MODIFICATION OF A PLANT DISEASE RESISTANCE GENE SPECIFICITY AND METHOD FOR ENGINEERING ALTERED SPECIFICITY

摘要

This invention concerns the preparation and use of an isolated nucleic acid fragment in order to confer a resistance gene mediated defense response in plants against a fungus comprising in its genome virulent and/or avirulent AVR-Pita alleles. Chimeric genes incorporating such fragments or functionally equivalent subfragments thereof and suitable regulatory sequences can be used to create transgenic plants which can produce a resistance gene mediated defense response against a fungus comprising in its genome virulent and/or avirulent AVR-Pita alleles.
