“…Varying levels of quizalofop resistance have previously been reported in H. glaucum , where the resistant populations were greater than 27‐fold resistant to the herbicide . Similarly, a high level of quizalofop resistance was observed in other grasses, such as Avena fatua L., Echinochloa crusgalli (L.) Beauv . and Setaria faberi Herrm …”

This study has documented APP-to-CHD herbicide cross-resistance, the first case of ACCase inhibitor resistance due to Ile-2041-Asn mutation, and characterised the resistance to ALS inhibitors in H. glaucum. Resistance to ACCase inhibitors is due to a target-site mutation. The reversal of SU resistance by malathion and susceptibility to sulfometuron suggests that non-target-site mechanisms confer resistance to ALS inhibitors. © 2016 Society of Chemical Industry.

Target-Site Point Mutations Conferring Resistance to ACCase-Inhibiting Herbicides in Smooth Barley (Hordeum glaucum) and Hare Barley (Hordeum leporinum)

Acetyl coenzyme A carboxylase (ACCase)-inhibiting herbicides affect fatty acid biosynthesis in plants and are widely used to control smooth and hare barley in dicot crops in Australia. Recently, growers have experienced difficulty in controlling smooth and hare barley with herbicides from this mode of action. Dose–response experiments conducted on five suspected resistant populations confirmed varying levels of resistance to quizalofop and haloxyfop. The level of resistance in these populations was greater than 27-fold to quizalofop and greater than 15-fold to haloxyfop. The quizalofop dose required to reduce shoot biomass by 50% (GR50) for the resistant populations varied from 52.6 to 111.9 g ha−1, and for haloxyfop from 26.5 to 71.3 g ha−1. Sequencing the CT domain of the ACCase gene from resistant plants of different populations confirmed the presence of previously known mutations Ile1781Leu and Gly2096Ala. Amino acid substitution at the 2096 position conferred a greater level of resistance to haloxyfop than the substitution at the 1781 position. This study documents the first known case of field-evolved target-site resistance to ACCase-inhibiting herbicides in Australian populations of smooth barley.

“…Plants of E. crusgalli resistant to quizalofop-p-ethyl had more activity of a GST when compared to the susceptible biotypes (Huan et al, 2011). In resistant biotypes of E. crus-galli, the gene EcGST1 that encodes a GST changed the expression level from 6 to 10-fold after aspersion of quinclorac herbicide (Li et al, 2013).…”

-Non-target-site resistance (NTSR) to herbicides mainly caused by enhanced degradation is highly problematic due to the occurrence of biotypes with multiple resistance and is a new challenge for weed management and herbicide use. Recently, enzymes associated with xenobiotic degradation especially cytochrome P450, GSTs and ABC transporters have been associated with the herbicide resistance in several weeds. This knowledge opens a new window to understand the evolution of NTSR. The aims of this review are to discuss the current knowledge of the gene regulation associated with the herbicide resistance caused by enhanced herbicide degradation and to analyze the main consequences of this problem for the adequate herbicide use and weed management. Multiple herbicide resistance caused by degradation enhancement occurs in Lolium rigidum, Alopecurus myosuroides, Echinochloa phyllopogon and in several other species. The level of herbicide resistance caused by degradation enhancement is affected by environmental factors in several cases, which difficult the resistance diagnostic and facilitate its distribution. The modern weed management should consider the characteristics of the herbicide degradation, since the simple rotation of herbicides mechanism of action might not be enough to prevent the herbicide resistance. The use of synergistic mixtures of herbicides and other enzyme inhibitors may contribute to prevent the evolution and spreading of NTSR weed herbicide resistance. Keywords: multiple resistance; cytochrome P450; detoxification; NTSR Resumo -A resistência a herbicidas causada por mecanismos não relacionados ao local de ação (NRLA), principalmente causada pelo incremento de metabolização, é altamente problemática devido à ocorrência de biótipos com resistência múltipla, e é um novo desafio para o manejo de plantas daninhas e utilização de herbicidas. Recentemente, enzimas associadas à degradação de xenobióticos, especialmente citocromo P450, GSTs e transportadores ABC, têm sido associadas à resistência a herbicidas em várias plantas daninhas. Os objetivos desta revisão são descrever o conhecimento atual da regulação gênica associada à resistência a herbicidas causada pelo incremento de metabolização e analisar as principais implicações deste problema para definir estratégias adequadas de manejo com o uso de herbicidas. A resistência múltipla a herbicidas causada pelo incremento da degradação ocorre em Lolium rigidum, Alopecurus myosuroides, Echinochloa phyllopogon e outras várias espécies. O nível de resistência a herbicidas causada pelo incremento de metabolização é afetado por fatores ambientais em vários casos, o que dificulta o diagnóstico da resistência e facilita sua distribuição. O manejo moderno de plantas daninhas deve considerar as características de degradação do herbicida, uma vez que a simples rotação de mecanismo de ação de herbicidas pode não ser suficiente para prevenir a ocorrência da resistência a estes produtos. A utilização de misturas sinergísticas de herbicidas e outros inibidores e...
