一种断裂基因阻障的新技术已经产生——即用电损伤植物细胞的“电穿击法”.方法是在细胞膜上穿个小孔洞,使遗传学家能够把无血缘关系的物种遗传物质注射到农作物细胞中去,从而达到创造出高营养玉米、耐涝的麦子或抗病的谷物的目的。这种新技术正在美国斯坦福大学研究中。1985年,分子生物学家迈克尔·弗罗姆和植物生理学家弗吉尼亚·沃尔博特使用“电穿击法”转移一新基因进入玉米细胞,结果令人吃惊.这一技术比其他已知的方
A new technique to break gene barriers has been created - the “electroporation” of using electricity to injure plant cells by making tiny holes in the cell membrane that allow geneticists to link unrelated species’ genetic material Injected into crop cells for the purpose of creating highly nutritious corn, waterlogged wheat or disease-resistant cereals. This new technology is being studied at Stanford University in the United States. In 1985, molecular biologist Michael Frome and plant physiologist Virginia Walbott used the “electroporation method” to transfer a new gene into corn cells, with surprising results. This technique is superior to other known square
