  • Disease resistance factors
    Publication number: 20030172411
    Abstract: This invention relates to isolated nucleic acid fragments encoding corn (Zea mays), rice (Oryza sativa), or wheat (Triticum aestivum) NPR1 homologs. The invention also relates to the construction of a chimeric gene encoding all or a portion of the NPR1 homolog, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the NPR1 homolog in a transformed host cell.
