Genetic diversity and population structure of ALS-resistant Amaranthus hybridus across Brazil's primary soybean-growing regions. [PDF]

Pest Manag Sci
We identified two distinct target‐site mutations, Asp‐376‐Glu and Trp‐574‐Leu, that confer resistance to acetolactate synthase inhibitors in Amaranthus hybridus populations across Brazil's soybean‐growing regions. These findings suggest multiple independent origins of resistance, with its spread primarily driven by local herbicide selection pressure ...

Divergence in Glyphosate Susceptibility between Steinchisma laxum Populations Involves a Pro106Ser Mutation

Plants, 2023
The characterization of the mechanisms conferring resistance to herbicides in weeds is essential for developing effective management programs. This study was focused on characterizing the resistance level and the main mechanisms that confer resistance to

PfGSTF2 endows resistance to quizalofop-p-ethyl in Polypogon fugax by GSH conjugation. [PDF]

Plant Biotechnol J
Summary Populations of Polypogon fugax have developed resistance to many acetyl‐CoA carboxylase (ACCase)‐inhibiting herbicides. This resistance threats the effectiveness and sustainability of herbicide use. In our previous research, a field P. fugax population exhibited GST‐based metabolic resistance to the widely used ACCase‐inhibiting herbicide ...

Reference genes to study herbicide stress response in Lolium sp.: up-regulation of P450 genes in plants resistant to acetolactate-synthase inhibitors. [PDF]

PLoS ONE, 2013
Variation in the expression of numerous genes is at the basis of plant response to environmental stresses. Non-target-site-based resistance to herbicides (NTSR), the major threat to grass weed chemical control, is governed by a subset of the genes ...

Genetic Mechanism of Non-Targeted-Site Resistance to Diquat in Spirodela polyrhiza

Plants
Understanding non-target-site resistance (NTSR) to herbicides represents a pressing challenge as NTSR is widespread in many weeds. Using giant duckweed (Spirodela polyrhiza) as a model, we systematically investigated genetic and molecular mechanisms of ...

Mechanism of Resistance to S-metolachlor in Palmer amaranth

Frontiers in Plant Science, 2021
Herbicides are major tools for effective weed management. The evolution of resistance to herbicides in weedy species, especially contributed by non-target-site-based resistance (NTSR) is a worrisome issue in crop production globally. Glyphosate-resistant

Degradation and metabolism of fenoxaprop-P-ethyl in sensitive and resistant populations of Alopecurus myosuroides

Julius-Kühn-Archiv, 2014
Blackgrass (Alopecurus myosuroides) is one of the most economically important weeds in Europe. Because of the development and distribution of herbicide resistant populations the control of this weed has become a serious challenge in agriculture.

Integrated genomic and transcriptomic approaches reveal oxidative stress adaptation mechanisms in a mesotrione‐resistant Amaranthus tuberculatus biotype

Pest Management Science, Volume 82, Issue 7, Page 6387-6398, July 2026.
Integrated GWAS and transcriptomics in a Canadian waterhemp biotype reveal mesotrione resistance is polygenic and metabolically driven. Significant SNPs and 187 herbicide‐responsive genes point to enhanced redox homeostasis, glutathione‐linked detoxification, lipid/secondary metabolism, and oxidative stress responses. Resistance arises from coordinated,

Can Control of Glyphosate Susceptible and Resistant Conyza sumatrensis Populations Be Dependent on the Herbicide Formulation or Adjuvants?

Agronomy, 2020
In this work, we studied the effect of three glyphosate formulations (isopropylamine, ammonium and potassium salts) and two non-ionic adjuvants on the resistance response of two resistant (R1, R2) and one susceptible population of the highly invasive ...

Diverse mechanisms associated with cyhalofop-butyl resistance in Chinese sprangletop (Leptochloa chinensis (L.) Nees): Characterization of target-site mutations and metabolic resistance-related genes in two resistant populations

Frontiers in Plant Science, 2022
Resistance of Chinese sprangletop (Leptochloa chinensis (L.) Nees) to the herbicide cyhalofop-butyl has recently become a severe problem in rice cultivation. However, the molecular mechanisms of target-site resistance (TSR) in cyhalofop-butyl-resistant L.
