摘要
以乙酰辅酶A羧化酶(ACCase)为作用靶标的除草剂是高效、选择性的禾本科杂草除草剂,其在全球范围内的广泛、重复使用,导致了抗药性杂草的发生和发展。到目前为止,已经在30个国家有37种抗此类除草剂的杂草生物型。抗药性杂草严重威胁杂草治理和农业生产,由此引发的生态问题及粮食安全问题引起了广泛的关注。文章概述了ACCase抑制剂抗药性杂草的发生现状,从杂草ACCase突变、代谢解毒等几个方面综述了杂草抗ACCase抑制剂的抗性机制,以期为ACCase抑制剂抗性研究提供参考。最后讨论了阻止或延缓抗药性发生的杂草管理措施。
Hebicides targeting acetyl-CoA carboxylase（ACCase） are effective and selective graminicides.Their widespread and repeated application in worldwide resulted in occurrence and evolution of resistant weed species.There have been 37 weed biotypes resistant to ACCase herbicides in 30 countries by now.The herbicide resistant weeds threatted to weed management and crop production,and the consequences leading to biological damage and food safety caused extensive concern in the world.This review summarized the current status of ACCase-inhibiting herbicide resistant weeds and the major mechanisms of resistance involed in the ACCase mutations,metabolic detoxification and so on.In order to provide useful information and references for researches of ACCase-inhibiting herbicide resistance.Potential management strategy for preventing and delaying the herbicide resistance evolution of weeds was discussed in the end.
