Herbicide resistance in the Canadian prairie provinces : Five years after the fact [PDF]

, 1994
La résistance aux herbicides a été reconnue comme un problème pour la première fois dans les Prairies canadiennes, en 1988, quand une sétaire verte (Setaria viridis) résistante à la trifluraline a été détectée au Manitoba, puis une stellaire moyenne ...

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Coupling of both a transactivation module and a double‐stranded DNA‐binding domain boosts Cas12i3 variant‐based cytosine and adenine editing in plants

Journal of Integrative Plant Biology, EarlyView.
Fusions of a transactivation module and a double‐stranded DNA‐binding domain produced effective Cas12i3 variant‐based cytosine and adenine base editors, with improved C‐to‐T and A‐to‐G base editing efficiency and expanded editing window. Generated herbicide‐resistant rice germplasm by using these base editors demonstrates their potential for precise ...

A nonsynonymous mutation in an acetolactate synthase gene (Gh_D10G1253) is required for tolerance to imidazolinone herbicides in cotton

Journal of Cotton Research, 2023
Background Herbicide tolerance in crops enables them to survive when lethal doses of herbicides are applied to surrounding weeds. Herbicide-tolerant crops can be developed through transgenic approaches or traditional mutagenesis approaches.

Novel Mutation in the Acetohydroxyacid Synthase (AHAS), Gene Confers Imidazolinone Resistance in Chickpea Cicer arietinum L. Plants

Plants, 2021
Chickpea (Cicer arietinum L.) is an important crop in crop-rotation management in Israel. Imidazolinone herbicides have a wide spectrum of weed control, but chickpea plants are sensitive to acetohydroxyacid synthase (AHAS; also known as acetolactate ...

The Capital–Labour–State Dynamics of Herbicide Adoption in Rainfed India

Journal of Agrarian Change, EarlyView.
ABSTRACT This paper engages debates around the capital–labour–state dynamics of agrarian transitions to address the oft‐studied but still little‐understood question of why farmers adopt herbicides when they do. Over the last several years, smallholder farmers in India have begun using the herbicide bispyribac sodium at breakneck speeds, particularly in

Natural and artificial evolution of acetolactate synthase for crop breeding

Crop Journal
Acetolactate synthase (ALS)-targeting herbicides are among the most widely used weed-control chemicals globally. Mutations in the ALS gene can confer herbicide resistance in crops, thereby allowing selective elimination of weeds without harming crops ...

Characterization of the acetohydroxyacid synthase multigene family in the tetraploide plant Chenopodium quinoa

Electronic Journal of Biotechnology, 2015
Background: Currently, the technology called Clearfield® is used in the development of crops resistant to herbicides that inhibit the enzyme acetohydroxy acid synthase (AHAS, EC 2.2.1.6). AHAS is the first enzyme of the biosynthetic pathway that produces

Molecular Targeted Suppression of Male Fertility in Amaranthus palmeri S. Watson: Function and Layered Double Hydroxide Nanosheets‐Based Delivery System of ApmiR319

Plant Biotechnology Journal, EarlyView.
ABSTRACT Amaranthus palmeri is one of the most troublesome invasive agricultural weeds worldwide, exhibiting super invasiveness and high resistance to conventional management strategies. Artificial microRNA‐mediated silencing technology, coupled with a nanoparticle‐mediated delivery system, represents an attractive approach for fertility control in A ...
