黄永芬教授和汪清胤研究员等人，从1990年开始了“番茄转基因育种”的研究。他们发现，生活在寒温带的一种名叫“美洲拟蝶”的冷水鱼，能产生大量的抗冻蛋白。于是，科研人员们将从中提取出的抗冻基因，在番茄开花时注人它的花粉管，得到基因变异的种子。再对新育出的植株用分 Professor Huang Yongfen and researcher Wang Qingyin and others, from 1990 on the “tomato genetically modified breeding” research. They found that a kind of cold water fish called “American butterfly” living in the frigid temperate zone, can produce a lot of antifreeze protein. So, researchers will extract the antifreeze gene, when the tomato flowering its pollen tube, get genetically modified seeds. Then use the newly-grown plants points
