目前人们对转基因作物的安全性评价焦点集中在释放的生态安全性、物种的遗传安全性和食物的消费安全性三个方面。对转基因作物安全性的检测目前还没有一套快速、准确、灵敏的方法,通常可用酶分析法和组织化学定位法鉴定标记基因,用PCR扩增法鉴定目的基因。 At present, the safety evaluation of genetically modified crops is focused on three aspects: the ecological safety of release, the genetic safety of species and the consumption safety of food. At present, there is not a fast, accurate and sensitive method to detect the safety of genetically modified crops. Generally, enzyme markers and histochemical methods can be used to identify the marker genes and the target genes can be identified by PCR amplification.
