Production of miraculin protein in suspension cell lines of transgenic rice using Agrobacterium

To produce the miraculin protein in suspension cultures, rice (Oryza sativa L.) was transformed with Agrobacterium tumefacience EHA105 containing the miraculin AB512278 gene. The cell suspension cultures were established using cell lines selected from transgenic rice callus. The integration of the miraculin gene into the rice chromosome was confirmed using genomic PCR analysis. In addition, RT-PCR analysis indicated that the miraculin gene is expressed in the selected suspension cell lines. Thus, the recombinant miraculin was expressed in the transgenic suspension cell line, HK-2. Therefore, we have successfully developed a HK-2 line that produces miraculin. These results demonstrate that transformed cell suspension cultures can be used to produce a taste-modifying protein such as miraculin.
