1946年,科学家首次发现DNA可以在生物间转运。1983年,世界上第一例转基因植物——含有抗生素药类抗体的烟草在美国成功培植。1992年,中国首先在大田生产上种植抗黄瓜花叶病毒转基因烟草,成为世界上第一个商品化种植转基因作物的国家。但经过几十年的发展,转基因作物并没有高歌猛进,相反, In 1946, scientists first discovered that DNA can be transported between organisms. In 1983, the world’s first transgenic plant - containing antibiotic drug-resistant tobacco in the United States successfully cultivated. In 1992, China first planted genetically modified tobacco against cucumber mosaic virus in field production and became the first country in the world to commercially produce genetically modified crops. However, after decades of development, genetically modified crops are not triumphantly, on the contrary,
