Abstract

The cultivation area and use of genetically modified (GM) crops have been increased continuously over the world. Seed distribution and transgenes to environmental ecosystem is one of the most important factors in risk assessment and risk management of GM crop. Safe management for the development and commercialization of GM crops is required according to The Act on Transboundary Movements of Living Modified Organisms,etc (LMO Act) in Korea. This study was conducted to setup the environmental monitoring system of GM zoysiagrass (event JG21 and JG21-MS). The monitoring was performed in 4 GMO confined fields, Sungwhan, Ochang, Jeju University and Jeju Namwon. In the result of monitoring, we could not found any gene flow and distribution of GM zoysiagrass in the 3 fields, but one spill of JG21 was found in the Namwon field in 2012. These results suggest that continuous monitoring is necessary to detect the occurrence of GM zoysiagrass for preventing genetic contamination in natural environment.

유전자변형(genetically modified, GM)작물의 종자 및 꽃가루를 통한 환경 생태계로의 확산은 안전성평가와 안전관리에 있어 매우 중요한 요소이며, 국내에서는 LMO법에 따라 GM 작물의 개발 및 생산 등에 대한 안전관리와 GM 작물의 상업화를 위한 환경모니터링에 대한 방법, 기간, 빈도 등에 대한 계획을 요구하고 있다. 본 연구는 제초제저항성 들잔디(zoysiagrass)의 야외환경모니터링을 수행을 통한 환경모니터링 시스템 기반 구축을 위해 수행되었다. 연구에 사용된 GM 들잔디는 제초제저항 형질의 JG21과 JG21에 방사능처리로 웅성불임을 유도한 JG21-MS 등 2개의 이벤트를 이용하였다. 환경모니터링은 충남 성환, 충북 오창, 제주대 및 제주 납원읍 등 4개 격리포장 주변에서 2011년부터 2013년까지 종자 및 영양번식체에 의한 산포 조사와 화분에 의한 유전자이동에 대해 수행되었다. 모니터링 수행 결과 3개 지역에서 유전자이동 및 산포가 발견되지 않았으나, 2012년 제주 남원읍 지역 조사에서 격리포장 주변 2 m 부근에서 JG21 들잔디 1개체의 유출이 발견되어 보고 및 안전관리 조치를 수행하였다. 본 연구에서 사용된 GM 들잔디의 검출 방법과 환경모니터링 기법들은 GM 들잔디 개발을 위한 포장시험 연구와 상업화 후 환경모니터링을 위한 기초자료로 활용될 수 있을 것으로 기대한다.
