Enhanced Metabolism Evolved High-Level Resistance to Fenoxaprop-P-Ethyl in Alopecurus japonicus

Agronomy, 2022
Alopecurus japonicus has been a serious weed across China and developed resistance to the acetyl-CoA carboxylase (ACCase)-inhibiting herbicide. The A. japonicus ACCase gene mutations accounting for target-site resistance (TSR) have been clarified, while ...

The analysis of reference genes expression stability in susceptible and resistant Apera spica-venti populations under herbicide treatment

Scientific Reports, 2021
Weed resistance to herbicides constitutes a serious problem to world crop production. One of the weeds that are significantly threatening the crops’ yield and quality is Apera spica-venti. The target-site resistance (TSR) mechanism of A.

Current Status of Herbicide Resistance in the Iberian Peninsula: Future Trends and Challenges

Agronomy, 2022
The evolution of herbicide resistance in weeds has emerged as one of the most serious threats to sustainable food production systems, which necessitates the evaluation of herbicides to determine their efficacy.

Distribution of Glyphosate-Resistance in Echinochloa crus-galli Across Agriculture Areas in the Iberian Peninsula

Frontiers in Plant Science, 2021
The levels of resistance to glyphosate of 13 barnyard grass (Echinochloa crus-galli) populations harvested across different agriculture areas in the Southern Iberian Peninsula were determined in greenhouse and laboratory experiments.

miR397/Laccase Gene Mediated Network Improves Tolerance to Fenoxaprop-P-ethyl in Beckmannia syzigachne and Oryza sativa

Frontiers in Plant Science, 2017
Herbicide resistance can be either target-site or non-target-site based. The molecular mechanisms underlying non-target-site resistance (NTSR) are poorly understood, especially at the level of gene expression regulation.

Cytochrome P450 Herbicide Metabolism as the Main Mechanism of Cross-Resistance to ACCase- and ALS-Inhibitors in Lolium spp. Populations From Argentina: A Molecular Approach in Characterization and Detection

Frontiers in Plant Science, 2020
Knowledge about the mechanisms of herbicide resistance provide valuable insights into evolving weed populations in response to selection pressure and should be used as a basis for designing management strategies for herbicide-resistant weeds.

Coexistence of target-site and non-target-site mechanisms of glyphosate resistance in Amaranthus palmeri populations from Argentina

Acta Scientiarum. Agronomy, 2021
Amaranthus palmeri S. Waston is currently one of the most problematic weeds worldwide. Biotypes with resistance to herbicides such as glyphosate and ALS inhibitors are now present in almost all Argentinian cultivable areas.

Accumulation of Target Gene Mutations Confers Multiple Resistance to ALS, ACCase, and EPSPS Inhibitors in Lolium Species in Chile

Frontiers in Plant Science, 2020
Different Lolium species, common weeds in cereal fields and fruit orchards in Chile, were reported showing isolated resistance to the acetyl CoA carboxylase (ACCase), acetolactate synthase (ALS) and 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS ...

Asp376Glu Mutation and Enhanced Metabolism Controlling the Resistance to ALS-Inhibiting Herbicides in Ixophorus unisetus (J. Presl) Schltdl. from the Bajio, Mexico

Agronomy, 2023
A study was carried out to determine the ALS (acetolactate synthase)-inhibitor herbicide resistance in the Mexican grass Ixophorus unisetus, a troublesome weed in corn crops in Mexico. First, the resistance was confirmed in field screening assays.
