A three-step screening of selection for resistance against pathogenic bacteria infection, selection for resistance against pathogenic fungi infection, and selection for sensitivity to salicylic acid was carried out onlines highly expressing rice full-length cDNA (rice-FOXlines) which were prepared by using a FOX hunting system. As a result, oneline (line K15424) selected in all of the three types of screening was successfully selected. Line K15424 carries a rice full-length cDNA. Rice overexpressing AK070024 was produced, and resistance against rice bacterial leaf blight was assayed using the T1 generation. As a result, it was confirmed that AK070024-overexpressing rice is resistant against bacterial leaf blight and blast.

Rice gene capable of imparting wide-spectrum disease resistance

The present invention relates to methods of producing transgenic plants having resistance to blast fungus and/or leaf-blight bacteria by transforming the plants with a DNA encoding a protein that induces hypersensitive reaction-like lesion mimic, and transgenic plants, plant cells, seed and progeny having resistance to blast fungus and/or leaf-blight bacteria.
