复合性状转基因植物安全性评价的研究进展

Research Progress on the Safety Assessment of Stacked Genetically Modified Plants

随着转基因技术的不断发展,转基因作物实现了产业化。目前,单性状的转基因作物无法满足农业发展的需求,而复合性状转基因作物拓宽了转基因作物的功能,提高了资源的利用率,满足了农民多元化需求,具有广阔的应用前景,是转基因植物发展的新方向。由于转基因技术有一定的风险,因此对转基因作物的安全性监管较为重要,对于复合性状转基因作物,不同国家的安全性评价制度却不尽相同。综述了不同国家对复合性状转基因作物的安全性评价体制,旨为我国复合性状作物提供监管依据。

With the development of transgenic technologies,genetically modified（GM）crops have been commercialized. Nowadays, the transgenic crops of single-trait are unable to meet the needs of agriculture,while the transgenic strategy of stacked-trait broadens the functions of GM crops and improves the utilization of resources,therefore meets the multiple needs of farmers,owns the broad application prospects,and is a new trend for the development of GM plants. Since transgenic technology may bring certain risks,it is critical to manage the safety of GM crops. For stacked-trait GM plants,different countries have declared different rules and safety assessment regulations to supervise the new-developed plants. In this paper,the safety assessment regulations to stacked-trait GM plants in different countries were reviewed, which may provide the reference for the supervision of the stacked-trait transgenic plants in China.
