Ebook: Molecular Genetics of Host-Specific Toxins in Plant Disease: Proceedings of the 3rd Tottori International Symposium on Host-Specific Toxins, Daisen, Tottori, Japan, August 24–29, 1997

For investigators engaged in the study of toxins generally, and host-specific toxins in particular, it is a rare treat to attend a meeting in which toxins involved in plant pathogenesis are emphasized. A gathering of this type provides opportunity to consider the discovery of new toxins, their chemical structures, genes encoding enzymes that control their biosyntheses, their sites of action and physiological effects on plants, and their roles (if any) in pathological processes. Having acknowledged the inspiration fostered by a 'toxin meeting', however, it is important to point out that the program of this symposium was generously sprinkled with 'nontoxin' talks. These contributions generated cross-disciplinary discussion and promoted new ways of thinking about relationships among factors required for plant disease development. The point can be illustrated by considering just one example. We have in the past often regarded diseases mediated by host-specific toxins and diseases involving 'gene-for-gene' relationships as representing two different classes of fungal/plant interaction. This is largely because the key molecular recognition event in so-called 'toxin' diseases leads to compatibility, whereas the corresponding event in 'gene-for-gene' diseases leads to incompatibility. Yet the race specific elicitors produced by the 'gene-for-gene' fungi Cladosporium fulvum (De Wit, Adv. Bot. Res. 21:147- 185, 1995) and Rhynchosporium secalis (Rohe et a1. , EMBO J.

The Tottori International Symposia on Host-Specific Toxins were established in 1988 by the Tottori University Faculty of Agriculture to provide an interdisciplinary forum for scientists working in rapidly emerging areas of studies of plant-fungal pathogen interactions, especially involving host-specific toxins and related pathogenicity factors.
Molecular Genetics of Host-Specific Toxins in Plant Disease is the proceedings of the 3rd international symposium on host-specific toxins held in August 1997 in Tottori, Japan. Up-to-date material is presented in rapidly developing research areas such as new toxins, fungal genes for toxin biosynthesis, evolution of pathogenic strategies, toxin actions on plants, toxin receptors, signal transduction, oxidative burst, mechanisms of sensing, penetration and host degradation, apoptosis triggered by toxins, and plant genes for detoxification. This information has given researchers penetrating insights into various aspects in the field.
Molecular Genetics of Host-Specific Toxins in Plant Disease will be a valuable up-to-date reference for researchers and students in the areas of plant pathology, plant protection, plant physiology and molecular biology, fungal molecular genetics, and plant breeding and biotechnology.
