Disease resistance in plants pdf
PDF Disease resistance is often defined as reduction of pathogen growth on or in the plant. It denotes less disease development in a genotype than that in the susceptible variety and is aDisease 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. disease resistance in plants pdf
Plant Disease Resistance Genes Jeffrey G. Ellis and David A. Jones 1. INTRODUCTION No adaptive immune system equivalent to the highly effective vertebrate immune system has been detected in plants. Nevertheless, the very existence of plants in the Plant Resistance to Disease 29 Fig. 1. Growth () or no growth () of the ax rust fungus
As resistance is by far the most important defence of plants against pathogens this chapter discusses the various aspects of disease resistance. MEASURING RESISTANCE Selection for resistance implies measurements of plant resistance. Disease control is achieved by use of plants that have been bred for good resistance to many diseases, and by plant cultivation approaches such as crop rotation, pathogenfree seed, appropriate planting date and plant density, control of field moisture, and pesticide use. disease resistance in plants pdf Mapping QTLs is an effective approach for studying plant disease resistance. The first step in mapbased cloning is to place molecular markers that lie near a gene of interest and cosegregate with the proposed gene without recombination.
