The present invention discloses the production of transgenic plants that exhibit a systemic acquired resistance (SAR) response even in the absence of an infecting pathogen. The transgenic plants are produced by a method comprising obtaining a plant having a first nucleic acid molecule encoding one or more protein products of the N gene sufficient to confer resistance to a phytopathogen and introducing into the genome of said plant a second nucleic acid molecule encoding the TIR domain of the N gene, wherein co-expression of the first and second nucleic acid molecules is sufficient to produce a systemic acquired resistance response in the plant in the absence of an infecting pathogen. The invention encompasses such plants, methods and biological molecules useful for producing the plants, and methods for increasing the disease resistance of plants.
