最近,美国佐治亚州大学的研究人员利用基因重组技术,培育出一种可以清除重金属汞等严重污染的白杨树。 研究人员从抗重金属细菌里提取出基因,对其进行改造后再把它插入白杨树的遗传编码里。试验表明,这种转基因杨树抗汞的能力提高了10倍。 这种杨树清理重金属污染的原理非常简 Recently, researchers at the University of Georgia in the United States used gene recombination techniques to develop poplar trees that remove heavy pollution such as heavy metal mercury. Researchers extracted genes from heavy metal-resistant bacteria, rebuilt them and inserted them in the poplar genetic code. Experiments show that this transgenic poplar tree to improve the ability of mercury 10 times. The principle of poplar cleaning heavy metal pollution is very simple
