Abstract: A transgenic plant comprising a polynucleotide encoding a nitrogen utilization protein operably linked to a PBpr1 promoter is provided. The transgenic plant exhibits increased nitrogen use efficiency, increased biomass and/or increased seed yield. Seeds from such transgenic plants, genetic constructs to prepare such plants, methods of generating and growing transgenic plants are also provided.

Abstract: Methods are provided for enhancing yield and nitrogen use efficiency in plants, and to methods of increasing biomass and seed yield in plants grown under nitrogen limiting conditions using variants of enzymes involved in nitrogen assimilation or metabolism from non-plant organisms.

Abstract: Methods of increasing nitrogen utilization efficiency in monocot plants through genetic modification to increase the levels of alanine aminotransferase expression and plants produced there from are described. In particular, methods for increasing the biomass and yield of transgenic monocot plants grown under nitrogen limiting conditions compared to non-transgenic plants are described. In this way, monocot plants may be produced that maintain a desired yield while reducing the need for high levels of nitrogen application.

Abstract: Methods are provided by which Oryza sativa plants and seeds thereof may be modified to express a coding region of interest using a promoter sequence operatively linked to the coding region. The promoter sequence is an isolated Oryza sativa antiquitin (OsAnt1) promoter sequence including SEQ ID NO: 1. The coding region of interest may encode a nitrogen utilization protein, suitably alanine aminotransferase. Methods to develop Oryza sativa plants that have increased biomass and seed yield are also presented. Furthermore, Oryza sativa plants may be produced that maintain a desired yield while reducing the need for high levels of nitrogen application.

Abstract: 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.

Abstract: 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.
