Apple scab, caused by the fungus V. inaequalis, is one of the most damaging diseases in apple worldwide. In the present study, pathogen induced gene expression in leaves of the scab susceptible cultivar Golden Delicious and the resistant cultivar Rewena was analyzed. In order to further characterize the host-pathogen-interaction, the concentrations of defence-related phenolic compounds were examined. In addition, varying N-fertilization levels modified the degree of susceptibility of the Golden Delicious trees. The results suggested that the scab defence of the two cultivars is based on different mechanisms.
