POLYPEPTIDES ET POLYNUCLEOTIDES ISOLES UTILES POUR AUGMENTER L'EFFICACITE DE L'UTILISATION DE L'AZOTE, LA TOLERANCE AU STRESS ABIOTIQUE, LE RENDEMENT ET LA BIOMASSE DE PLANTES
Provided are methods of increasing nitrogen use efficiency, fertilizer useefficiency, yield, growth rate, vigor,biomass, oil content and/or abiotic stress tolerance of a plant by expressingwithin the plant an exogenous polynucleotide comprisinga 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 nitrogenuse efficiency, fertilizer use efficiency and/oroil content of a plant by expressing within the plant an exogenouspolynucleotide 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 andpolypeptides which can be used to increase nitrogen use efficiency, fertilizeruse efficiency, yield, growth rate, vigor, biomass, oilcontent and/or abiotic stress tolerance of a plant of a plant.
