Abstract

Final regulatory steps for commercialization of transgenic crops are risk assessment and variety registration. The risk assessment of transgenic crops requires broad network of scientists, high cost and long term. Developers of transgenic crops, therefore, face to additional challenges to consider theoretical and strategic aspects on risk assessment. The general concept for risk assessment of genetically modified organisms was derived from chemical risk assessment. Due to the complexity of organisms, however, comparative approaches that are substantial equivalence and familarity have been developed. In practical view, the integration of risk assessment is more difficult than the evaluation of each risk factors involving gene flow, toxicity and allergenicity. Variety registration of transgenic crops requires the results of risk assessment compared with non-GM crops and agronomic data analyzed with standard varieties. For economic and fast commercialization, risk assessment process should combined with condition of cultivation test for variety registration.

형질전환작물 상업화의 최종 규제단계는 위해성심사와 품종출원이다. 위해성심사를 위한 형질전환작물의 위해성 평가는 광범위한 과학자 네트워크, 고비용과 오랜 기간을 필요로 한다. 따라서 형질전환작물 개발자는 우수한 형질의 개발 이외에 위해성평가에 대한 이론적 및 전략적 측면을 부가적으로 고려해야 한다. 유전자변형생물체의 위해성평가에 대한 일반적인 개념은 화학물 위해성평가로부터 유래하였다. 그러나 생물체가 가지는 복잡성 때문에 실질적동등성과 친숙성으로 대표되는 비교접근 방법이 개발되어 왔다. 실제적인 측면에서 통합적인 위해성평가는 유전자이동성, 독성과 알레르기와 같은 개별 위해성평가보다 더 어렵다. 형질전환 계통의 품종출원을 위해서는 위해성평가 단계에서부터 품종보호요건을 고려한 평가자료 생산과 위해성 심사 승인 계통을 이용한 다양한 LMO 품종 육종전략이 필요하다.
