Monitoring of the Escape of Introduced Genes of Transgenic Oilseed Rapes Outside the Trial Site in a Confined Field Trial
pp.241-246
1. 본 연구에서는 GM 유채(Brassica napus)의 환경방출실험시의 안전관리를 위한 모니터링을 수행하였다.
2. 문헌조사를 통해 유채의 품종 순도 유지를 위한 격리거리와 교잡가능한 종을 확인함으로써 모니터링의 범위와 모니터링 대상 식물종을 결정하였다.
3. GM 유채의 격리포장으로부터 1.3 km 거리 범위 내에서 발견된 B. napus, B. juncea 및 B. oleracea를 대상으로 모니터링을 실시한 결과, 교잡을 통한 유전자의 유출은 발견되지 않았다.
One of the main concerns in field trials of GM crops is transgene escape from GM crops to conventional crops or weedy (wild) relatives via pollen dispersal. The management of field trials is therefore aimed at the detection and prevention of hybridization between GM crops and their closely related species around the field. This study monitored the escape of introduced genes of GM oilseed rapes (Brassica napus) outside the trial site during a small-scale field trial. First, a monitoring area (up to 1.3 km from the isolated field site) was determined according to recommended isolation distances for maintaining varietal purities of oilseed rapes. Then, target species (B. napus, B. juncea and B. oleracea) for monitoring were chosen using a literature search of plant species reproductively compatible with oilseed rapes. Hybrids between GM oilseed rapes and sexually compatible species were not detected and this result indicated that transgene escape outside the trial site did not occur during a field trial.
