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.

Push It to the Limit: Identification of Novel Amino Acid Changes on the Acetolactate Synthase Enzyme of Rice That Putatively Confer High Level of Tolerance to Different Imidazolinones [PDF]
Frontiers in Bioengineering and Biotechnology, 2020 Advancements in genetically modified herbicide tolerance technology opened a new way to manage weed populations in crop fields. Since then, many important genetically modified crops that are tolerant to various herbicides have been developed and ...

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-

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

Sublethal application of various sulfonylurea and imidazolinone herbicides favors outcrossing and hybrid seed production in oilseed rape [PDF]
BMC Plant Biology, 2020 Background Acetolactate synthase (ALS)-inhibiting herbicides from the chemical families of sulfonylureas and imidazolinones are used worldwide. However, drift or sprayer contamination from some sulfonylurea herbicides causes a high level of male ...

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

Endocrine Disruptive Effects of the Herbicides Linuron, Chloridazon and Metribuzin on Bovine Granulosa Cells. [PDF]
Reprod Domest AnimABSTRACT Linuron, chloridazon and metribuzin are herbicides thought to have potential endocrine disruption (ED) effects. This study investigated the effects of linuron, chloridazon and metribuzin on bovine granulosa cell viability and oestrogen (E2) and progesterone (P4) secretion in vitro.

Degradation Enhancement as the Mechanism of Resistance to Imazethapyr in Barnyardgrass [PDF]
Planta Daninha, 2018 : Non-target site (NTS) herbicide resistance by degradation enhancement is an increasing problem in several weeds around the world. In this study, the occurrence of degradation enhancement by cytochrome P450 monooxygenases (cytP450) was evaluated as the ...
