如日本烟草公司开辟了用于防除草坪杂草早熟禾的细菌除草剂（Xantho monascapestris）;俄罗期科学院则开辟了用于防治蚜虫和红蜘蛛等害虫的细菌性杀虫剂双 毒杆菌。

他们团队用利用锌指结构以IPK1基因为目标，另外添加可以中断此基因同时赋予植物抗除草剂性质的细菌DNA序列。
The team used zinc fingers that specifically target the IPK1 gene and then added bacterial DNA that would disrupt the gene while at the same time conferring herbicide resistance to the plant.
两次连击奏效了：团队报道说，细菌基因一次性中断IPK1基因的几率达到3%—100%，同时植物也具有抗除草剂特性。
The double shot worked: the bacterial gene disrupted the IPK1 gene between 3% and 100% of the time and also made the plants resistant to herbicides, the team reports.
举例说，抗草甘膦转基因大豆中的抗除草剂基因，由一种植物病毒、两种不同的土壤细菌，以及一种矮牵牛花植物的基因组合而成。
For example, the herbicide-resistant gene in GM RR soy was pieced together from a plant virus, two different soil bacteria, and a petunia plant.
