Provided are methods of increasing nitrogen use efficiency, fertilizer use efficiency, yield, growth rate, vigor, biomass, oil content and/or abiotic stress tolerance of a plant by expressing within the plant an exogenous polynucleotide comprising a nucleic acid sequence at least 80% identical to SEQ ID NO: 2506, 2512, 2442, 2496, 2446, 1, 2, 4, 7, 8, 11, 12, 13, 16-19, 21-60, 63-128, 130-137, 270-287, 289-293, 295-306, 308-362, 364-666, 671, 673-1333, 2414-2441, 2443-2445, 2447-2455, 2458-2495, 2497-2505, 2507-2511, 2513-2521 or 2522; and of increasing nitrogen use efficiency, fertilizer use efficiency and/or oil content of a plant by expressing within the plant an exogenous polynucleotide comprising a nucleic acid sequence at least 80% identical to SEQ ID NO: 3, 5, 6, 9, 10, 14, 15, 288, 294, 2398-2412 or 2413. Also provided are isolated polynucleotides and polypeptides which can be used to increase nitrogen use efficiency, fertilizer use efficiency, yield, growth rate, vigor, biomass, oil content and/or abiotic stress tolerance of a plant of a plant. |

1. A method of increasing nitrogen use efficiency, and/or tolerance to nitrogen deficiency of a plant, comprising:
(a) expressing within the plant an exogenous polynucleotide comprising a nucleic acid sequence encoding a polypeptide selected from the group consisting of SEQ ID NOs: 2557, 248, 2349, 2350, 2351, 2352 and 2353, and; (b) selecting plants resulting from step (a) for an increased nitrogen use efficiency, and/or increased tolerance to nitrogen deficiency as compared to a native plant of the same species, which is grown under the same growth conditions, thereby increasing the nitrogen use efficiency, and/or tolerance to nitrogen deficiency of the plant as compared to the native plant of the same species, which is grown under the same growth conditions. |
