Technical Abstract: A 24 kDa protein produced by Fusarium oxysporum f.sp. erythroxyli causes necrosis and/or ethylene production in most dicots, and does not appear to affect monocots. It has been characterized in tobacco as an HR-like response. Similar systems have been shown to induce resistance in plants. We are currently evaluating the 24 kDa protein with regard to its ability to induce resistance both locally and systemically. The 24 kDa protein appears to be having long term effects on tomato plants. The plant responses to the protein are currently being characterized. Disease development of several Colletotricum species on cucumber, tomato, alfalfa, cotton, potato, and watermelon; Alternaria on tomato; and Rhizoctonia and Pythium on cucumber are being evaluated on plants treated with the elicitor. The resulting data will be presented and discussed.
