1987年,美国加利福尼亚和威斯康星州的育种专家在杨树抗除草剂育种方面取得了突破性进展。他们设计并合成出一个改良的T—DNA质粒,通过致瘤农杆菌输入受体,采用组培技术获得这一成果。文中还介绍了树木基因工程的一般原理。
Genetic engineering is a comprehensive technological field of biology,developed in the 1970's. Since 80's with its rapid development a wideapplication achieved in industry, agriculture and medicine. However it istoo difficult to be used in forestry, because large size and long life-spanof tree are limiting factors to use gene manipulation. Furthermore, noappropriate vector was known to integrate a purpose gene to it and thenbe transferred to the cell of a tree. In recent years technology of tissueculture ha...
