Abstract

Ethylene has been observed to both inhibit and promote the symptoms of Verticillium wilt (caused by Verticillium dahliae) in tomato. To test the hypothesis that ethylene has different effects at different stages in the infection process, ethylene levels were manipulated in V. dahliae-infected tomato plants by the application of an ethylene synthesis inhibitor aminoethoxyvinylglycine (AVG) and/or ethylene's biosynthetic precursor 1-aminocyclopropane-1-carboxylate (ACC) and the effects on disease severity were examined. Statistically significant reductions in disease severity were consistently obtained for AVG-treated plants that had ACC added at the time of inoculation. A model is therefore proposed in which post-infection ethylene enhancesVerticillium wilt development in tomato whereas its presence at the time of infection inhibits disease development.
