Abstract
Methods are provided for selecting parental plants having disease resistance and for using these plants in breeding programs. In one method of the invention, lesion mimic mutants are screened for either resistance to a pathogen of interest or for the expression of systemic acquired resistance (SAR) genes. Such mutants having the desired traits or expressing the desired genes are then used in breeding programs. Parent plants can also be selected based on the constitutive expression of SAR genes. These mutants are phenotypically normal yet exhibit a significant level of disease resistance. Also disclosed are plant mutants that do not express systemic acquired resistance genes even when induced by a pathogen and methods of use for such mutants.
