把菠菜基因植入猪的体内能使肉和蔬菜在活着的家畜身上完美地结合起来,这是日本的研究人员实现的。做这个实验并不容易,研究人员把菠菜基因移植到受精的猪胚胎中,然后把胚胎植入普通猪的子宫中,这些普通猪产下经过基因改造的猪仔,成活率大约只有1％。经过基因改造的猪体内大约有20％的饱和脂肪酸被转化成不饱和亚麻酸。 Implanting the spinach gene into the pig’s body enables the perfect combination of meat and vegetables in living livestock, which is achieved by Japanese researchers. It is not easy to do this experiment. The researchers transplanted the spinach gene into fertilized pig embryos and then implanted the embryos in the uterus of ordinary pigs. These ordinary pigs produced genetically modified piglets with a survival rate of only about 1%. About 20% of saturated fatty acids in genetically modified pigs are converted to unsaturated linolenic acid.
