Fatty acids in seed oil from plants are essential for human nutrients and have been used for industrial purpose. The growing demands of seed oil as food resources and feedstocks for industrial uses have attempted to modify fatty acid composition and to increase oil content in transgenic plants. Howe...

식물 종자오일의 지방산은 어디에 사용되는가? | 식물 종자오일의 지방산은 인간에 필수 지방산을 공급하는 식용 및 생필품 생산에 필요한 다양한 산업원료로 사용된다. 식물 오일의 식용 및 산업용 적합성과 경제성을 극대화하기 위해 유전공학에 의한 종자오일의 양과 지방산 조성 변형을 위한 대사조절연구가 계속 진행되고 있다. | |
식물 오일은 한계점은 무엇인가? | 식물 오일의 식용 및 산업용 적합성과 경제성을 극대화하기 위해 유전공학에 의한 종자오일의 양과 지방산 조성 변형을 위한 대사조절연구가 계속 진행되고 있다. 하지만 식물에 일반적으로 존재하지 않는, 산업적으로 유용한 특이지방산의 합성과 종자오일로의 축적은 한계가 있음이 알려져 있다. 그 이유는 재배가 용이하며 생산성이 높은 오일식물의 acyltransferase가 특이지방산에 대한 기질특이성이 떨어지며 또한 특이지방산에 대한 세포막지질에서 종자오일로 전환시키는 편집기작 (editing mechanism)이 없기 때문으로 사료된다. | |
11개의 acyltransferase 유전자는 어떤 역할을 할 것으로 추정되는가? | 증진할 수 있는 기술이 개발될 수 있을 것으로 기대한다. 피마자오일의 주성분인 산업용 특이지방산인 리시놀레인 지방산을 오일식물에서 생산하기 위해 이에 관여할 것으로 추정되는 11개의 acyltransferase 유전자를 피마자 유전체 데이터베이스에서 존재함을 확인하였다. 이들 유전자들의 도입에 의해 형질전환 식물이 갖고 있지 않은 리시놀레인산에 대한 기질 특이성을 부여하여 종자오일 내의 특이지방산의 생산을 증가시킬 것으로 기대된다. |
