Transgenic plants containing recombinant barley alanine aminotransferase are described. Also provided are methods for generating transgenic plants containing recombinant barley alanine aminotransferase.

Transgenic plants expressing recombinant barley alanine aminotransferase

The present invention relates to non-naturally occurring plants that display enhanced agronomic characteristics due to elevated levels of nitrogen utilization proteins in the root of the plants. In particular, the present invention relates to non-naturally occurring plants with elevated levels of nitrogen utilization proteins specifically localized to the root epidermis of the plant. In addition, the present invention includes a preferred method of generating such non-naturally occurring plants by introducing into the plant a transgene encoding a nitrogen utilization protein operably linked to a root-epidermis-specific promoter.

Plants with enhanced levels of nitrogen utilization proteins in their root epidermis and uses thereof

A genetic construct is taught which contains a nitrogen assimilation and/or metabolism gene and a promoter for the gene which is inducible under conditions where it would be beneficial to take-up, store or use nitrogen. The promoter can be, for example, induced by the presence of nitrate or other form of nitrogen and will be induced by application of a nitrogenous fertilizer. The stress inducible promoter btg-26 is also taught. Promoter btg-26 is isolated from the Brassica turgor gene--26 and exhibits osmotic-stress induced expression.
