Emphasis in this second volume of Advances in Downy Mildew Research is on the biology of compatible interactions, forecasting and epidemiology, host specialisation, genetic variability amongst pathogen populations, novel methods for detection and systematics, and induced resistance. Two chapters focus on the related oomycete Albugo candida, which shares many pathogenic characteristics with the downy mildews and provides a valuable comparative pathosystem. Contributions on specific downy mildews include Bremia lactucae, Peronospora destructor, Peronospora sparsa, Peronospora viciae, Plasmopara halstedii, Plasmopara viticola, Pseudoperonospora cubensis and Sclerospora graminicola.

Knowledge of downy mildew pathogens and diseases has increased significantly in taxonomy, phylogeny, genetics, molecular biology, host-parasite interactions, ecology, epidemiology and control. The opportunity to update comprehensively the major advances in these areas was created by the 2nd International Symposium on Downy Mildews held in July 2007 at Olomouc (Czech Republic). Keynote contributions from this meeting are published here in 14 chapters that provide the most authoritative and recent analysis of these biotrophic plant pathogens and their interactions with plants. It will be an invaluable resource to students and researchers in plant pathology, mycology, taxonomy, plant biology and crop protection.
P. T. N. SPENCER-PHILLIPS Co-ordinator, Downy Mildew Working Group of the International Society for Plant Pathology University of the West of England, Coldharbour Lane, Bristol BS16 1QY, UK Email: peter.spencer-phillips@uwe.ac.uk It is a very great privilege to write the preface to the first specialist book on downy mildews since the major work edited by D. M. Spencer in 1981. The idea for the present publication arose from the Downy Mildew Workshop at the International Congress of Plant Pathology (ICPP) held in Edinburgh in August 1998. Our intention was to invite reviews on selected aspects of downy mildew biology from international authorities, and link these to a series of related short contributions reporting new data. No attempt has been made to cover the breadth of downy mildew research, but we hope that further topics will be included in future volumes, so that this becomes the first of a series following the five year ICPP cycle.
Over recent years, progress in micropropagation has not been as rapid as many expected and, even now, relatively few crops are produced commercially. One reason for this is that the biology of material growing in vitro has been insufficiently understood for modifications to standard methods to be made based on sound physiological principles. However, during the past decade, tissue culture companies and others have invested considerable effort to reduce the empirical nature of the production process. The idea of the conference `Physiology, Growth and Development of Plants and Cells in Culture' (Lancaster, 1992) was to introduce specialists in different areas of plant physiology to micropropag...
This book focuses on the ecology of the microbiology of the surfaces of above-ground, aerial portion of vascular plants (including stem, leaves, fruits and flowers), collectively known as the phylloplane. It is divided into 6 sections, highlighting both the value of this highly diverse habitat to research in microbiology and the importance of this research to plant health and ecosystem functions. Section I concerns the biodiversity and population genetics of phyllosphere communities. Section II concerns the spatial distribution and biofilm structures of microbes on the phylloplane. Section III concerns biological control and pathogenicity. Section IV describes gene expression and phyllosphere genomics. Section V focuses on leaf colonization and dispersal. Section VI deals with aerobiology and plant surface microbiology.
Articles in this volume analyze rapidly evolving approaches, many at the cusp of development, to research plant defense mechanisms, pathogen variability, and epidemiology. Jones and Jones focus on emerging patterns that key resistance genes encode or require leucine-rich repeat proteins. Holub and Beynon analyze associating host resistance specificity with a locus and whether a phenotype is due to single or multiple genes. Ashby combines biochemical, molecular, and classical plant pathology to analyze interactions and provide leads to novel control strategies. Heath and Skalamera question why fungal biotrophs form intracellular structures, the significance of ensuing cellular rearrangements ...
Fungal-Plant Interactions is a synthesis of fungal physiology, plant pathology and biology for undergraduates and researchers. Interactions between higher plants and fungi at the cellular and biochemical level are covered together with their ecological importance and theories as to their evolution.
This book develops a new interpretation of Aristotle's Metaphysics. By exploring the significance of the long ignored distinction between being with regard to categories and being with regard to potentiality and actuality, the author presents that Aristotle's science of being has two distinct aspects: an investigation of the basic constituents of reality in terms of categories, predication, and definition, and an investigation which deals with change, process, and order of the world.
All aerial plant surfaces, including leaves, stems and flowers are inhabited by diverse assemblages of microorganisms, including filamentous fungi, yeasts, bacteria, and bacteriophages. These organisms have profound effects on plant health and thus impact on ecosystem and agricultural functions. This book is based on proceedings from the 8th International Symposium on the mircobiology of aerial plant surfaces, held in Oxford 2005. This is a five yearly conference which brings together international scientists and provides a unique opportunity to discuss developments in this field.
