초록

In recent years, there has been increasing concerns in gene flow from GM crops to wild or weedy relatives as a potential risk in the commercialization of GM crops. To access the possibility of the environmental impacts by GM rice, small-scale experiments of gene transfer were carried out. Herbicide and drought stress resistant GM rice and non-GM rice Nakdongbyeo, wild rice Oryza nivara, and weedy rice Sharebyeo were used for artificial pollination experiments and bar gene was used as a tractable marker after pollination. The harvested putative hybrid seeds after artificial pollination were germinated and true hybrid plants were selected by basta treatment. The hybrid plants were verified again by PCR amplification of bar and trehalose-6-phosphate phosphatase (TPP) genes and RAPD PCR analysis.

최근 GMO 작물의 재배, 생산이 날로 늘어나며 GMO 작물이 환경에 미칠 수 있는 많은 가능성들이 대두되고 있다. 특히 GMO 작물과 야생종과의 자연교잡에 의한 유전자 전이로, 잡초화의 문제점이 제기되며 생태계의 변화 및 파괴의 위험성이 우려되고 있다. 본 실험에서는 GM벼와 야생 및 근연종 사이의 교잡가능성 및 유전자 전이율을 조사하기 위한 유전자 이동의 분석 체계를 확립하고자 하였다. 벼의 개화시기에 GM벼와 야생 및 근연종 간의 인공교배 후 수확한 교잡 추정 종자를 발아시켜서 제초제를 처리하여 교잡종자를 선별하였다. 또한 GM 벼 및 야생 근연종벼들 간의 RAPD PCR 분석을 통해 선별한 marker를 사용하여 낙동 교잡벼와 샤레 교잡벼가 GM 벼와 교배된 식물체임을 확인하였다. PCR 분석을 수행한 결과 GM벼에서 도입된 trehalose-6-phosphate phosphatase (TPP) 유전자와 선별marker로 사용된 bar유전자가 GM벼 뿐만 아니라 샤레 교잡벼에도 존재하였으며, 결과적으로 GM벼의 bar 및 tpp 유전자가 잡초성벼인 샤레 교잡벼에 전이되었음을 검증할 수 있었다.
