Book Description
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.

Book Description
This volume is based on papers presented by invited speakers at a symposium entitled "Plant Nitrogen Metabolism" held in conjunction with the 28th Annual Meeting of the Phytochemical Society of North America. The meeting took place on the campus of the University of Iowa at Iowa City during June 26-30, 1988, and attracted 110 participants from 11 countries. The goal of the symposium was to trace the pathway by which nitrogen passes from soil and atmosphere into both primary and secondary nitrogenous metabolites, focusing upon areas which were felt to be most rapidly expanding. From nodulines (nodule specific proteins) and GS/GOGAT mutants to sugar mimics (polyhydroxyalkaloids) and herbicide inhibitors of amino acid metabolism, research in nitrogen metabolism has expanded into areas barely envisioned only a few years ago. Both the nitrogen specialist and the general plant biochemist will be pleased by the range of topics covered here. Following an overview in Chapter 1 of plant nitrogen metabolism, the remaining chapters are loosely organized into three groups. Chapters 2-6 deal primarily with the biochemistry and molecular biology of nitrogen assimilation and transport, Chapters 7-9 with amino acid metabolism, and Chapters 10-12 with secondary metabolites.

Book Description
Soybean plants require a large amount of nitrogen either from nitrogen fixation in nodules or nitrogen absorption from roots. It is known that nitrate, a major inorganic nitrogen compound in upland soils, represses nodule growth and nitrogen fixation. Rapid and reversible inhibition of nodule growth and nitrogen fixation activity was found in the hydroponically cultivated soybeans after changing the nutrient solution with or without nitrate. Isotope tracer analysis revealed that the major cause of this inhibition depended on the changes in the partitioning of photo-assimilate between nodules and roots and was not directly related to the transported N compounds. Transcriptome and metabolome analyses supported that nitrate strongly promotes nitrogen and carbon metabolism in the roots but represses them in the nodules. The application of ammonium, glutamine, or urea also inhibited the nodule growth and nitrogen fixation like nitrate, although the inhibition was lower than that of nitrate. The degree of inhibition was related to the decrease in carbon isotope partitioning into the nodules, rather than the import of nitrogen isotope to nodules. Urea was detected in xylem sap and all parts of soybean, and some urea might be originated from ureide degradation.

Book Description
Plant Physiology: A Treatise, Volume VIII: Nitrogen Metabolism focuses on the physiological aspects of nitrogen metabolism in plants. This book considers the descriptive biochemistry by which nitrogen compounds and their reactions are recognized; the way the feasible reactions are assembled into metabolic pathways and cycles that give meaningful purpose and direction to the course of metabolism; and the ongoing fate of nitrogen compounds in relation to ontogeny, growth, and development. This volume is organized into four chapters and begins with an introduction to developments in basic and applied biological nitrogen fixation, focusing on the agriculturally important mechanisms by which atmospheric nitrogen is converted to plant protein. The biology and biochemistry of nitrogen-fixing associations and their practical application in agriculture are discussed, along with nitrogen metabolism in the context of various actual situations in which cells divide and grow and specific plants develop, mature, and reproduce. The next chapter deals with the metabolism and turnover of proteins, citing specific proteins (the enzymes ribulosebisphosphate carboxylase and nitrate reductase and seed protein) as the type cases to illustrate the fate of special proteins through their formation and turnover. The mechanisms and biological settings of protein degradation, as distinct from breakdown during protein turnover, are also covered in detail. This book is intended for teachers, research workers, and students with specific interest in plant physiology.

Book Description
Amino Acid - New Insights and Roles in Plant and Animal provides useful information on new aspects of amino acid structure, synthesis reactions, dietary application in animals, and metabolism in plants. Section 1 includes chapters that describe the therapeutic uses, antiallergic effects, new aspects in the D-amino acid structure, historical background of desmosines, and stereoselective synthesis of ?-aminophosphonic acids. Section 2 presents the role of amino acids in plants, which includes new insights and aspects of D-amino acids, metabolism and transport in soybean, changes during energy storage compound accumulation of microalgae, and determination of amino acids from natural compounds. Section 3 describes the chapters on methodologies and requirement of dietary amino acids for Japanese quails, laying hens, and finishing pigs. The final chapter identifies potential importance of glutathione S-transferase activity for generating resistance to triclabendazole in Fasciola hepatica.
