植物转基因技术是指利用重组技术、细胞DNA培养技术或种质系统转化技术将目的基因导入植物基因组,并能在后代中稳定遗传,同时赋予植物新的农艺性状的技术。自1996年商业化种植以来,转基因玉米迅速在全球范围内商业化。到2010年全球种植转基因作物的国家有29个,其中共有16个国家种植商业化转基因玉米,种植面积已达到4680万hm2。1目前应用的转基因技术目前应用较多和成熟的转基因技术主要有农杆菌介导法、基因枪法、花粉管通道法、PEG介导法、超声波介导法、电击法、子房注射法等,还有近几年才
Plant genetically modified technology refers to the technology of using recombinant technology, cell DNA cultivation technology or germplasm system transformation technology to transfer the target gene into the genome of a plant and to inherit stably in the offspring while giving the plant new agronomic traits. Since its commercial planting in 1996, GM maize has rapidly become commercially available worldwide. There are 29 countries that planted GM crops worldwide by 2010, of which 16 countries planted commercial GM maize and the acreage has reached 46.8 million hm2. 1 Currently applied GM technologies Currently, more and more mature GM technologies are mainly used in agriculture Bacillus mediated method, gene gun method, pollen tube channel method, PEG mediated method, ultrasound-mediated method, electric shock method, ovary injection, etc., in recent years
