For investigators engaged in the study of toxins generally, and host-specific toxins in particular, it is a rare treat to attend a meeting in which toxins involved in plant pathogenesis are emphasized. A gathering of this type provides opportunity to consider the discovery of new toxins, their chemical structures, genes encoding enzymes that control their biosyntheses, their sites of action and physiological effects on plants, and their roles (if any) in pathological processes. Having acknowledged the inspiration fostered by a 'toxin meeting', however, it is important to point out that the program of this symposium was generously sprinkled with 'nontoxin' talks. These contributions generated cross-disciplinary discussion and promoted new ways of thinking about relationships among factors required for plant disease development. The point can be illustrated by considering just one example. We have in the past often regarded diseases mediated by host-specific toxins and diseases involving 'gene-for-gene' relationships as representing two different classes of fungal/plant interaction. This is largely because the key molecular recognition event in so-called 'toxin' diseases leads to compatibility, whereas the corresponding event in 'gene-for-gene' diseases leads to incompatibility. Yet the race specific elicitors produced by the 'gene-for-gene' fungi Cladosporium fulvum (De Wit, Adv. Bot. Res. 21:147- 185, 1995) and Rhynchosporium secalis (Rohe et a1. , EMBO J.

This book offers a collection of information on successive steps of molecular 'dialogue' between plants and pathogens. It additionally presents data that reflects intrinsic logic of plant-parasite interactions. New findings discussed include: host and non-host resistance, specific and nonspecific elicitors, elicitors and suppressors, and plant and animal immunity. This book enables the reader to understand how to promote or prevent disease development, and allows them to systematize their own ideas of plant-pathogen interactions.* Offers a more extensive scope of the problem as compared to other books in the market* Presents data to allow consideration of host-parasite relationships in dynamics and reveals interrelations between pathogenicity and resistance factors* Discusses beneficial plant-microbe interactions and practical aspects of molecular investigations of plant-parasite relationships* Compares historical study of common and specific features of plant immunity with animal immunity

Research in the genomics of a handful of fungi has matured at an unprecedented rate allowing comprehensive review. Developments in fungal genomics should be of great significance to new strategies in fields where disciplinary crossovers of fungal genomics, genes and their regulation, expression, and engineering will have a strong impact in dealing with agriculture, foods, natural resources, life sciences, biotechnology, informatics, metabolomics, pharmaceuticals and bioactive compounds. This volume analyzes the commonly used molecular markers systems, and elaborates the development of biochemical genetics, which provides a model system that established the relationship between genes and enzymes. Current knowledge about the genomic and genetic variability of Candida albicans, the polymorphic fungus that is an opportunistic human pathogen of increasing medical importance, has been covered in detail. Current understanding of the genetics and functional genomic analysis of the most important fungal pathogens of staple food crops, rice and wheat among others is covered including chapters dealing with the genomics of economically important fungi such asMagnaporthe grisea, Aspergillus, Fusarium, Penicillium, Trichoderma, Rhizoctonia, Mycosphaerella graminicola, and entomopathogenic fungi. With several thousand recent citations, it is hoped that volume four will serve as a useful reference for knowledgeable veterans and beginners as well as those crossing disciplinary boundaries into the exciting field of biotechnology, genomics and bioinformatics of fungi.

William C. Taylor Department of Genetics University of California Berkeley, California 94720 It is evident by now that there is a great deal of interest in exploiting the new technologies to genetically engineer new forms of plants. A purpose of this meeting is to assess the possibilities. The papers that follow are concerned with the analysis of single genes or small gene families. We will read about genes found within the nucleus, plastids, and bacteria which are responsible for agri culturally important traits. Given that these genes can be isolated by recombinant DNA techniques, there are two possible strategies for plant engineering. One involves isolating a gene from a cultivated plant, changing it in a specific way and then inserting it back into the same plant where it produces an altered gene product. An example might be changing the amino acid composition of a seed pro tein so as to make the seed a more efficient food source. A second strategy is to isolate a gene from one species and transfer it to another species where it produces a desirable feature. An example might be the transfer of a gene which encodes a more efficient pho tosynthetic enzyme from a wild relative into a cultivated species. There are three technical hurdles which must be overcome for either strategy to work. The gene of interest must be physically isolated.

Microbial Transformations of Steroids: A Handbook aims to provide those who wish to use microbial transformations of steroids with a single source book starting from 1937 to the present. The handbook first offers information on the history of the microbial transformations of organic compounds, including earliest works on the study of nonsteroids and steroids; significance of discovery of anti-inflammatory action of cortisone; first hydroxylations and dehydrogenations; manufacture of natural and synthetic corticosteroids; and trends in research. The text then ponders on chemical classification of microbial transformations of steroids, as well as the role of enzymes in microbial transformations and the classes of reactions. The publication elaborates on the construction and use of the table. Topics include order of the table, nomenclature, description of the transformation leading to the product, yield, organism, and constants. The book also focuses on taxonomy and use of the table, including system of classification, specific notes on divisions of the table, and source of cultures. The handbook is a valuable source of data for readers interested in the microbial transformations of steroids.

This volume addresses the similarities and also the differences in the genomes of soil saprophytes, symbionts, and plant pathogens by using examples of fungal species to illustrate particular principles. It analyzes how the specific interactions with the hosts and the influence of the environment may have shaped genome evolution. The relevance of fungal genetic research and biotechnological applications is shown for areas such as plant pathogenesis, biomass degradation, litter decomposition, nitrogen assimilation, antibiotic production, mycoparasitism, energy, ecology, and also for soil fungi turning to human pathogens. In addition to the model organisms Neurospora and Aspergillus, the following species are covered providing a view of pathogens and mutualists: Trichoderma, Fusarium oxysporum, Cochliobolus heterostrophus, Penicillium chrysogenum, Rhizopus oryzae, Podospora anserina, and species belonging to Agaricomycetes, Archaeorhizomycetes and Magnaporthaceae. Ecology and potential applications have guided the choice of fungal genes to be studied and it will be fascinating to follow the trends of future sequencing projects.

Research on the interaction between plants and microbes continues to attract increasing attention, both within the field as well as in the scientific community at large. Many of the major scientific journals have recently reviewed various aspects of the field. Several papers dealing with plant-microbe interactions have been featured on the covers of scientific publications in the past several months, and the lay press have recently presented feature articles of this field. An additional sign of the interest in this field is that the International Society of Molecular Plant-Microbe Interactions has almost 500 members. This book is a collection of the papers that were given at the Sixth Inlernational Symposium on the Molecular Genetics of Plant-Microbe Interactions which was held in Seattle, Washington in July, 1992. Approximately 650 scientists attended and approximately 50 lectures covering the topics of Agrobacterium-plant interactions, Rhizobium-plant interactions, bacteria-plant interactions, fungal-plant interactions and new aspects of biotechnology were presented. In addition, many sessions were devoted to the plant response to the microbe. Over 400 posters were presented of which the authors of 20 were selected to give an oral presentation. These papers are included in this volume as well. The symposium also included speakers whose research interests are not directly related to plant-microbe interactions but who are at the cutting edge of research areas that impact on the theme of the symposium. These individuals kindly agreed to summarize their talks and their papers are also included.
