  • Control of bacterial infection by quenching quorum-sensing of plant pathogenic bacteria
    Publication number: 20040139495
    Abstract: Transgenic plants, protected from bacterial pathogens, which harbor the aiiA gene or a functional fragment or a modification thereof and express functional AiiA protein were produced. The plants and plant materials of this invention inactivate bacterial pathogen quorum-sensing signal molecules, thereby eliminating or reducing the production of bacterial virulence factors which are harmful to plant cells and tissues.
