Recent years have seen tremendous progress in unraveling the molecular basis of different plant-microbe interactions. Knowledge has accumulated on the mecha nisms of the microbial infection of plants, which can lead to either disease or resistance. The mechanisms developed by plants to interact with microbes, whether viruses, bacteria, or fungi, involve events that can lead to symbiotic association or to disease or tumor formation. Cell death caused by pathogen infection has been of great interest for many years because of its association with plant resistance. There appear to be two types of plant cell death associated with pathogen infection, a rapid hypersensitive cell death localized at the site of infection during an incompatible interaction between a resistant plant and an avirulent pathogen, and a slow, normosensitive plant cell death that spreads beyond the site of infection during some compatible interactions involving a susceptible plant and a virulent, necrogenic pathogen. Plants possess a number of defense mechanisms against infection, such as (i) production of phytoalexin, (ii) formation of hydrolases, (iii) accumulation of hydroxyproline-rich glycoprotein and lignin deposition, (iv) production of pathogen-related proteins, (v) produc tion of oligosaccharides, jasmonic acid, and various other phenolic substances, and (vi) production of toxin-metabolizing enzymes. Based on these observations, insertion of a single suitable gene in a particular plant has yielded promising results in imparting resistance against specific infection or disease. It appears that a signal received after microbe infection triggers different signal transduction pathways.

This volume contains reviews presented at the 31 st annual meeting of the Phytochemical Society of North America, held at Colorado State University in Fort Collins, Colorado on June 22-26, 1991. This symposium, entitled Phenolic Metabolism in Plants, celebrated the origin of this society as the Plant Phenolics Group of North America; the first symposium, entitled Biochemistry of Plant Phenolic Substances, was also held at Fort Collins from August 31 to September 1, 1961. A brief history of the Society is presented in Chapter 12 by Stewart Brown, one of the original founders of the Society. We dedicate this volume to Hans Grisebach, 1926-1990, Professor of Biochemistry at the Biologisches Institut II, Freiburg, Germany, where he headed for many years a laboratory responsible for major advances in the area of phenolic metabolism; this will be self evident from the numerous bibliographical references cited in the literature for papers by his Freiburg group from about 1958 until now, and subsequently by former students and colla borators. His impact on the data reviewed in this volume will testify to this.

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.

This volume is a wide-ranging critical evaluation by international experts of the state of knowledge in the whole field of biological nitrogen fixation. It includes coverage of the chemistry of N2 reduction, the biochemistry and molecular biology of the molybdenum and vanadium nitrogenases. There is review of the whole range of organisms fixing N2, including the free-living and symbiotic organisms (bacteria, cyanobacteria, actinomycetes). Detailed consideration is given to the ecology and agricultural use of the root nodule bacteria, the molecular biology and biochemistry of nodule formation and fuction. The practicability of extending symbiotic N2-fixation to other systems or to greater efficiency is examined.

The discovery of biological activity associated with flavonoid contaminants in vitamin C preparations from bell peppers and lemons by Szent-Gyorgyi and his associates opened a floodgate of research into the biological functions of this ubiquitous and diverse group of compounds. Since then, a broad range of physiological and biochemical activities were discovered in living systems including most plants and animals. With the continued discovery, isolation and identification of new natural and synthetic compounds exhibiting biological activities, entire research programs are devoted to wide ranging investigations to nearly every conceivable area, from microbial and plant interaction, growth regulation and development to physiological, genetical, medicinal actions and uses in animals. This volume is based on presentations made at a Symposium, titled Flavonoids in Cell Function, held during the 219'h National Meeting of the American Chemical Society held in San Francisco, California on March 29-30, 2000. The book is not intended to be a comprehensive treatise on flavonoid research, only a sampling of recent results. The papers cover a range of topics discussing various approaches to flavonoid study, starting at plant microbe communication through analytical methods to medicinal and systemic implications of these compounds in animal cells and systems. The organizers would like to express their thanks to Cargill Foods, Inc., Minneapolis, Minnesota and the Division of Agricultural and Food Chemistry of the American Chemical Society for financial support. A great deal of thanks is also due to the authors without whose cooperation and patience this volume would not be realized.
