There are currently intense efforts devoted to understand plant respiration (from genes toecosystems) and its regulatory mechanisms; this is because respiratory CO2 productionrepresents a substantial carbon loss in crops and in natural ecosystems. Thus, in addition tomanipulating photosynthesis to increase plant biomass production, minimization ofrespiratory loss should be considered in plant science and engineering. However, respiratorymetabolic pathways are at the heart of energy and carbon skeleton production and therefore, itis an essential component of carbon metabolism sustaining key processes such asphotosynthesis. The overall goal of this book is to provide an insight in such interactions aswell as an up-to-date view on respiratory metabolism, taking advantage of recent advancesand concepts, from fluxomics to natural isotopic signal of plant CO2 efflux. It is thus a nonoverlapping,complement to Volume 18 in this series (Plant Respiration From Cell toEcosystem) which mostly deals with mitochondrial electron fluxes and plant-scale respiratorylosses.

Respiration in plants, as in all living organisms, is essential to provide metabolic energy and carbon skeletons for growth and maintenance. As such, respiration is an essential component of a plant’s carbon budget. Depending on species and environmental conditions, it consumes 25-75% of all the carbohydrates produced in photosynthesis – even more at extremely slow growth rates. Respiration in plants can also proceed in a manner that produces neither metabolic energy nor carbon skeletons, but heat. This type of respiration involves the cyanide-resistant, alternative oxidase; it is unique to plants, and resides in the mitochondria. The activity of this alternative pathway can be measured based on a difference in fractionation of oxygen isotopes between the cytochrome and the alternative oxidase. Heat production is important in some flowers to attract pollinators; however, the alternative oxidase also plays a major role in leaves and roots of most plants. A common thread throughout this volume is to link respiration, including alternative oxidase activity, to plant functioning in different environments.

Respiration is a large and important component of the carbon economy of crops. There are already several good books dealing with the biochemistry and physiol ogy of plant respiration, but there are none I know of that are devoted to the rela tionship between respiration and crop productivity, although this relationship is more and more frequently being studied with both experiment and simulation. Crop physiology books do cover respiration, of course, but the treatment is limited. The purpose of the present book is to fill this void in the literature. The approach taken here is to use the popular two-component functional model whereby respiration is divided between growth and maintenance components. Mter thoroughly reviewing the literature, I came to the conclusion that at present this is the most useful means of considering respiration as a quantitative compo nent of a crop's carbon economy. This functional distinction is used as the frame work for describing respiration and assessing its role in crop productivity. Discussions and critiques of the biochemistry and physiology of respiration serve primarily as a means of more fully understanding and describing the functional approach to studying crop respiration. It is assumed that the reader of this book is familiar with the fundamentals of plant physiology and biochemistry. The research worker in crop physiology should find this an up-to-date summary of crop respiration and the functional model of respiration. This book is not, however, a simple review of existing data.

Mitochondria are sometimes called the powerhouses of eukaryotic cells, because mitochondria are the site of ATP synthesis in the cell. ATP is the universal energy currency, it provides the power that runs all other life processes. Humans need oxygen to survive because of ATP synthesis in mitochondria. The sugars from our diet are converted to carbon dioxide in mitochondria in a process that requires oxygen. Just like a fire needs oxygen to burn, our mitochondria need oxygen to make ATP. From textbooks and popular literature one can easily get the impression that all mitochondria require oxygen. But that is not the case. There are many groups of organismsm known that make ATP in mitochondria without the help of oxygen. They have preserved biochemical relicts from the early evolution of eukaryotic cells, which took place during times in Earth history when there was hardly any oxygen avaiable, certainly not enough to breathe. How the anaerobic forms of mitochondria work, in which organisms they occur, and how the eukaryotic anaerobes that possess them fit into the larger picture of rising atmospheric oxygen during Earth history are the topic of this book.

Photosynthesis, Photorespiration, and Plant Productivity provides a basis for understanding the main factors concerned with regulating plant productivity in plant communities. The book describes photosynthesis and other processes that affect the productivity of plants from the standpoint of enzyme chemistry, chloroplasts, leaf cells, and single leaves. Comprised of nine chapters, the book covers the biochemical and photochemical aspects of photosynthesis; respiration associated with photosynthetic tissues; and photosynthesis and plant productivity in single leaves and in stands. It provides illustrated and diagrammatic discussion and presents the concepts in outlined form to help readers understand the concepts efficiently. Moreover, this book explores the rates of enzymatic reactions and the detailed structure and function of chloroplasts and other organelles and their variability. It explains the mechanism of photosynthetic electron transport and phosphorylation and the importance of diffusive resistances to carbon dioxide assimilation, especially the role of stomata. It also discusses the importance of dark respiration in diminishing productivity; the differences in net photosynthesis that occur between many species and varieties; and the influence of climate to photosynthetic reactions. The book is an excellent reference for teachers, as well as undergraduate and graduate students in biology, plant physiology, and agriculture. Research professionals working on the disciplines of plant production and food supply will also find this book invaluable.

Photosynthesis in silico: Understanding Complexity from Molecules to Ecosystems is a unique book that aims to show an integrated approach to the understanding of photosynthesis processes. In this volume - using mathematical modeling - processes are described from the biophysics of the interaction of light with pigment systems to the mutual interaction of individual plants and other organisms in canopies and large ecosystems, up to the global ecosystem issues. Chapters are written by 44 international authorities from 15 countries. Mathematics is a powerful tool for quantitative analysis. Properly programmed, contemporary computers are able to mimic complicated processes in living cells, leaves, canopies and ecosystems. These simulations - mathematical models - help us predict the photosynthetic responses of modeled systems under various combinations of environmental conditions, potentially occurring in nature, e.g., the responses of plant canopies to globally increasing temperature and atmospheric CO2 concentration. Tremendous analytical power is needed to understand nature's infinite complexity at every level.

This book summarizes the physiological effects of bicarbonate in plants and systematically introduces readers to a bidirectional isotope labeling tracer technique used to quantify the contribution of root-derived bicarbonate to total photosynthetic inorganic carbon assimilation in plants. This method helps to shed light on the role of dissolved inorganic carbon from the soil in overall photosynthesis, an aspect that has been underestimated or neglected entirely in the past. The book quantifies the capacity for root-derived bicarbonate assimilation in certain plant species and illustrates the coupling relationship between karstification and photosynthesis. Further, it demonstrates that root-derived bicarbonate utilization is as important as stomatal-derived inorganic carbon assimilation in biological evolution and plant adaptation to the environment. Using numerous models, it also illustrates carbon isotopic mixtures in complex inorganic carbon utilization and supplements the results with numerical calculations presented as tables and figures. In short, the book offers a strikingly new perspective on photosynthesis.
