Generation of imidazolinone herbicide resistant trait in Arabidopsis

PLOS ONE, 2020
Recently-emerged base editing technologies could create single base mutations at precise genomic positions without generation DNA double strand breaks. Herbicide resistant mutations have been successfully introduced to different plant species, including ...

Stacked mutations in multi-copy AHAS genes enhance sulfonylurea herbicide resistance in soybean. [PDF]

Plant J
SUMMARY Weeds are a major factor that negatively impact crop yields. Developing herbicide‐resistant germlines is crucial for efficient weed control. Sulfonylurea‐ and pyrimidinyl benzoate‐based herbicides inhibit the function of acetohydroxyacid synthase (AHAS), a key enzyme in the biosynthesis of branched‐chain amino acids in plants. To create soybean

A Brief History of Canola Genetic Gains: From Classical Breeding to Genome Editing. [PDF]

Physiol Plant
ABSTRACT Canola exemplifies the transformation of a crop from industrial use to a globally significant edible oilseed through sustained genetic and biotechnological innovation. Historically, rapeseed was characterized by high erucic acid and glucosinolate contents, restricting its use primarily to industrial applications.

Development and Breeding of Herbicide-Resistant Sorghum for Effective Cereal-Legume Intercropping. [PDF]

Adv Sci (Weinh)
This study identified two SbALS mutations (A93T and S624N) conferring robust herbicide resistance in sorghum, facilitating efficient weed control. Structural analysis revealed that imazamox resistance is mediated by disrupted herbicide binding. Furthermore, 126 imazamox resistant soybean varieties are screened for sorghum‐soybean intercropping ...

Tolerance to Imidazolinone Herbicides in Wheat [PDF]

Plant Physiology, 1992
An imidazolinone-tolerant wheat (Triticum aestivum L. em Thell) mutant in the winter wheat cultivar Fidel has been identified and characterized. The mutant was isolated from a population derived through seed mutagenesis of the variety with an aqueous solution containing sodium azide.

Genetic diversity and population structure of ALS-resistant Amaranthus hybridus across Brazil's primary soybean-growing regions. [PDF]

Pest Manag Sci
We identified two distinct target‐site mutations, Asp‐376‐Glu and Trp‐574‐Leu, that confer resistance to acetolactate synthase inhibitors in Amaranthus hybridus populations across Brazil's soybean‐growing regions. These findings suggest multiple independent origins of resistance, with its spread primarily driven by local herbicide selection pressure ...

Imidazolinones [PDF]

Plant Physiology, 1984
The imidazolinones, a new chemical class of herbicides, were shown to be uncompetitive inhibitors of acetohydroxyacid synthase from corn. This is the first common enzyme in the biosynthetic pathway for valine, leucine, and isoleucine. The K(i) for the imidazolinones tested ranged from 2 to 12 micromolar.

Field and laboratory assessments of sugarcane mutants selected in vitro for resistance to imazapyr herbicide [PDF]

Crop Breeding and Applied Biotechnology, 2017
Seven imazapyr-tolerant mutant sugarcane plants, previously generated by in vitro mutagenesis, were studied. The imazapyr concentrations required to inhibit their acetolactate synthase (ALS basal activity) (IC50 as μmoles acetoin h-1 mg-1 protein) were 0.

Leaching of Imidazolinones in Irrigation Systems in Rice Cultivation: Sprinkling and Flooding [PDF]

Planta Daninha, 2019
: Herbicides of the imidazolinone group have been used in irrigated rice and presented a long persistence in the soil, especially in floodplain areas with a low drainage, and could cause environmental contamination.
