ACCase mutations in Avena sterilis populations and their impact on plant fitness

Pesticide Biochemistry and Physiology, 2015
Avena sterilis (sterile oat) populations originating from wheat-growing regions of Greece, developed resistance to fenoxaprop, clodinafop and other herbicides. The partial ACCase gene sequence revealed six point mutations (Ile-1781-Leu, Trp-1999-Cys, Trp-2027-Cys, Ile-2041-Asn, Asp-2078-Gly, and Cys-2088-Arg) in 24 out of the 26 resistant (R ...

Molecular Genotyping of Herbicide Resistance in P. minor: ACCase Resistance

Applied Biochemistry and Biotechnology, 2014
Little seed canary grass (Phalaris minor Retz.) populations resistant to herbicides that inhibit acetyl-CoA carboxylase (ACCase) represent an increasingly important weed control problem in northern India. The objective of this study was to develop DNA-based markers to differentiate herbicide-resistant and herbicide-susceptible population of P.

A novel ACCase Trp-1999-Gly mutation confers resistance to ACCase-inhibiting herbicides in Chinese sprangletop (Leptochloa chinensis)

Plant Physiology and Biochemistry
Chinese sprangletop (Leptochloa chinensis (L.) Nees) is among the most economically damaging and disruptive weeds found in rice fields across China, and it exhibits a high degree of cyhalofop-butyl resistance for the past few years. Here, a suspected cyhalofop-butyl-resistant population HFCH5 (R) was collected from a rice field and analyzed to explore ...

Molecular basis for resistance to ACCase-inhibiting herbicides in Pseudosclerochloa kengiana populations

Pesticide Biochemistry and Physiology, 2015
Pseudosclerochloa kengiana is a troublesome annual grass weed of wheat fields in the rice-wheat double cropping areas in China. Resistance has evolved in P. kengiana under continuously selective pressure of ACCase-inhibiting herbicides. Whole-plant experiments showed that two suspected resistant populations 12-SD-12 and 12-SD-13 were highly resistant ...

Lolium rigidum, a Pool of Resistance Mechanisms to ACCase Inhibitor Herbicides

Journal of Agricultural and Food Chemistry, 2005
Three diclofop-methyl (DM) resistant biotypes of Lolium rigidum (R1, R2, and R3) were found in different winter wheat fields in Spain, continuously treated with DM, DM + chlortoluron, or DM + isoproturon. Herbicide rates that inhibited shoot growth by 50% (ED50) were determined for DM.

A Rare Ile-2041-Thr Mutation in the ACCase Gene Confers Resistance to ACCase-inhibiting Herbicides in Shortawn Foxtail (Alopecurus aequalis)

Weed Science, 2017
Understanding the mechanism of herbicide resistance is fundamental for designing sustainable weed control strategies and exploiting herbicides rationally. Shortawn foxtail is a problem grass weed infesting several important crops in China. The repeated use of acetyl-CoA carboxylase (ACCase)-inhibiting herbicides has resulted in herbicide resistance in ...

Basis of ACCase and ALS inhibitor resistance in Hordeum glaucum Steud

Pest Management Science, 2017
AbstractBACKGROUNDAcetyl coenzyme‐A carboxylase (ACCase) and/or acetolactate synthase (ALS) inhibitor resistance has been identified by herbicide resistance screening in eight populations obtained from cropping regions of South Australia. This study aimed to quantify the level of resistance and characterise the molecular basis of resistance to ACCase ...

Mapping risk areas for resistance to ACCase inhibitor herbicides in Manitoba

Canadian Journal of Plant Science, 1997
Since 1976, seven acetyl coenzyme-A carboxylase (ACCase) inhibitors (referred to as Group 1 herbicides) have been registered in western Canada for wild oat (Avena fatua L.) and green foxtail (Setaria viridis L.) control. In 1990, Group 1 resistant wild oat populations were identified from fields in Manitoba which had been repeatedly sprayed with these

Field and producer survey of ACCase resistant wild oat in Manitoba

Canadian Journal of Plant Science, 1997
In a previous study, 729 townships in Manitoba were differentiated as being at low, medium, or high risk of evolving wild oat resistant to Group 1 herbicides based on herbicide use histories from 1981 to 1993. In the present study, 16 townships representing the three risk categories were surveyed in 1994 in order to determine the percentage of ...
