| Abstract | 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. 벼(Oryza sativa L.)에서 세포 현탁 배양을 통한 miraculin 단백질의 생산을 위해 miraculin 유전자(AB512278)가 도입된 Agrobacterium tumefacience EHA105를 매개로 벼 캘러스에 형질전환하였다. 현탁배양세포주는 형질전환 캘러스를 이용하여 몇번의 선발과정 및 계대배양을 통해 선발하였고, 게놈 PCR 분석을 통해 miraculin 유전자가 벼 염색체에 안정적으로 도입된 것을 확인하였다. 또한, RT-PCR 분석을 통해 형질전환 세포주에서 도입된 miraculin 유전자가 과발현 되었다. 재조합 miraculin은 형질전환 현탁배양 HK-2 세포주에서 가장 높게 발현되어 total soluble protein (TSP) 대비 2.0%를 보였다. 이러한 결과는 형질전환 현탁세포배양이 miraculin과 같은 미각 수식 단백질의 대량생산 시스템을 구축하는데 이용 가능 할 것으로 사료된다. |
