USE OF PLANT-DERIVED DHAR OR MDHAR GENE AS A MODULATOR FOR CROP YIELD AND ENVIRONMENTAL STRESS

摘要

The present invention relates to a method for increasing crop yield or enhancing resistance of a plant to environmental stress by using dhar (dehydroascorbate reductase) gene derived from rice (Oryza sativa) or mdhar (monodehydroascorbate reductase) derived from Chinese cabbage (Brassica rapa), a method of producing a transgenic plant with increased crop yield or enhanced resistance to environmental stress by using dhar gene or mdhar gene, a transgenic plant with increased crop yield or enhanced resistance to environmental stress that is produced by the aforementioned method, and a seed thereof, and a composition for increasing crop yield or enhanced resistance to environmental stress containing dhar gene or mdhar gene.
