Resistance mechanisms in Lycopersicon spp. to Oidium neolycopersici

Popis výsledku v původním jazyce

Limited information on the resistance mechanisms in Lycopersicon spp. (e.g. L. hirsutum, L. peruvianum) to O. neolycopersici is still available. Macroscopically the resistance is characterized by a very low amount of mycelium development and a lack of sporulation. The leaf surface did not effectively inhibited conidium germination, however significant differences in germ tube and appressorium development were recorded. A large variation was observed in host tissue response. The prevailing resistance mechanism was hypersensitivity (HR). The existence of other resistance mechanisms, not based on HR, was confirmed as well. Considerable changes of peroxidase and catalase activities during pathogenesis were detected among tested wild Lycopersicon spp. Therewas positive correlation between increasing of peroxidase activity and extent of necrosis. Histochemistry showed large differences in production of superoxid ions, hydrogen peroxide and peroxidase in Lycopersicon spp. with various level o
