  • Bacteria and method for controlling plant disease using the same
    Patent number: 8728459
    Abstract: An object of the present invention is to provide a means for imparting resistance against pathogenic fungal, pathogenic bacterial, or pathogenic viral disease to agriculturally useful plants. The present invention relates to a bacterium belonging to the genus Azospirillum or the genus Herbaspirillum capable of imparting resistance against pathogenic fungal, pathogenic bacterial, or pathogenic viral disease to a host plant by living symbiotically within the plant, a method for controlling plant disease using the bacteria, and plants produced by such method.

  • Rice containing endophytic bacteria and method of producing it
    Patent number: 7084331
    Abstract: The present invention provides a rice plant that shows enhanced growth and increased seed production, which also enables reduction of the use of chemical fertilizers. In the present invention, a nitrogen-fixing endophytic bacterium is isolated from bacteria symbiotically inhabiting natural plants, the isolated endophytic bacterium is artificially proliferated and then artificially inoculated into rice plants, and thus, the nitrogen-fixing endophytic bacteria are allowed to infect to rice plants.

  • Pest control method for grass family plants using endophytic bacteria, pest control material, and seed bound to the pest control material
    Patent number: 7037879
    Abstract: The objective of the present invention is to confer pest resistance to plants of Poaceae without using any chemically synthesized pesticides. The pest resistance can be conferred to plants of Poaceae by isolating from a natural plant an endophytic bacterium capable of expressing pest resistance, artificially culturing the endophytic bacterium, and introducing the bacteria to a Poaceae plant of interest.
