生物技术衍生的抗除草剂作物的出现使许多国家的耕作方式发生了革命性变化。简便、高效、无害环境和有利可图的杂草控制方法已被作物生产者迅速采用，他们重视与生物技术衍生的杂草管理性状相关的益处。但是，对目前与抗除草剂作物一起使用的除草剂具有耐受性或抗性的几种麻烦杂草的种群迅速增加，可能意味着这些经济上重要的杂草管理性状的有效寿命将被缩短。我们描述了对麦草畏（一种广泛使用的、廉价的、对环境安全的除草剂）具有抗性的大豆和其他阔叶植物物种的发展。麦草畏抗性技术将增强现有的除草剂抗性技术并延长其有效寿命。核和叶绿体编码的麦草畏抗性基因，影响除草剂抗性性状的效力和预期的持久性的属性进行检查。
The advent of biotechnology-derived, herbicide-resistant crops has revolutionized farming practices in many countries. Facile, highly effective, environmentally sound, and profitable weed control methods have been rapidly adopted by crop producers who value the benefits associated with biotechnology-derived weed management traits. But a rapid rise in the populations of several troublesome weeds that are tolerant or resistant to herbicides currently used in conjunction with herbicide-resistant crops may signify that the useful lifetime of these economically important weed management traits will be cut short. We describe the development of soybean and other broadleaf plant species resistant to dicamba, a widely used, inexpensive, and environmentally safe herbicide. The dicamba resistance technology will augment current herbicide resistance technologies and extend their effective lifetime. Attributes of both nuclear- and chloroplast-encoded dicamba resistance genes that affect the potency and expected durability of the herbicide resistance trait are examined.
