摘要：
The present invention refers to a promoter and/or specific regulatory regions for the expression of genes of interest in roots. The invention further describes DNA constructs containing the polynucleotide of the invention operatively linked to a heterologous and/endogenous gene. Besides, the invention refers to the use of these constructions in the form of expression vectors, recombinant vectors and in plants, plant cells or transgenic protoplasts. The invention further describes a method employing such constructs containing the polynucleotide of the invention for the production of plants, plant cells or transgenic protoplasts. Thus, the expression of the transgene only in the part of interest enables the accumulation of the exogenous transcript only in the root, favoring the implementation of strategies that aim at increasing the aggregated value, the generation of cultivars more adapted to environmental stress, to pathogens and pests, agrochemicals, besides plants with a high nutritional value and high therapeutic value. In addition to these advantages, the present invention is a new alternative to expression systems in vegetable organisms and may be used for generating new cultivars and improvement programs.
