Plants having an enhanced amino acid content, plants having an enhanced nitrogen content, plants tolerant to nitrogen deficiency, and methods for producing them

摘要

The object of the present invention is to provide a transformed plant having an enhanced amino acid content, a progeny of the plant, seeds of the plant and a method for producing the plant. The present invention provides a transformed plant having a gene encoding DNA binding protein of Dof family and also having a free amino acid content higher than that of naturally occurring plants of the same species cultivated under the same conditions. The present invention also provides a method of producing a transformed plant having the free amino acid content higher than that of naturally occurring plants of the same species cultivated under the same conditions by introducing a gene encoding DNA binding protein of Dof family into the plant to express the gene in the plant body.
