PURPOSE: A BrCYS7 promoter which is specific to receptable is provided to specifically induce gene expression in a certain tissue, and to effectively produce a gene product. CONSTITUTION: A promoter contains a nucleic acid sequence in sequence number 1. The promoter contains a nucleic acid sequence having 70% or more of sequence homology with the nucleic acid in sequence number 1. An expression vector contains the promoter, and is a pPBrCYS7 vector. A cell is transformed with the expression vector, and is an Agrobacterium sp. microorganism or a plant cell. |
