And ISOLATED POLYNUCLEOTIDES， POLYPEPTIDES and METHODS FOR THEIR USE IN THE INCREASE OF YIELD OF PLANTS and THE AGRICULTURAL CHARACTERISTICS

Claim 1: One method for increasing the yield， biomass， growth rate of growth， vigor， of oil content， yield of fiber， the quality of the Fiber， tolerance to the abiotic stress and/or efficiency in the use of nitrogen， and/or reduce the time to flowering or the emergence of inflorescence of the plant， an Characterized in that comprising transforming one of the plant cell with one that comprising an exogenous polynucleotide sequence of nucleic acid that is， to the less， 80 % identical to SEQ ID no: 3487， 1-24， 26-239， 467-917， 919-1973， 3481-3486， 3488-3504， 3506-3674， 3738 or 3739， where the plant obtained by the method of protection， is excluded Thereby increasing the yield， biomass， growth rate of growth， vigor， content of oil， performance of the fiber， tolerance to the abiotic stress and/or efficiency in the use of nitrogen， and reducing the time to flowering or emergence of the inflorescence of the plant. Claim 5: An isolated molecule characterized in that comprising one construct of nucleic acid which comprising one isolated polynucleotide that Includes one sequence of nucleic acid that is， to the less， 80 % identical to SEQ ID no: 3487， 1-24， 26-239， 467-917， 919-1973， 3481-3486， 3488-3504， 3506-3674， 3738 or 3739 and one heterologous promoter for directing the transcription of said sequence of nucleic acid in one host cell， where Said sequence of nucleic acid is capable of increasing the yield， biomass， growth rate of growth， vigor， content of oil， performance of the fiber， Quality of the fiber， tolerance to the abiotic stress and/or efficiency in the use of nitrogen of one plant. Claim 12: An isolated transformed plant cell of exogenously with the isolated molecule of the claim 5 or 6， characterized in that the plant cell is capable of regeneration in an entire plant.
