Molecular plant pathology has directly benefited from advances in modern molecular techniques. These techniques have been applied both to pathogens and plants, enhancing our understanding of the organisms themselves and of the complex interactions which determine compatibility between them and their host plants. This volume and its companion together provide the first comprehensive guide to the latest molecular techniques as well as the established approaches to the subject. Researchers in plant science, molecular biology, and related areas will find the two volumes of Molecular Plant Pathology to be an invaluable experimental resource for this expanding field, providing a wealth of easy to follow protocols supported by expert advice and guidance.
