ISOLATED POLYPEPTIDES,POLYNUCLEOTIDES USEFUL FOR MODIFYING WATER USER EFFICIENCY,FERTILIZER USE EFFICIENCY,BIOTIC/ABIOTIC STRESS TOLERANCE,YIELD AND BIOMASS IN PLANTS
Polynucleotides, polypeptides, plant cells expressing same and methods of using same for increasing abiotic stress tolerance water use efficiency (WUE), fertilizer use efficiency (FUE), biomass, vigor and/or yield of a plant. The method is effected by expressing within the plant an exogenous polynucleotide encoding a polypeptide comprising an amino acid sequence at least 80% homologous to the amino acid sequence selected from the group consisting of SEQ ID NOs:33, 34, 30, 27-29, 31, 32, 35-52, 1401-1403, 1405-1435, 1437-1494, 1496-1542, 1544-1553, 1555-1559, 1561-1827, 1829-1866, 1868-2450, 2453-2458, 2460-2463, 2465-2481, 2483, 2485-2746, 2765-2769, 3052-3065 and 3067-3259, thereby increasing the water use efficiency (WUE), the fertilizer use efficiency (FUE), the biomass, the vigor and/or the yield of the plant.
