Isolated Polypeptides and Polynucleotides Useful For Increasing Nitrogen Use Efficiency, Abiotic Stress Tolerance, Yield and Biomass In Plants

摘要

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 5 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 LO 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.
