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.

Rinie Hofstra has been a member of the Department of Plant Physiology, University of Groningen, the Netherlands, for 24 years. The nearer we came to 31 March 1985, her 65th birthday, the more we all realized how we would miss her - not only scientifically, but also socially. She left her mark on both research and teaching, always with an open mind and willing to change. After her PhD Thesis on 'Nitrogen Metabolism in Tomato Plants' she first continued working in that field, but soon started a joint project with the Department of Plant Ecology on hemiparasites. She then became involved in carbon metabolism, which resulted in her giving a Biotrop Course on C /C metabolism in 3 4 Indonesia. Her own research group, originally working on 'Nitrogen Metabolism', soon embraced 'Energy and Nitrogen Metabolism', as the research on respiration became more and more important. In running her group she showed all sides of her person. She used to stimulate and encourage everyone around her and to integrate the various lines of research. At the same time she always had an open mind for the opinion of all members of her group. And together they regularly criticized and evaluated the various projects and decided how to continue.

It must have been some feeling of frustration invoked by the genus loci of big conferences which brought Don Dougall, Mike Fowler, and me over a cup of coffee to think of organizing a small meeting on cell culture metabol ism. The basic aim was to bring people working on "primary metabolism" and those who work on "secondary metabolism" to interact with each other, hopefully to induce some new approaches to utilize the cell culture technique more efficiently in basic research and in its practical application. The out come of this was the small symposium at SchloE Rauischholzhausen near GieEen (Germany), and the reader of this small volume of articles on topics discussed will judge to what extent this aim was realized. Although F.e. Steward was unable to attend the meeting, we were happy that he contributed a review on some important turning points of the cell culture method in the past, and at the end of the book some participants of the meeting attempted some prognosis on possible future developments, summarized by Mike Fowler. It was the wish of our publisher to organize the contributions as a summary of the major topics of research of the individual groups represented at the meeting. Due to this, some readers will certainly feel that important areas of research in the cell culture field are missing. This is regrettable, but space had to be limited to keep this volume at a reasonable price.

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.

Biological nitrogen fixation provides more than 50% of the total annual input of the essential element nitrogen to world agriculture. Thus, it is of immense agronomic importance and critical to food supplies, particularly in developing countries. This book, with chapters authored by internationally renowned experts, provides a comprehensive and detailed account of the fascinating history of the process - including the surprising discoveries of molybdenum-independent nitrogenases and superoxide-dependent nitrogenase; a review of Man's attempts to emulate the biological process - most successfully with the commercially dominant Haber-Bosch process; and the current state of the understanding art with respect to the enzymes - called nitrogenases - responsible for biological nitrogen fixation. The initial chapters use a historical approach to the biological and industrial processes, followed by an overview of assay methodologies. The next set of chapters focuses on the classical enzyme, the molybdenum nitrogenase, and details its biosynthesis, structure, composition, and mechanism of action as well as detailing both how variants of its two component proteins are constructed by recombinant DNA technology and how computational techniques are being applied. The sophisticated chemical modelling of the metal-containing clusters in the enzyme is reviewed next, followed by a description of the two molybdenum-independent nitrogenases - first, the vanadium-containing enzyme and then the iron-only nitrogenase - together with some thoughts as to why they exist! Then follows an up-to-date treatment of the clearly "non-classical" properties of the superoxide-dependent nitrogenase, which more closely resembles molybdenum-containing hydroxylases and related enzymes, like nitrate reductase, that it does the other nitrogenases. Each chapter contains an extensive list of references. This book is the self-contained first volume of a comprehensive seven-volume series. No other available work provides the up-to-date and in-depth coverage of this series and this volume. This book is intended to serve as an indispensable reference work for all scientists working in this area, including agriculture and the closely related metals-in-biology area; to assist students to enter this challenging area of research; and to provide science administrators easy access to vital relevant information.

The innovative theme of the International Treatise Series on “Advances in Plant Physiology”, Volume 12 “Physiological and Molecular Interventions for Crop Improvement under Changing Environments” has been especially edited for rational use by planners, scientists, investigators, academicians and postgraduate students. This book is an exceptional assimilation of timely, vital and inclusive twelve worthy reviews of varied significance, especially in view of the changing macro- and micro-climate influencing physiology of plants at all levels, contributed by true commitment of experienced, laudable and well-known scientists/ stalwarts all over the world. This is also strongly realized that there is with time more a need of united effort for the holistic development in the agricultural sciences, which absolutely depends on environmental situations. The threat of changing climate has imposed challenge to world scientists and their efforts in understanding reasons of yield reductions at physiological and molecular levels have been intensified. The consistent outcome are imparted with genetic engineers who have to now under the present circumstances exclusively identify, isolate and purify specific genes from DNA sequences befitting for development of tolerance mechanism in crop plants under changes of different degrees of intensity in environment. That is naturally the step wise long process having several pros and cons to arrive at any conclusion. Hence, the treatise series is the need of the hour and excellent source to disseminate meaningful distilled thoughts emerging out of extensive research which has due relevance for planning consequential basic strategic research besides direct help to the mankind. The intricacies of abiotic and biotic stresses on growth and development of plants have been understood in the last few decades. This book too is an endeavour to make aware the young workers to gain information on researches of basic and applied significance for extending consequential research of physiological and molecular approaches for crop improvement under changing environment. The manifold ideas on basic problems of the present and the future as well as resolutions, in part, have been consolidated which will be accomplished in subsequent volumes.

Grass is a very important world crop. In some countries, for example the UK, Australia and New Zealand, animal products from grassland make a greater contribution to the value of agricultural production than does any other crop. Yet research being undertaken to further· our understanding of the factors affecting the growth and productivity of grasslands has trailed in the shadow of the determined efforts made to improve our knowledge of cereals and, to a somewhat lesser extent, legumes. However, in spite of its low profile, grassland research has resulted in considerable advances in our knowledge in the last 20 years, and we feel that this book provides a timely opportunity to bring together some of this work in a review of what is primarily the ecophysiology of the temperate grass crop. Unlike other crops grown for their grain or vegatative parts, grass and grassland products are used almost entirely for the feeding of ruminant animals; the interaction of the sward and the animal thus adds an extra dimension to investigations of the productivity of grassland. No one author could adequately encompass the breadth of work covered in the book. Acknowledged experts have therefore been selected as contributors to provide an up-to-date review of their own specialized areas. Whilst multi author texts can cause problems of lack of uniformity of approach, each contributor has been made aware of the contents of the other chapters in an attempt both to provide continuity and to prevent glaring overlaps.
