The Role of Phytotoxins in Specificity
In his lecture, Brian indicated that Phytotoxins which selectively damage plants susceptible to the pathogen involved provide the clearest examples of agents which determine specificity in plant-pathogen interactions. Five years ago, a preceding Institute was devoted entirely to the role of Phytotoxins in plant disease. In the published proceedings of the Institute, Graniti (8) addressed problems of terminology and classification of toxins associated with plant diseases. Without retracing that ground, I should like to discuss briefly two terms, pathotoxin and host-specific toxin.
