Phytotoxins and Plant Pathogenesis [Paperback]

Proceedings of the NATO Advanced Research Workshop on Phytotoxins and Plant Pathogenesis held at Capri, Italy, May 30 - June 3, 1988Session I  Structure and Some Biological Aspects of Phytotoxins.- 1. Current research into chemical synthesis of phaseolotoxin.- 2. Structural studies on host-specific phytotoxins in corn blight and citrus brown spot disease.- 3. Biosynthesis and regulation of toxins produced by Pseudomonas syringae pv. glyci nea (coronatine) and Pseudomonas andropogonis (rhizobiotoxine).- 4. Biological activities of structural variants of host-selective toxins from Cochliobolus victoriae.- Session 2  Genetic Aspects of Toxin Production.- 1. Genetic analysis of toxin production in fungi.- 2. Identification and isolation of a DNA region required for tabtoxin production: apparent deletion in Pseudomonas syringae pv. tabaci variant angulata and tox- mutants.- 3. Ornithine carbamoyl transferase gene duplication and phaseolotoxin resistance in Pseudomonas syringae pv. phaseolicola.- 4. Cloning and characterization of genes encoding phaseolotoxin, the toxin produced by Pseudomonas syri ngae pv. phaseolicola.- 5. A novel toxin produced by Pseudomonas corrugata, the causal agent of tomato pith necrosis: determination of its role in virulence and the genetics of production.- 6. Mode and physiological consequence of AAL-toxin interaction with the asc locus in tomato.- Session 3  Mode of Action of Phytotoxins and Effects on Plants.- 1. Fusicoccin-receptor interaction and activation of plasma membrane H+-ATPase in native membrane vesicles.- 2. Action of fusicoccin in vivo: physiological and biochemical consequences.- 3. Mode of action of fusicoccin: the role of specific receptors.- 4. Interactions of Phytotoxins with plant cell membranes: electrophysiology and ion flux-induced pH changes.- 5. Syringomycin effects on plasma membrane Ca+2 transport.- 6. Extracellular polysaccharides as determinants of leaf spot diseases caused by pseudomonads and xanthomonads.- l#º
