초록

본 실험에서는 식물의 유용유전자를 개발하여 그 발현양상을 확인하기 위하여 효모를 이용하면 그 발현양상을 비교적 빠르게 확인할 수 있는 미토콘드리아 형질전환 방법을 규명하였다. 또한 미토콘드리아(mt)에 관련된 유전자를 TPI promoter를 가진 plasmid에 재조합한 후 효모에 형질전환하여 mt에서 그 유전자의 특성이 발현 되는 것을 확인하였다. 따라서 본 연구의 결과로 mt에 관련된 유전자를 식물의 조직에 형질전환 하여 1개 이상의 유전자가 식물의 mt에 삽입되어 그 유전자의 특성이 발현되는데 이용되어 질수 있을 것이라 생각된다.

Yeast mitochondrial transformation has been confirmed by cell death and CFP expression (CDF: cell death factor gene). Expression vector containing CDF and CFP driven by one TPI (Triose-phosphate isomerase) promoter (called artificial operon type) was bombarded to Yeast. Interestingly, yeast cells were progressively deformed into unusual shapes and lysed inner cytoplasm resulting in ell death after all after bombarding with expression vector (CDC and GFP). Since there is no report about more than one gene expression simultaneously in a single mitochondria, this report is very important to novel type of eukaryotic gene expression. Successful yeast cell transformation in this report implies possible eukaryotic mitochodrial transformation including plants and animals and moreover two or more gene expression which can be excellent applicable protocols to pharmaceutical field including antibody production.
