The Downy Mildews Biology, Mechanisms of Resistance and Population Ecology

About this book

Knowledge of downy mildew pathogens and diseases has increased significantly in the areas of taxonomy, biology and molecular biology, mechanisms of resistance, population biology and ecology, epidemiology and chemical control. The opportunity to update comprehensively the major advances in these areas arose from the International Congress of Plant Pathology (ICPP) held in August 2008 at Torino (Italy). Contributions from this meeting are published here in 17 chapters that provide the most authoritative and recent analysis of these biotrophic plant pathogens and their interactions with plants. All contributions are either comprehensive critical reviews or original research papers, and cover the most relevant and recent topics related to these important biotrophic plant pathogens. It will be an invaluable resource to students and researchers in plant pathology, mycology, taxonomy, plant biology and crop protection. The recent Special Issue is a continuation of previous one published by Springer in 2008.
