With intensive and extensive using herbicides,the level of weed resistance was increased,new resistance mechanisms are constantly being discovered.Adcances on the mechanisms of target-site resistance(TSR)and non-target-site resistance(NTSR)in recent ten years were summarized in this paper.The progress of TSR mainly included new resistance mutation in herbicide target enzymes of acetolactate synthase,acetyl-CoA carboxylase and 5-enolpyruvylshikimate-3-phosphatesynthase,as well as various resistance mutations occurring in target enzyme and multiple mutated target isozymes that resisting stronger herbicide selection.In addition,the roles of NTSR in glyphosate resistance of cytochrome P450(CYP81),aldo-keto reductase and ABC transporter protein(EcABCC8)were also described in detail.This paper is beneficial for understanding the molecular mechanisms and evolu-tionary laws of weed resistance from more profound and comprehensive perspective,and also provides inspriration for scientifically using herbicides and designing new herbicides with new mode of action.
