    Die Hypersensibilität der Europäischen Pflaume (Prunus domestica L.) gegenüber dem Scharkavirus (Plum pox virus)
    (2005) Neumüller, Michael; Wünsche, Jens Norbert
    In terms of economic damage, Sharka is the most important virus disease in stone fruit crops. The causative agent of this disease is the Plum pox virus (PPV). Some genotypes of European plum (Prunus domstica L.) show a hypersensitive response when infected with PPV. Results about the inheritance of this type of resistance mediated by hypersensitivity and different types of symptoms characteristic for the hypersensitive defence response in the interavtion PPV/Prunus domestica are presented. From the biochemichal point of view, it is shown that the defence response is indeed a hypersensitive response. A strategy for the development of DNA markers for hypersensitivity to PPV in European plum is developed. The potential use of hypersensitivity for solving the Sharka problem is discussed.
