Jointly published with INRA, Paris. This book covers all aspects of the transfer of nitrogen from the soil and air to a final resting place in the seed protein of a crop plant. It describes the physiological and molecular mechanisms of ammonium and nitrate transport and assimilation, including symbiotic nitrogen fixation by the Rhizobiacea. Amino acid metabolism and nitrogen traffic during plant growth and development and details of protein biosynthesis in the seeds are also extensively covered. Finally, the effects of the application of nitrogen fertilisers on plant growth, crop yield and the environment are discussed. Written by international experts in their field, Plant Nitrogen is essential reading for all plant biochemists, biotechnologists, molecular biologists and physiologists as well as plant breeders, agricultural engineers, agronomists and phytochemists.

Advances in Plant Nitrogen Metabolism is a thoughtful, provocative, and up-to-date volume that presents important physiological, biochemical, and molecular perspectives of the nitrogen metabolism in plants and regulatory networks underlying it. The book is an attempt to team up with global leading research experts working in the field of plant nitrogen metabolism to compile an up-to-date and wide-ranging volume. The main purpose of this book is to present information on the most recent developments including the different modern approaches and methodologies that are being currently employed in the field of plant nitrogen metabolism. We trust that this comprehensive volume will familiarize readers with the detailed mechanisms of nitrogen metabolism and its regulation and the current trends in this field of study. The book offers comprehensive coverage of the most essential topics, including: Role of nitrogen and its assimilation in plants Recycling and remobilization of nitrogen during senescence Role of phytohormones in nitrogen metabolism Biological nitrogen fixation Nitrogen biofertilizers: role in sustainable agriculture Effect of stress on plant nitrogen metabolism Reactive nitrogen species (RNS) in plants Nitrogen toxicity in plants, symptoms, and safeguards Nitrogen metabolism enzymes: structure, role, and regulation Regulatory RNAs and their role in nitrogen metabolism of diazotrophs As a pivotal contribution to the field, this volume is an invaluable and up-to-date foundation for plant physiologists, plant biochemists, geneticists, molecular biologists, agronomists, environmental researchers, and students of plant science. The book can also be used for the coursework of research and master's students.

This book discusses the association that exists between plants and their most important dietary component, nitrogen. The author combines ecological, physiological and biochemical approaches to provide the reader with an overall view of nitrogen in the biosphere and a specific view of nitrogen processing in plants. The processes which make up the nitrogen cycle, including mineralization, immobilization by microbes and nitrification, are discussed and the losses and gains of combined nitrogen from and to the cycle. The part which plants play in this cycling, by their processing of inorganic nitrogen into compounds which are required by plants and animals alike, and the chemistry and production of those compounds, is also covered. Transport of nitrogen compounds within the plant, and the fate of these compounds, is discussed. The final chapter considers the part which humans play in the cycling of nitrogen, with special reference to the nitrogen fertilizers used in agriculture.

Mineral Nitrogen in the Plant-Soil System provides integrated accounts of the transformations and fate of mineral nitrogen in the plant-soil system. This book emphasizes the understanding of various processes and the factors that affect these processes. It also focuses on the role of biological nitrogen fixation in nitrogen cycling in natural and agricultural systems. The book is divided into seven major chapters and each chapter is further subdivided into various subtopics. The first chapter introduces and outlines the origin, distribution, and cycling of nitrogen in natural and agricultural terrestrial ecosystems. Chapter 2 focuses on the processes of decomposition and mineralization-immobilization turnover. The processes of nitrification are discussed in detail in Chapter 3. The following four chapters discuss topics of retention and movement of nitrogen in soils; gaseous losses of nitrogen; uptake and assimilation of mineral nitrogen by plants; and lastly, the use of nitrogen in agronomic practice. The book will be invaluable to graduate students and researchers in the field of agriculture. This will also cater other parties interested, such as agronomists, soil scientists, plant physiologists, horticulturists, and foresters.

During the past three decades there has been a large amount of research on biological nitrogen fixation, in part stimulated by increasing world prices of nitrogen-containing fertilizers and environmental concerns. In the last several years, research on plant--microbe interactions, and symbiotic and asymbiotic nitrogen fixation has become truly interdisciplinary in nature, stimulated to some degree by the use of modern genetic techniques. These methodologies have allowed us to make detailed analyses of plant and bacterial genes involved in symbiotic processes and to follow the growth and persistence of the root-nodule bacteria and free-living nitrogen-fixing bacteria in soils. Through the efforts of a large number of researchers we now have a better understanding of the ecology of rhizobia, environmental parameters affecting the infection and nodulation process, the nature of specificity, the biochemistry of host plants and microsymbionts, and chemical signalling between symbiotic partners. This volume gives a summary of current research efforts and knowledge in the field of biological nitrogen fixation. Since the research field is diverse in nature, this book presents a collection of papers in the major research area of physiology and metabolism, genetics, evolution, taxonomy, ecology, and international programs.

Nitrogen is an essential element for plant growth and development and a key agricultural input-but in excess it can lead to a host of problems for human and ecological health. Across the globe, distribution of fertilizer nitrogen is very uneven, with some areas subject to nitrogen pollution and others suffering from reduced soil fertility, diminished crop production, and other consequences of inadequate supply. Agriculture and the Nitrogen Cycle provides a global assessment of the role of nitrogen fertilizer in the nitrogen cycle. The focus of the book is regional, emphasizing the need to maintain food and fiber production while minimizing environmental impacts where fertilizer is abundant, and the need to enhance fertilizer utilization in systems where nitrogen is limited. The book is derived from a workshop held by the Scientific Committee on Problems of the Environment (SCOPE) in Kampala, Uganda, that brought together the world's leading scientists to examine and discuss the nitrogen cycle and related problems. It contains an overview chapter that summarizes the group's findings, four chapters on cross-cutting issues, and thirteen background chapters. The book offers a unique synthesis and provides an up-to-date, broad perspective on the issues of nitrogen fertilizer in food production and the interaction of nitrogen and the environment.
