A novel mutation Asp-2078-Glu in ACCase confers resistance to ACCase herbicides in barnyardgrass (Echinochloa crus-galli)

Pesticide Biochemistry and Physiology, 2020
Multiple-herbicide resistance (MHR) in barnyardgrass (Echinochloa crus-galli) is a threat to rice production. The Ala-205-Val mutation in acetolactate synthase (ALS) conferred resistance to several ALS inhibitors in the E. crus-galli population AXXZ-2; consequently, ALS-inhibitors were unable to control this noxious weed species.

Cross-resistance patterns to ACCase-inhibitors in American sloughgrass (Beckmannia syzigachne Steud.) homozygous for specific ACCase mutations

Pesticide Biochemistry and Physiology, 2016
American sloughgrass is a troublesome annual grass weed in winter wheat field rotated with rice in China. The overreliance on acetyl-coenzyme A carboxylase (ACCase) inhibiting herbicides has resulted in resistance evolution in this weed. In this study, the cross-resistance patterns to fenoxaprop-p-ethyl, clodinafop-propargyl, fluazifop-p-butyl ...

Synonymous mutation gene design to overexpress ACCase in creeping bentgrass to obtain resistance to ACCase-inhibiting herbicides

Transgenic Research, 2016
Overexpression of a native gene can cause expression of both introduced and native genes to be silenced by posttranscriptional gene silencing (PTGS) mechanisms. PTGS mechanisms rely on sequence identity between the transgene and native genes; therefore, designing genes with mutations that do not cause amino acid changes, known as synonymous mutations ...

Allelic variation of the ACCase gene and response to ACCase‐inhibiting herbicides in pinoxaden‐resistant Lolium spp.

Pest Management Science, 2011
AbstractBACKGROUND: The repeated use of acetyl‐coenzyme A carboxylase (ACCase) inhibiting herbicides to control grass weeds has selected for resistance in Lolium spp. populations in Italy. The efficacy of pinoxaden, a recently marketed phenylpyrazoline herbicide, is of concern where resistance to ACCase inhibitors has already been ascertained.

Use of Resistant ACCase Mutants To Screen for Novel Inhibitors against Resistant and Susceptible Forms of ACCase from Grass Weeds

Journal of Agricultural and Food Chemistry, 2004
The aryloxyphenoxypropionic acid (AOPP) and cyclohexanedione (CHD) herbicides inhibit the first committed enzyme in fatty acid biosynthesis, acetyl CoA carboxylase (ACCase). The frequent use of AOPP and CHD herbicides has resulted in the development of resistance to these herbicides in many grass weed species.

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.

Characterisation and management of Phalaris paradoxa resistant to ACCase-inhibitors

Crop Protection, 2011
Phalaris paradoxa is a competitive grass commonly found in durum wheat crops of central and southern Italy. Among the 85 populations screened from 1998 to 2008 for resistance to ACCase-inhibitors and graminicide sulfonylureas, 17 resulted as being resistant to at least one ACCase inhibitor while none of the populations showed resistance to ...

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 ...

Johnsongrass (Sorghum Halepense) Pollen Expresses Accase Target-site Resistance

Weed Technology, 2007
Three studies were conducted to develop pollen tests for the screening of acetyl coenzyme-A carboxylase (ACCase) target-site resistance in a biotype of johnsongrass. The assays were based on germination of johnsongrass pollen in media supplemented with clethodim.
