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

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 ...

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 ...

Spontaneous and pharmacologically induced hypothermia protect mice against endotoxic shock

British Journal of Pharmacology, Volume 182, Issue 12, Page 2621-2641, June 2025.
Background and Purpose Despite the well‐known occurrence of hypothermia during sepsis, its underlying biological nature and adaptive value remain debated. Experimental Approach Using indirect calorimetry, telemetry, thermal gradient studies and pharmacological studies, we examined the thermal and metabolic responses of mice treated with a shock ...

Chromosome-level genome assembly of triploid Cyperus rotundus uncovers allelic expression patterns and herbicide resistance mechanisms

Plant Communications
Cyperus rotundus, a globally distributed and highly competitive weed, has evolved herbicide resistance, posing a significant challenge to sustainable agriculture; however, the lack of genomic resources has limited comprehensive investigations into its ...

Maintenance of metabolic homeostasis and induction of cytoprotectants and secondary metabolites in alachlor-treated GmGSTU4-overexpressing tobacco plants, as resolved by metabolomics [PDF]

, 2015
Herbicides are an invaluable tool for agricultural production scaling up. However, their continuous and intensive use has led to an increased incidence of herbicide resistant weeds and environmental pollution.

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 ...

The impacts of conservation agriculture on crop yield in China depend on specific practices, crops and cropping regions

Crop Journal, 2014
For smooth and wide application of conservation agriculture (CA), remaining uncertainties about its impacts on crop yield need to be reduced. Based on previous field experiments in China, a meta-analysis was performed to quantify the actual impacts of CA
