The present invention relates to a Solanum lycopersicum histidine decarboxylase-2 (SlHD-2) gene-derived fruit-specific expression promoter, to a 5′ untranslated region (5′-UTR), to a (5′UTR), —specific expression vector comprising same, to a method for the fruit-specific expression of an exotic gene using the expression vector, to a plant transformed with the expression vector, and to a seed thereof. According to the present invention, a gene introduced from a transformed plant can be specifically expressed fruit tissue as compared to the widely used conventional Cauliflower mosaic virus-derived CaMV 35S promoter which induces the expression of an exotic gene in the whole tissue. Further, the present invention can be valuably used in the development of a transformed plant, which seeks to produce valuable substances from fruit.
