Synopsis Plant pathology is an issue of direct relevance to crop yield and hence of major economic importance. Having a thorough and comprehensive knowledge of pathogens causing plant diseases, their symptoms, effects and treatment is essential part of the curriculum of a student in the field of plant science. The invaluable resource on plant pathology introduces the types of organisms causing plant diseases, ranging from higher plants to viroids. Techniques that may be of use in studying plant infections, such as colloidal gold cytochemistry, in situ hybridisation, etc., are detailed, and the defence mechanisms of infected plants, including trees, cytolocalisation of molecules involved in host resistance, have also been discussed. With an up-to-date account of the latest trends and developments in plant pathology, and a lucid style of writing, the book is a must for academicians, researchers and students in the field of agroscience, botany and plant science.
