遗传工程像“魔术师”一样。它最拿手,最通常采用的办法是,把一种生物的细胞与另一种生物的细胞完全融合,让两个细胞内的物质,包括基因在内,全部融汇在一起来培养,选择出优良植株。例如苏联科学家将马铃薯与蕃茄的细胞加以融合,终于培育出能在地上部位长蕃茄、地下部位长马铃薯的新杂种。豇豆与烟草的杂种已在英国产生,烟草因为得到了豇豆的胰蛋白酶抑制剂,从而使烟 Genetically engineered like “magician”. It is the most adept, the most commonly used approach is to fully integrate the cells of one organism with the cells of another organism, so that the two cells, including genes, including all, together to cultivate, select Fine plant. For example, Soviet scientists fused cells of potatoes and tomatoes and finally bred new hybrids that grew tomatoes on the ground and long potatoes in the ground. Vignaines and tobacco hybrids have been produced in the United Kingdom, because of the cow’s bean trypsin inhibitor, so that the smoke
