METHOD FOR PRODUCING A PLANT HAVING A DISEASE-RESISTANT PHENOTYPE DUE TO CONSTITUTIVE EXPRESSION OF A PATHOGENESIS - RELATED PROTEIN, AND TRANSGENIC PLANT PRODUCED THEREBY

摘要

A method for producing a plant having a disease-resistant phenotype, comprising: (a) transforming plant tissue or cells within a chimeric DNA sequence comprising a first DNA sequence comprising a promoter which promotes in a plant the constitutive transcription of an associated DNA sequence, operably linked to a second DNA sequence comprising a coding sequence encoding an inducible plant pathogenesis-related protein, wherein the said pathogenesis-related protein is not a chitinase; (b) constitutively expressing the pathogenesis-related protein at a level sufficient to provide a disease-resistant phenotype to the plant transformed in accordance with step (a); and (c) selecting those plants that exhibit a diesease-resistant phenotype, wherein said disease is caused by pathogenic fungi. 642 כ" א באייר התשס" ד - May 12, 2004
