considerable experimental work on the properties of this organelle. In such a rapidly moving field and one which is reviewed systematically is various Annual Reviews, it is not possible to present a detailed critique of the prolific literature in a book of reasonable size. Rather the decision was made to sacrifice complete coverage of the field and to indicate general areas of investigation. In organization, problems here dealt with, are those concerned with the electron microscopy of chloroplast structure, development and conformation, genetic control of chloroplast development, characterization of some of the major components of the chloroplast and the biochemical properties of the chloroplast including the for mation of adenosine triphosphate and reduced pyridine nucleotide and the assim ilation of carbon dioxide into carbohydrate with subsequent conversion to second ary products. A historical outline on the general subject "Photosynthesis and the Chloroplast" has been included to place into proper perspective the rapid developments in the several areas covered in the book. I am particularly indebted to Dr. Roy E.
