Impact of the safener Mefenpyr-diethyl on herbicide resistance evolution in Alopecurus myosuroides (Huds.) biotypes

Julius-Kühn-Archiv, 2016
The evolution of herbicide resistance is an important topic in plant protection and agricultural practice. Safeners are commonly used in herbicides to protect crops against herbicidal damage.

Natural variation of response to glyphosate in Sinapis alba (Brassicaceae): Physiological effects, shikimate accumulation and genetic mechanisms

Weed Research, Volume 65, Issue 5, September/October 2025.
Abstract Glyphosate is the most widely used herbicide worldwide, and glyphosate‐resistant weeds have increased globally. Resistance mechanisms, including target‐site resistance (TSR) and non‐target‐site resistance (NTSR), are well documented, but their extent and importance are poorly understood among biotypes. This study examines the natural variation

Fitness of ALS-Inhibitors Herbicide Resistant Population of Loose Silky Bentgrass (Apera spica-venti)

Frontiers in Plant Science, 2017
Herbicide resistance is an example of plant evolution caused by an increased reliance on herbicides with few sites of action to manage weed populations.

Different nontarget‐site mechanisms underlie resistance to dicamba and 2,4‐D in an Amaranthus tuberculatus population

Pest Management Science, Volume 81, Issue 7, Page 3464-3473, July 2025.
Weak phenotypic and genetic associations between resistance to dicamba and 2,4‐D suggest that different nontarget‐site mechanisms contribute to these traits in an Amaranthus tuberculatus population from Illinois. Abstract BACKGROUND Amaranthus tuberculatus (Moq.) Sauer (waterhemp) has emerged as one of several weed species that is resistant to ...

A point mutation in IAA34 confers resistance to the auxin herbicide 2,4‐D in Sisymbrium orientale

Pest Management Science, Volume 81, Issue 7, Page 3523-3531, July 2025.
A point mutation in domain IV of SoAux/IAA34‐R provides resistance to 2,4‐D. Abstract BACKGROUND Sisymbrium orientale has evolved resistance to 2,4‐D in Australia due to a 27 bp deletion in SoIAA2. However, one population of Sisymbrium orientale resistant to 2,4‐D (R1) did not contain the SoIAA2Δ27, suggesting another 2,4‐D resistance mechanism was ...

Selection of non-target-site resistance (NTSR) to several ALS-inhibiting herbicides in three populations of Ambrosia artemisiifolia

, 2016
Ambrosia artemisiifolia is an invasive and a noxious weed. In America, it has evolved resistance to different herbicide modes of action. This study uses a recurrent selection approach to assess the capacity of A. artemisiifolia to evolve Non-Target-Site Resistance (NTSR) to ALS-inhibiting herbicides.

Multiple Origins or Widespread Gene Flow in Agricultural Fields? Regional Population Genomics of Herbicide Resistance in Bromus tectorum

Molecular Ecology, Volume 34, Issue 11, June 2025.
ABSTRACT The repeated evolution of herbicide resistance in agriculture provides an unprecedented opportunity to understand how organisms rapidly respond to strong anthropogenic‐driven selection pressure. We recently identified agricultural populations of the grass species Bromus tectorum L. with resistance to multiple herbicides.

Chromosome‐level assemblies of Amaranthus palmeri, Amaranthus retroflexus, and Amaranthus hybridus allow for genomic comparisons and identification of a sex‐determining region

The Plant Journal, Volume 121, Issue 4, February 2025.
Significance Statement We generated high‐quality genome assemblies for three economically important weeds in the Amaranthus genus. From these, we identified the sex‐determining region in a dioecious species and described important contributors to herbicide resistance in these species: cytochrome P450 gene families and extrachromosomal DNA carrying the ...

Molecular Mechanisms of Resistance to Cyhalofop-Butyl in Barnyard Grass (Echinochloa crus-galli)

Plants
Cyhalofop-butyl, a widely used acetyl-CoA carboxylase (ACCase)-inhibiting herbicide, is increasingly resisted by Echinochloa crus-galli in paddy fields. However, the physiological and molecular mechanisms of this resistance have not been fully elucidated.

Herbicide Safeners Decrease Sensitivity to Herbicides Inhibiting Acetolactate-Synthase and Likely Activate Non-Target-Site-Based Resistance Pathways in the Major Grass Weed Lolium sp. (Rye-Grass)

Frontiers in Plant Science, 2017
Herbicides are currently pivotal to control weeds and sustain food security. Herbicides must efficiently kill weeds while being as harmless as possible for crops, even crops taxonomically close to weeds.
