Abstract:
A method for the induction of pathogen resistance in a plants, comprising:(a) providing a polynucleotide sequence encoding a constitutively active mutated ndr1 protein, wherein the mutation consists of an amino acid substitution at a position relative to SEQ ID NO. 14 selected from the group consisting of Ser-20, Ser-35, Thr-94, Thr-164 and Ser-207; (b) producing a chimeric DNA sequence by operably linking said polynucleotide sequence to a pathogen-inducible promoter; (c) transforming a plant cell with said chimeric DNA sequence; (d) regenerating from said plant cell a plant wherein infection of said plant by a pathogen causes activation of said pathogen-inducible promoter, said activation resulting in expression of said constitutively active mutated ndr1 and wherein said expression gives rise to a hypersensitive response.
