在将来的某一天,使用树木制浆造纸所需耗费的能量将远远少于现在,这要感谢美国科学家利用一种来自中药材的基因对树木进行的基因改造。此项研究由美国能源部大湖生物能研究中心的生物化学家约翰·拉尔夫及其同事进行。拉尔夫表示这种基因能够改变木质素(起到强化细胞壁的作用)使其更容易被工业化学品分解。约翰·拉尔夫及其同事在中药当归的根部找到一种天然 One day in the future, the amount of energy used to pulp paper using trees will be far less than it is now, thanks to the genetic modification of trees by a U.S. scientist using a gene derived from Chinese herbal medicines. The study was conducted by biochemist John Ralph and his colleagues at the US Department of Energy’s Great Lakes Bio-Energy Research Center. Ralf said the gene can change the lignin (to strengthen the cell wall) to make it more easily broken down by industrial chemicals. John Ralph and colleagues found a natural presence at the roots of Chinese angelica
