“…GM작물의 비표적 생물체에 대한 영향평가는 국외에서는 해충저항성 옥수수(MON810)과 해충저항성 Bt벼 (Huahui 1)에 대한 물벼룩(Daphnia magna)의 생존과 번식률 등에 대한 실험이 보고되었으며 (Thomas et al, 2010;Li et al, 2014), 국내에서도 국내 개발 GM작물의 실용화와 국외 GM작물 수입량 증가에 따른 수송로 및 경작지 주변의 환경지표 생물종 설정과 이에 대한 영향 평가의 필요성이 요구되고 있으며, 국내 개발된 해충저항성 Bt벼, 비타민 A 강화벼, 레스베라트롤 생합성 GM벼 등에서 보고되고 있으며, 특히 벼는 담수조건에 생육하므로 수서생물인 미꾸리 (Misgurnus anguillicaudatus), 잉어(Cyprinus carpio), 물벼룩 등에 대한 평가가 수행되고 있다 (Oh et al, 2012;Moon et al, 2013;Oh et al, 2014b).

A drought-tolerant transgenic rice (Agb0103) was developed using a pepper methionine sulfoxide reductase (CaMsrB2) under the control of rice Rab21 promoter with a selection marker, the phosphinothricin acetyltransferase (PAT) gene. Commercialization of genetically modified (GM) crops will require the evaluation of risks associated with the release of GM crops. With the potential problems associated to GM crops safety testing, the investigation of their effects on non-target organisms is necessary for environmental risk research. This study was carried out to assess acute toxicity of a GM crop using the water flea (Daphnia magna) for non-target organism risk evaluation. The effect of acute toxicity on Daphnia magna of Agb0103 rice and a non-GM rice, Ilmibyeo, were investigated at different concentrations (0, 625, 1,250, 2,500, 5,000, and 10,000 mg/L). The Agb0103 rice used for the test was confirmed to express the CaMsrB2/PAT gene by the PCR and ELISA. Daphnia magna feeding tests showed no significant differences in cumulative immobility or abnormal response with either Agb0103 rice or non-GM rice. The 48hr-EC 50 values showed no difference between Agb0103 rice (2243 mg/L) and non-GM rice (2694 mg/L). These results suggest that there is no significant difference in toxicity to Daphnia magna between Agb0103 rice and its non-GM counterpart.
