Abstract
A method for the protection of plants against pathogens, wherein a polynucleotide sequence comprising at least a sequence of a pathogenic avirulence gene (E) encoding a specific elicitor protein molecule (e) or a portion thereof is introduced into the genome of a plant containing a corresponding resistance gene (R), in which genes (E) and (R) are regulated in such a manner that simultaneous expression of said genes only occurs at the site of infection and said simultaneous expression can be induced by a broad range of pathogens. A polynucleotide sequence comprising at least a sequence of an avirulence gene (E) from a plant pathogen encoding a specific elicitor protein molecule (e) or a portion thereof, and a plant promoter (P) that can be induced by a broad range of pathogens and which permits expression at the site of infection only. Plant obtainable by use of said method and plant comprising said polynucleotide sequence.
