Abstract
The present invention relates to novel antipathogenic peptides, to DNA sequences encoding said peptides, to vectors comprising said DNA sequences, to transgenic plants comprising a DNA sequence encoding said peptides, to compositions containing anti-pathogenic peptides and to the use of said peptides and compositions for controlling plant pathogens, Also comprised are methods of preparing antipathogenic peptides or compositions containing same and transgenic plants able to synthesize anti-pathogenically effective amounts of said peptides.
Claims23
An isolated DNA comprising a sequence encoding amino acids according to SEQ. ID No. 1, 2, 3, 4, 5, or 6.
A recombinant DNA comprising a peptide-encoding sequence wherein the peptide-encoding sequence encodes a peptide according to SEQ ID No. 1, 2, 3, 4, 5, or 6.
A method of preparing a transgenic plant which is able to synthesize anti-pathogenically effective amounts of an active ingredient comprising a peptide having an amino acid sequence comprising SEQ ID NO. 3, 4 or 5, wherein the method comprises:
- a) preparing a transgenic plant comprising recombinant DNA sequences encoding said peptide and optionally a lytic peptide;
- or
- b) preparing two or more transgenic plants comprising recombinant DNA sequences encoding said peptide and optionally a lytic peptide and crossing said plants using conventional breeding techniques.
An isolated DNA comprising a sequence encoding 11 consecutive amino acids set forth in any one of SEQ. ID Nos. 4 or 5.
An isolated DNA comprising a sequence encoding 23 consecutive amino acids set forth in SEQ. ID No. 4.
