Available in PDF, EPUB and Kindle. Book excerpt: The Cereal Rusts, Volume II: Diseases, Distribution, Epidemiology, and Control is a compendium of papers that aims to control cereal rusts through principles about the nature of the disease, as well as learned strategies toward its control. These papers deal with the major cereal rust diseases such as wheat and rye stem rust, wheat leaf rust, stripe rust, oat stem rust, barley leaf rust. Control of these types of rust diseases include cultural methods, barberry eradication, crop resistance, fungicides, and ecological controls. One paper notes that cultivars, a plant variety developed through selective breeding, should be used. The key to its development with long-lasting resistance is diversity, namely, genetic diversity in resistance types, and diversity in its strategic development, including a combination of race-specific with non-race specific resistance. For example, Parlevliet has pointed out that in natural ecosystems, race-specific resistance can protect the host plant by rendering the pathogen population less aggressive. One paper also examines the use of chemicals for rust disease control in the United States. This compendium is ideally suited for the cytologists, physiologists, biochemists, geneticists, epidemiologists, taxonomists, and cereal plant pathologists.

Download or read book Disease Resistance in Plants written by J.E. Vanderplank and published by Elsevier. This book was released on 2012-12-02 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: Disease Resistance in Plants, Second Edition, looks at genetic, epidemiologic, biochemical, and biometric principles for developing new cultivars possessing genetic resistance to diseases. It examines the nature of disease resistance and resistance genes, and it highlights the importance of stabilizing selection, sugar, biotrophy, and necrotrophy to obtain the greatest possible yields. Organized into 17 chapters, this volume begins with an overview of disease resistance in plants and the ways to develop disease-resistant variants. It then discusses unspecific resistance; the resistance gene paradox; susceptibility and resistance within narrow host taxa; phenotypic variation and gene numbers in host plants; discontinuous variation and cytoplasmic inheritance; and experimental difficulties in partitioning variance. The reader is also introduced to epistasis and the structure of virulence in pathogens; the notion of physiological race; how the pathogen adapts to the host; mutation in the pathogen from avirulence to virulence; horizontal and vertical resistance to disease and its epidemiological effects; and the link between protein polymorphism and vertical resistance. In addition, the book discusses genes for susceptibility in the host versus genes for avirulence (or virulence) in the pathogen; sink-induced loss of resistance; high-sugar disease processes and biotrophy; slow rusting of cereal crops; plant resistance against endemic disease; and the accumulation of resistance genes in heterogeneous host populations. This book will be useful to plant pathologists and plant breeders.
