The Advanced Text series is designed for students taking advanced-level courses, including final year undergraduates and taught MSc. Titles in this series will also be invaluable to researchers new to the field, and to established researchers as a basic reference text. Studies of the interactions between plants and their viral, bacterial and fungal pathogens are of major importance in plant and crop production. More than 10 per cent of potential agricultural yield is lost to these organisms annually worldwide, and major epidemics can cause significant local economic and environmental damage. Molecular Plant Pathology addresses the underlying molecular principles of plant/pathogen interactions, in a readily-accessible textbook format.
