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.
Claims12
A rice plant produced by artificially introducing an endophytic bacterium into a rice plant that is free of endophytic bacteria, wherein said introduced endophytic bacteria is Herbaspirillum FERM BP-10395 or Azospirillum FERM BP-10447, which have been deposited in the National Institute of Advanced Industrial Science and Technology.
An isolated bacterium selected from the group consisting of a bacterium deposited as accession number FERM BP-10395 and a bacterium deposited as accession number FERM BP-10447, both deposited at the National Institute of Advanced Industrial Science and Technology.
A method for introducing an endophytic bacterium into a rice plant, comprising the following steps of:
- isolating and proliferating an endophytic bacterium which inhabits a plant;
- artificially inoculating the artificially proliferated endophytic bacteria into the rice plant;
- and
- infecting the rice plant with the artificially inoculated endophytic bacteria to form a symbiosis, wherein said introduced endophytic bacteria is Herbaspirillum FERM BP-10395 or Azospirillum FERM BP-10447, which have been deposited in the National Institute of Advanced Industrial Science and Technology.
