Book Description
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.

Book Description
This book describes how genomics has revolutionized our understanding of agriculturally important plant-associated fungi. It illustrates some fundamental discoveries about these eukaryotic microbes with regard to the overall structure of their genomes, their lifestyles and the molecular mechanisms that form the basis of their interactions with plants. Genomics has provided new insights into fungal lifestyles and led to practical advances in plant breeding and crop protection, such as predictions about the spread and evolution of new pathogens. This volume focuses on fungi that are important cereal and other monocot plant pathogens and includes: Pyrenophora tritici-repentis, Cochliobolus sp., Colletotrichum sp., Fusarium graminearum, Mycosphaerella graminicola and Mycosphaerella fijiensis, Magnaporthe oryzae, Blumeria graminis and Puccinia graminis.

Book Description
Disease resistance is one of the major factors that can be improved to sustain yield potential in cultivated crops. This book looks at disease resistance in wheat, concentrating on all the economically important diseases -- their economic impact and geographical spread, breeding for resistance, pathogen variability, resistance mechanisms and recent advances made on resistance genes. Newer strategies for identifying resistance genes and identify resistance mechanisms are discussed, including cloning, gene transfer and the use of genetically modified plants.

Book Description
Molecular Aspects of Plant Beneficial Microbes in Agriculture explores their diverse interactions, including the pathogenic and symbiotic relationship which leads to either a decrease or increase in crop productivity. Focusing on these environmentally-friendly approaches, the book explores their potential in changing climatic conditions. It presents the exploration and regulation of beneficial microbes in offering sustainable and alternative solutions to the use of chemicals in agriculture. The beneficial microbes presented here are capable of contributing to nutrient balance, growth regulators, suppressing pathogens, orchestrating immune response and improving crop performance. The book also offers insights into the advancements in DNA technology and bioinformatic approaches which have provided in-depth knowledge about the molecular arsenal involved in mineral uptake, nitrogen fixation, growth promotion and biocontrol attributes.

Book Description
Plant Pathology explores the topic of plant pathology and aligns classic studies and knowledge in the topic with the current state of research, in an accessible format. The text is supported by summary tables of key information and, where appropriate, schematic diagrams to reinforce difficult concepts such as the process of disease infection, cell-to-cell recognition, and plant breeding mechanisms used to develop resistant cultivars. The compendium of diseases focuses on important and major economic disease organisms from a number of crop and ornamental plants, including a dedicated section on fruit crops. The compendium is supported by original photographs, photomicrographs and electron micrographs of key pathogens and the development of structures such as the haustoria and the hypha, and show processes of cellular degradation. The section on applied disease management contains short case studies highlighting key disease organisms affecting the crops of a range of growers, illustrating the environment, disease symptoms and control strategies these growers are currently using to mitigate loss of production.

Book Description
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.
