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 ...

Cross resistance to accase herbicide in Lolium rigidum.

Communications in agricultural and applied biological sciences, 2005
Lolium rigidum is a cross-pollinating grass weed present in Europe and occurring in winter wheat and orchard crops. Several graminicides such as chlorotoluron and/or isoproturon and diclofop-methyl in mixtures or alone have been used successfully to control this weed in Spain during the past decade. However, several L rigidum populations have developed

Cross‐resistance patterns to ACCase‐inhibiting herbicides conferred by mutant ACCase isoforms in Alopecurus myosuroides Huds. (black‐grass), re‐examined at the recommended herbicide field rate

Pest Management Science, 2008
AbstractBACKGROUND: Target‐site‐based resistance to acetyl‐CoA carboxylase (ACCase) inhibitors in Alopecurus myosuroides Huds. is essentially due to five substitutions (Isoleucine‐1781‐Leucine, Tryptophan‐2027‐Cysteine, Isoleucine‐2041‐Asparagine, Aspartate‐2078‐Glycine, Glycine‐2096‐Alanine).

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.

Target-Site Based Resistance to Accase Inhibitors

1997
The enzyme acetyl-coenzyme A carboxylase (ACCase; E.C. 6.4.1.2) is the target site of two major groups of synthetic herbicides, the aryloxyphenoxypropanoates (AOPP) and cyclohexanodiones (CHD). ACCase is a key enzyme in the biosynthesis of acyl lipids, catalyzing the addition of HCO 3 - to acetate to form malonate, a precursor of fatty acid ...

Resistance patterns and molecular basis to ACCase-inhibiting herbicides

Weed Science
AbstractDigitaria ciliaris var. chrysoblephara (Fig. & De Not.) R.R. Stewart is an annual xeromorphic weed that severely infests direct-seeded rice fields in China. Herbicide resistance is emerging in D. ciliaris var. chrysoblephara owing to extensive and recurrent use of the acetyl-CoA carboxylase (ACCase)-inhibiting herbicide metamifop.

Characterization and expression of Arabidopsis biotin carboxylase subunit of the plastidic ACCase and partial purification of soybean plastidic ACCase

I report the molecular cloning and sequence of the cDNA and gene coding for the BC subunit of the fhloroplastic ACCase of Arabidopsis thaliana (CAC2). The BC protein is coded by a single gene, containing 15 introns and 16 exons. The promoter of BC has some special domains, such as two 529 bp cis-repeats at positions -1410 to -882 and -559 to -47, the ...

Resistance to ACCase-inhibiting herbicides in the weed Lolium multiflorum.

Communications in agricultural and applied biological sciences, 2009
Resistance to five ACCase-inhibiting herbicides (dictofop, fluazifop, tralkoxydim, cycloxydim and pinoxaden) was investigated in 55 Lolium multiflorum populations from 50 farms in England. Resistance screening experiments at whole plant level showed differences in the response to each herbicide suggesting different resistance mechanisms for different ...
