ISOLATED POLYNUCLEOTIDES AND POLYPEPTIDES AND METHODS OF USING SAME FOR INCREASING PLANT YIELD, BIOMASS, GROWTH RATE, VIGOR, OIL CONTENT, ABIOTIC STRESS TOLERANCE OF PLANTS AND NITROGEN USE EFFICIENCY

摘要

Provided are isolated polynucleotides encoding a polypeptide at least 80% homologous to the amino acid sequence selected from the group consisting of SEQ ID NOs: 799, 488-798, 800-813, 4852-5453, 5460, 5461, 5484, 5486-5550, 5553, and 5558-8091; and isolated polynucleotide comprising nucleic acid sequences at least 80% identical to SEQ ID NO: 460, 1-459, 461-487, 814-1598, 1600-1603, 1605-1626, 1632-1642, 1645-4850 or 4851. Also provided are nucleic acid constructs comprising same, isolated polypeptides encoded thereby, transgenic cells and transgenic plants comprising same and methods of using same for increasing yield, biomass, growth rate, vigor, oil content, fiber yield, fiber quality, abiotic stress tolerance, and/or nitrogen use efficiency of a plant. Also provided are isolated polynucleotides comprising the nucleic acid sequence set forth by SEQ ID NO:8096, wherein the isolated polynucleotide is capable of regulating expression of at least one polynucleotide sequence operably linked thereto.

1. A method of increasing yield, biomass, growth rate, vigor, oil content, fiber yield, fiber quality, abiotic stress tolerance, and/or nitrogen use efficiency of a plant, comprising over-expressing within the plant a polypeptide comprising an amino acid sequence as set forth by SEQ ID NO: 799, 488-500, 502-798, 800-813, 4852-5453, 5460, 5461, 5484, 5486-5550, 5553, 5558-8090 or 8091, or a homologous polypeptide thereof which exhibits at least 80% sequence identity to said amino acid sequence, wherein said homologous polypeptide increases yield, biomass, growth rate, vigor, oil content, fiber yield, fiber quality, abiotic stress tolerance, and/or nitrogen use efficiency of a plant, thereby increasing the yield, biomass, growth rate, vigor, oil content, fiber yield, fiber quality, abiotic stress tolerance, and/or nitrogen use efficiency of the plant.
