    • Isolated polynucleotides and polypeptides encoded thereby are described, together with the use of those products for making transgenic plants with increased nitrogen use efficiency. The present invention further relates to nucleotide sequences and the use of those nucleotide sequences in the genetic-engineering of plants to display enhanced nitrogen assimilatory and utilization capacities, grow larger, more efficiently or rapidly, and/or have enriched nitrogen contents in vegetative and/or reproductive plant parts and/or increased biomass. More particularly, this invention relates to producing transgenic plants engineered to have altered expression of key components in the nitrogen assimilation and utilization pathways. The engineered plants may be productively cultivated under conditions of low nitrogen fertilizer input or in nitrogen poor soils. Alternatively, the engineered plants may be used to achieve faster growing or maturing crops, higher crop yields and/or more nutritious products under ideal cultivation conditions.
    • 描述了分离的多核苷酸和由此编码的多肽,以及这些产物用于制备具有增加的氮利用效率的转基因植物的用途。 本发明还涉及核苷酸序列和这些核苷酸序列在植物遗传工程中的用途,以显示增强的氮同化和利用能力,增长更大,更有效或快速,和/或在营养和/ 或生殖植物部分和/或增加的生物量。 更具体地说,本发明涉及生产工程改造为在氮同化和利用途径中改变关键成分表达的转基因植物。 工程植物可以在低氮肥输入条件下或在氮肥不足的土壤中有效栽培。 或者,工程植物可以用于在理想的栽培条件下实现更快的生长或成熟的作物,更高的作物产量和/或更有营养的产品。
