Abstract: The present invention includes an antimicrobial peptide consisting of, consisting essentially of, or comprising, at least one of SEQ ID NO:1-20, nucleic acids encoding the peptides, methods for using the antimicrobial peptide generating plants which express the peptides sufficient to endow the plants with resistance to pathogenic bacteria and fungi, the use of the nucleic acids to produce peptides by cellular production such as fermentation or plant production systems of the antimicrobial peptide(s), and the use of the isolated antimicrobial peptide(s) in a spray or other mixture to treat plants to protect them from disease.
