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 ...

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 ...

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.

RNA and protein biomarkers for detecting enhanced metabolic resistance to herbicides mesosulfuron-methyl and fenoxaprop-ethyl in black-grass (Alopecurus myosuroides)

BACKGROUND: The evolution of non-target site resistance (NTSR) to herbicides leads to a significant reduction in herbicide control of agricultural weed species.

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.

The role of interspecific variability and herbicide pre-adaptation in the cinmethylin response of Alopecurus myosuroides [PDF]

BACKGROUND: Cinmethylin is an inhibitor of plant fatty acid biosynthesis, with in-plant activity caused by its binding to fatty acid thioesterases (FAT).

Evaluation and Characterization of Fitness Costs in Multiple Herbicide Resistant Echinochloa in Arkansas [PDF]

, 2018
Echinochloa spp. are major weed problems for rice (Oryza sativa L.) on a global scale. In the southern rice belt of the U.S.A., Echinochloa colona (L.) Link (junglerice) and E. crus-galli (L.) P.

Transcriptomic Analysis Identifies New Non-Target Site Glyphosate-Resistance Genes in Conyza bonariensis

Plants, 2019
Conyza bonariensis (hairy fleabane) is one of the most problematic and widespread glyphosate-resistant weeds in the world. This highly competitive weed species significantly interferes with crop growth and substantially decreases crop yield.

Weed Resistance to Herbicides in Mexico: A Review

Agronomy
Herbicide resistance in weeds has become a critical challenge in worldwide and Mexican agriculture. Many of these cases involve single, cross and multiple resistance to herbicides that inhibit Acetyl CoA Carboxylase (ACCase), Acetolactate Synthase (ALS),
