摘要

Polipeptu00ecdio isolated, polinucleotu00ecdeo insulated tape of expression alone, method for obtenu00e7u00e1o of a plant or plant part used, methods of modulau00e7u00e1o of nu00fdvel of polipeptu00ecdios DOF in plants or parts of plants, to increase the use efficiency of nitrogen in a pl Anta, to increase productivity in a plant, to improve the response of plant stress.Methods and compositions are provided to improve the efficiency of the use of nitrogen in plants and parts of plants, to increase carbon sequestration in a plant or a part of the plant, to increase the productivity of grain or biomass production of the plant, and / or increase the tolerance to stress p Or the part of the plant.The compositions and methods of the invention modulate these various phenotypes through the control of the level of at least one DOF polypeptide (for connection to the DNA, with a "finger", English "DNA binding with one finger") presenting at least one domain or biologically active variant of a Or fragment of a Dof domain.In addition, the present invention relates to a method for obtaining a plant or plant part used, comprising transforming a plant with a cell polinucleotu00eddeo operationally linked to a promoter that drives expression in plants.In the polinucleotu00eddeo comprises a sequ00fau00eancia nucleotides or the transformation of a plant cell or plant part processed with a tape of expression, the cultivation of the plant cell under conditions of growth and regeneration of the plant transformad A.
