Book Synopsis Disease Resistance in Plants by : J.E. Vanderplank
Download or read book Disease Resistance in Plants written by J.E. Vanderplank. This book was released on 2012-12-02. 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.

Book Synopsis Disease Resistance in Crop Plants by : Shabir Hussain Wani
Download or read book Disease Resistance in Crop Plants written by Shabir Hussain Wani. This book was released on 2019-07-24. Available in PDF, EPUB and Kindle. Book excerpt: Human population is escalating at an enormous pace and is estimated to reach 9.7 billion by 2050. As a result, there will be an increase in demand for agricultural production by 60–110% between the years 2005 and 2050 at the global level; the number will be even more drastic in the developing world. Pathogens, animals, and weeds are altogether responsible for between 20 to 40 % of global agricultural productivity decrease. As such, managing disease development in plants continues to be a major strategy to ensure adequate food supply for the world. Accordingly, both the public and private sectors are moving to harness the tools and paradigms that promise resistance against pests and diseases. While the next generation of disease resistance research is progressing, maximum disease resistance traits are expected to be polygenic in nature and controlled by selective genes positioned at putative quantitative trait loci (QTLs). It has also been realized that sources of resistance are generally found in wild relatives or cultivars of lesser agronomic significance. However, introgression of disease resistance traits into commercial crop varieties typically involves many generations of backcrossing to transmit a promising genotype. Molecular marker-assisted breeding (MAB) has been found to facilitate the pre-selection of traits even prior to their expression. To date, researchers have utilized disease resistance genes (R-genes) in different crops including cereals, pulses, and oilseeds and other economically important plants, to improve productivity. Interestingly, comparison of different R genes that empower plants to resist an array of pathogens has led to the realization that the proteins encoded by these genes have numerous features in common. The above observation therefore suggests that plants may have co-evolved signal transduction pathways to adopt resistance against a wide range of divergent pathogens. A better understanding of the molecular mechanisms necessary for pathogen identification and a thorough dissection of the cellular responses to biotic stresses will certainly open new vistas for sustainable crop disease management. This book summarizes the recent advances in molecular and genetic techniques that have been successfully applied to impart disease resistance for plants and crops. It integrates the contributions from plant scientists targeting disease resistance mechanisms using molecular, genetic, and genomic approaches. This collection therefore serves as a reference source for scientists, academicians and post graduate students interested in or are actively engaged in dissecting disease resistance in plants using advanced genetic tools.

Book Synopsis Bacterial Disease Resistance in Plants by : P. Vidhyasekaran
Download or read book Bacterial Disease Resistance in Plants written by P. Vidhyasekaran. This book was released on 2002-10-23. Available in PDF, EPUB and Kindle. Book excerpt: Examine the most recent developments in molecular plant pathology! This comprehensive reference book describes the molecular biology of plant-pathogen interactions in depth. With Dr. Vidhyasekaran’s keen insights and experienced critical viewpoint, Bacterial Disease Resistance in Plants: Molecular Biology and Biotechnological Applications not only presents reviews of current research but goes on to suggest future research strategies to exploit the studies in interventions with biotechnological, commercial, and field applications. This extraordinarily well-referenced book delivers in-depth examinations of: the molecular recognition process between plants and bacterial pathogens bacterial genes involved in the recognition process hrp, avr, dsp, and hsv genes the transcription of bacterial genes in plants signal transduction systems in bacteria and plants the functions of resistance genes and defense genes at the molecular level the elicitor molecules of bacterial pathogens and plants and their interactions plant and bacterial cell wall modifications and their role in triggering host defense mechanisms Bacterial Disease Resistance in Plants also explores active oxygen species, inducible plant proteins and their signals and transcription mechanisms, inducible secondary metabolites, and more. It introduces novel strategies for bacterial disease management using genes from human beings, birds, crabs, insects, fungi, bacteria, and bacteriophages; and genetic engineering techniques that can be used to develop transgenic, disease-resistant plants. Generously illustrated with figures and tables that make the data more quickly understandable, Bacterial Disease Resistance in Plants will be an invaluable resource and textbook for plant pathologists, bacteriologists, botanists, plant physiologists, plant molecular biologists, microbiologists, biochemists, plant cell and applied biologists, genetic engineers, and graduate-level students in these disciplines.

Book Synopsis Durability of Disease Resistance by : Th. Jacobs
Download or read book Durability of Disease Resistance written by Th. Jacobs. This book was released on 2012-02-02. Available in PDF, EPUB and Kindle. Book excerpt: From February 24 -28, 1992 an international symposium on Durability of Disease Resistance was held at the International Agricultural Centre in Wageningen, the Netherlands. The symposium, organized by the Department of Plant Breeding of Wageningen Agricultural University and the Centre for Plant Breeding and Repro duction Research, CPRO-DLO, was part of the DGIS funded programme Durable Resistance in Developing Countries. Without any form of prevention or protection nearly all crops will be seriously or even severely damaged by a range of pathogens. In modern agriculture man has been able to control many if not most pathogens using i) pesticides, ii) phyto sanitary methods such as control of seed and plant material in order to start a crop disease free, iii) agronomic measures such as crop rotation, iv) disease resis tance or combinations of these measures. Over the years the use of pesticides has increased enormously and so did the pro blems associated with pesticide use, such as environmental pollution and building of resistance and tolerance to these pesticides in the pathogens. The use of resis tance too increased strongly over the years and here too problems arose.
