METHOD OF CONSTRUCTING PLANT SHOWING IMPROVED GROWTN UNDER REGULATION OF NITROGEN

摘要

The present invention provides a method of producing a plant exhibiting improved growth and/or yield under conditions where nitrogen is reduced, that is, under cultivation conditions where nitrogen is limited compared as the ordinary cultivation conditions, by increasing 2-OG content in plants. Particularly, The present invention provides a method of producing a plant exhibiting improved growth and/or yield under conditions where nitrogen is reduced, that is, under cultivation conditions where nitrogen is limited compared as the ordinary cultivation conditions, by introducing a GDH gene or ECASPC gene into plants and expressing the transgene GDH or ECAPS in the plants to increase 2-OG or by spraying proline on the leaves of plants to increase 2-OG content, thereby enhancing the incorporation of nitrogen or metabolic activity of plants. Also provided is a method of cultivating such plants under nitrogen-limited conditions.
