Advances in the understanding of cellular processes at the molecular level have transformed the biological sciences. Plant pathology is a field which has benefited dramatically from the application of molecular techniques and has become one of the most exciting areas of biology today. Molecular Plant Pathology: A Practical Approach Volume I and its companion Volume II provide the first comprehensive guide to the latest molecular techniques as well as the established approaches to the subject. Detailed protocols are included which address a wide range of investigations from plant pathogen isolation and culture, through physiology and biochemistry, to techniques for localizing genes and their products within the cells of the infected plants. Researchers in plant science, molecular biology, and related areas will find the two volumes of Molecular Plant Pathology to be an invaluable experimental resource, providing a wealth of easy-to-follow protocols supported by expert advice and guidance.
