Compositions and methods to aid in protecting plants from invading pathogenic organisms are provided. The compositions of the invention comprise an anti-pathogenic gene, including the promoter driving expression of the gene, and the protein encoded by the anti-pathogenic gene. The compositions find use in methods for reducing or eliminating damage to plants caused by plant pathogens. Transformed plants, plant cells, tissues, and seed are also provided having enhanced disease resistance.

Compositions and methods for enhancing disease resistance in plants are provided. The method involves transforming a plant with an avirulence gene or alternatively with an avirulence gene and the complementing resistance gene. A pathogen inducible promoter or alternatively a weak constitutive promoter is used to control the desired level of disease control in the plant. Transformed plants, plant cells, tissues, and seed are also provided having enhanced disease resistance.

Methods for enhancing disease resistance in plants

The invention provides isolated NPR1 nucleic acids and their encoded proteins. The present invention provides methods and compositions relating to altering NPR1 concentration and/or composition of plants. The invention further provides recombinant expression cassettes, host cells, and transgenic plants. Additionally, the present invention provides promoter elements capable of initiating constitutive expression in a plant. Further, the present invention provides for methods for screening putative activators of a plant resistance pathway.
