近年来,植物基因工程的一些技术关键已有所突破,外源基因或DNA可以导入植物,使之整合、表达普遗传。利用Ti质粒的T-DNA系统,已应用于双子叶植物得到成功,但还没有做到实用价值的基因转移。我国自1978年开始,中国科学院上海生化所和遗传所、中国农科院作物所、广西农学院、江苏农科院经济作物所及沈阳农学院遗 In recent years, some key technological breakthroughs in plant genetic engineering have been achieved. Exogenous genes or DNA can be introduced into plants to integrate and express the genetics. T-DNA systems that utilize the Ti plasmid have been used successfully in dicotyledons but have not yet been of practical value for gene transfer.
