Vector containing gene encoding specific promoter and specific protein, transformed plant introduced with the vector, and method for improving polyisoprenoid production by introducing the vector into the plant
Provided is a vector capable of improving polyisoprenoid production through the introduction of the vector into a plant using gene recombination techniques. A vector comprising: a promoter of a gene encoding Hevein 2.1; and a gene encoding a protein involved in polyisoprenoid biosynthesis, the gene being functionally linked to the promoter.
