초록

유전자변형 작물이 절지동물에 미칠 수 있는 잠재적인 부정적 영향은 유전자변형 작물의 주요한 환경위해성의 하나로 여겨지고 있다. 본 연구에서는 PPO (protoporphyrinogen oxidase) 저해 제초제 내성 유전자변형 벼가 절지동물에 미칠 수 있는 영향을 평가하기 위하여 절지동물의 다양성과 군집구조를 조사하였다. 절지동물은 야외포장에서 벼의 생육기간 동안 황색점착트랩을 이용하여 채집하였다. 유전자변형 벼는 채집된 절지동물군집의 다양도 지수에 유의한 영향을 주지 않았다. 또한 다변량분석(PerMANOVA, NMDS) 결과에서도 절지동물군집 구조는 채집시기에 따라 달랐지만 벼의 유전형(유전자변형 또는 비변형)에 의해 영향을 받지 않았다.
