摘要:
目前，杂草抗药性已经成为制约农作物生产的主要因素，杂草抗药性机制分为靶标抗性及非靶标抗性。靶标抗性包括靶标基因突变和靶标基因过量表达；非靶标抗性是由杂草对除草剂的吸收传导减弱、屏蔽隔离作用以及杂草对除草剂的代谢解毒能力增强等原因引起，其中以增强杂草对除草剂的代谢为主。为了应对杂草抗性的发展，科学治理抗性杂草，通过简要介绍乙酰羟基酸合成酶（AHAS）结构及杂草抗性机制，包括杂草抗性情况、靶标抗性、突变对AHAS结构及功能的影响、非靶标抗性机制，并对抗性杂草的适合度及其影响因素等相关研究进展进行综述，进一步提出应对抗性杂草治理的建议，以减少对农药的依赖，保障农业的可持续发展。
Abstract:
The weed resistance has become the major factor restricting crop production, and the mechanism of weed resistance is divided into target resistance (TSR) and non-target resistance (NTSR). Target resistance includes target gene mutation and target gene overexpression. Non-target resistance is caused by the reduced absorption and conduction of weed to herbicide, the shielding and isolation, and the enhanced detoxification ability of weed to herbicide, in which the enhancement of weed metabolism is the primary reason. In order to cope with the development of weed resistance and scientifically control resistant weeds, the structure of acetohydroxyacid synthase (AHAS) and weed resistance mechanism were briefly introduced, including weed resistance, target resistance, effects of mutation on structure and function, non-target resistance mechanism, and relevant research progress on the suitability and influencing factors of resistant weeds. In order to reduce the dependence on pesticides and ensure the sustainable development of agriculture, some suggestions on the management of resistant weeds were put forward.
