Subgenomic Distribution and Herbicide Cross-Resistance of <i>ALS</i> Gene Mutations in Allohexaploid <i>Echinochloa crus-galli</i>. [PDF]

Plant Direct
ABSTRACT Herbicide target site resistance in polyploid species is more complex than in diploids due to potential subgenome interactions. This study characterized mutations in the ALS gene across distinct subgenomes of hexaploid Echinochloa crus‐galli and evaluated the cross‐resistance patterns conferred by each mutation to various ALS‐inhibiting ...

Agrestal Environments and Maternal Genetic Effects Weaken the Ecological Barriers for Crop to Wild Introgression in Sunflower. [PDF]

Ecol Evol
We highlight how agrestal environments and maternal effects may facilitate the adaptation of crop‐wild hybrid sunflower to agroecosystems. We present two consecutive years of data on diverse wild and reciprocal crop‐wild hybrid sunflower populations planted in three contrasting, ruderal or agrestal, environments. We found that (i) agrestal environments

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.

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.

Absolute quantification of fluorescent protein fusions by mass spectrometry. [PDF]

Protein Sci
Abstract Fusions with fluorescent proteins (FPs) play a pivotal role in experimental biology because of their sensitive and spatially precise visualization by spectroscopy. However, observed fluorescence is not always proportional to their molar concentration.

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.

Catalytic Diastereo- and Enantioselective Synthesis of 2-Imidazolinones [PDF]

Organic Letters, 2019
Chiral cyclic ureas (2-imidazolinones) were prepared by the reaction of nitrones and isocyanoacetate esters using a multicatalytic system that combines a bifunctional Brønsted base-squaramide organocatalyst and Ag+ as a Lewis acid. The reaction could be achieved with a range of nitrones derived from aryl- and cycloalkylaldehydes with moderate diastereo-

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 ...

Carryover of Imazethapyr + Imazapic on Ryegrass and Non-tolerant Rice as Affected by Thickness of Soil Profile [PDF]

Planta Daninha, 2015
Herbicides used in Clearfield(r) rice system may persist in the environment, damaging non-tolerant crops sown in succession and/or rotation. These damages vary according to soil characteristics, climate and soil management.
