Summary
Plant diseases are destructive and threaten virtually any crop grown on a commercial scale. They are kept in check by plant breeding strategies that have introgressed disease resistance genes into many important crops, and by the deployment of costly control measures, such as antibiotics and fungicides. However, the capacity for the agents of plant disease - viruses, bacteria, fungi, and oomycetes - to adapt to new conditions, overcoming disease resistance and becoming resistant to pesticides, is very great. For these reasons, understanding the biology of plant diseases is essential for the development of durable control strategies.
Plant-Pathogen Interactions provides and overview of our current knowledge of plant-pathogen interactions and the establishment of plant disease, drawing together fundamental new information on plant infection mechanisms and host responses. The role of molecular signals, gene regulation, and the physiology of pathogenic organisms are emphasized, but the role of the prevailing environment in the conditioning of disease is also discussed.
Emphasizing the broader understanding that has emerged from the use of molecular genetics and genomics, Plant-Pathogen Interactions highlights those interactions that have been most widely studied and those in which genome information has provided a new level of understanding.

Editorial Reviews
"This neat collection of nine strong and competent reviews brings together … recent studies … . There is sufficient background material for readers to obtain a good understanding of the parasite and its infection process, and the reviews are illustrated by … figures that are clear and strategically placed. … I find that this volume will be very useful for both inspired undergraduates who plan on initiating honors studies or independent research, and for beginning graduate students. … I am requiring this textbook for ecological and evolutionary geneticists. This primer will help young biologists learn the nuts and bolts of ecological genetics, as well as its practical applications."
- Quarterly Review of Biology, Vol. 80, March 2005
"[Talbot's] contribution is authoritative and forward looking, and should be read by all advanced undergraduate students and researchers interested in the biology of plant-pathogen interactions…[Hirano & Upper] have adopted an engaging and questioning approach, resulting in an essay that promises to inspire fungal as well as bacterial phytopathologists…well-written and edited…I recommend this book for purchase by libraries where it will be available to readers new to the pathogens described and to others who want authoritative and recent reviews of the literature."
