Beschreibung
Zusammenfassung:	This invention describes a method to induce pathogen resistance in plants, characterized in that plants are transformed with an expression cassette harboring a gene coding for an isochorismate synthase. More specifically, th is method is characterized in that the gene coding for isochorismate synthase i s selected from a group consisting of entC, orfA, pchA and ICS, this last gene preferably the ICS gene from Catharantus roseus. Another embodiment of the invention is a method according to the method described above, characterized in that plants are additionally transformed with an expression cassette harboring a gene coding for an isochorismate pyruvate lyase, preferably on t he same expression cassette as the gene coding for isochorismate synthase. The gene coding for isochorismate pyruvate lyase is preferably selected from the group consisting of orfD and pchB. A further aspect of the invention is a protein having isochorismate synthase activity which is isolated from Catharantus roseus. Still a further aspect of the invention is the nucleotid e sequence comprising the 5' regulatory region which is naturally found to regulate the expression of the ICS gene in Catharantus roseus.
