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 ...

Carfentrazone-ethyl resistance in an Amaranthus tuberculatus population is not mediated by amino acid alterations in the PPO2 protein.

PLoS ONE, 2019
To date, the only known mechanism conferring protoporphyrinogen IX oxidase (PPO)-inhibitor resistance in waterhemp (Amaranthus tuberculatus) is a glycine deletion in PPO2 (ΔG210), which results in cross-resistance to foliar PPO-inhibiting herbicides ...

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.

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 ...

Non-Target-Site Based Tolerance to Herbicides in Amaranthus palmeri [PDF]

, 2018
Palmer amaranth, one of the most aggressive and damaging broadleaf weeds in the USA, has evolved resistance to multiple herbicide modes of action. The overall objective of this research was to elucidate the mechanisms by which Palmer amaranth adapt to ...

Amaranthus palmeri S. Watson reproduction system: Implications for distribution and management strategies

Weed Research, Volume 65, Issue 1, January/February 2025.
Abstract Amaranthus palmeri S. Watson is one of the most troublesome weed species worldwide, and is considered one of the most devastating weeds in agricultural fields in the United States. Recently, A. palmeri populations have spread beyond their native range, into the Mediterranean region, and have been reported in several European countries ...

Target‐site resistance to ALS‐inhibiting herbicides in Stellaria media, Papaver rhoeas, Glebionis segetum and Veronica persica from Ireland

Weed Research, Volume 65, Issue 1, January/February 2025.
Abstract The increasing reliance on acetolactate synthase (ALS)‐inhibiting herbicides alone has resulted in the evolution of resistance in key broad‐leaf species in cereal farms in Ireland. Our objective was to confirm and characterise the resistance levels and mechanisms in resistance‐suspect populations (R) of Stellaria media (STEME‐R1, STEME‐R2 and ...

Population genomics of herbicide resistance in Alopecurus myosuroides [PDF]

, 2022
Over the past 50 years, herbicides have often replaced mechanical and manual human weed control, thus representing a major factor in yield productivity in modern agriculture. Herbicide applications, however, exert strong selection pressures on weeds.

Development of Brassica carinata A. Braun resistant to acetolactate synthase–inhibiting herbicides

Crop Science, Volume 64, Issue 6, Page 3339-3351, November/December 2024.
Abstract Brassica carinata A. Braun (carinata) has become an important oil crop for biofuel production in subtropical regions. Carinata is highly sensitive to acetolactate synthase (ALS)‐inhibiting herbicides, limiting its introduction into existing crop rotations.
