Sunflower disease resistance genes

摘要

Compositions and methods for enhancing disease resistance in plants are provided. Compositions comprise sunflower resistance gene analogs. The methods involve transforming a plant with a resistance nucleotide sequence. The methods find use in enhancing broad-based resistance in plants to pathogens. Also provided are transformed plants, plant cells, tissues, and seeds having enhanced disease resistance. The R gene analogs can be used as molecular markers for disease resistance.
