作物抗除草剂的基因工程是国际上植物基因工程研究领域中的活跃中心之一。阿特拉津(Atrazine)是玉米生产中广泛使用的除草剂,对玉米无害,效果良好。但对与其间作套种的豆类或复种轮作的小麦、水稻等作物却造成了伤害。1983年国外就有人提出将杂草中的抗阿特拉津基因转侈到怍物中的设想,但迄今尚未取得实质性进展。国外研究表明,对阿特拉津的抗性是 Herbicide-resistant gene engineering is one of the active centers in the field of plant genetic engineering in the world. Atrazine is a widely used herbicide in corn production that is harmless to corn and works well. However, crops such as wheat and rice, interplanted with legumes or multiple crop rotation, have caused injury. In 1983, some people abroad put forward the idea of ​​destroying the gene of anti-atrazine in weeds to the dead, but so far no substantive progress has been made. Foreign studies show that resistance to atrazine is
