Selectivity of Iodosulfuron-Methyl to Oat Cultivars [PDF]
Weeds are among the main constraints to high grain yield on hexaploid oat (Avena sativa), but there are few herbicides registered for weed control on this cereal crop. The objectives of this study were to evaluate the impact of the iodosulfuron-methyl on

Degradative acetolactate synthase of Bacillus subtilis: purification and properties [PDF]
A degradative acetolactate synthase (acetolactate pyruvate-lyase [carboxylating], EC 4.1.3.18) from Bacillus subtilis has been partially purified and characterized. The synthesis of the enzyme was induced by growth of cells in minimal medium plus isobutyrate or acetate. The enzyme was partially purified by ammonium sulfate fractionation, gel filtration,

Acetolactate Synthase Inhibiting Herbicides Bind to the Regulatory Site [PDF]
Acetolactate synthase from spontaneous mutants of tobacco (Nicotiana tabacum; KS-43 and SK-53) and cotton (Gossypium hirsutum; PS-3, PSH-91, and DO-2) selected in tissue culture for resistance to a triazolopyrimidine sulfonanilide showed varying degrees of insensitivity to feedback inhibitor(s) valine and/or leucine.

Characterization of Two Forms of Acetolactate Synthase from Barley [PDF]
Acetolactate synthase (ALS) catalyzes the first common step in the biosynthesis of valine, leucine, and isoleucine. ALS is the target site for several classes of herbicides, including sulfonylureas, imidazolinones, and triazolopyrimidines. Two forms of ALS (designated ALS I and ALS II) were separated from barley shoots by heparin affinity column ...

Properties of Mutant Acetolactate Synthases Resistant to Triazolopyrimidine Sulfonanilide [PDF]
Triazolopyrimidine sulfanilides are a class of highly active herbicides whose primary target is acetolactate synthase. Spontaneous mutants of tobacco (Nicotiana tabacum) (KS-43) and cotton (Gossypium hirsutum) (PS-3 and DO-2) resistant to triazolopyrimidine sulfonanilide were selected in tissue culture. Acetolactate synthase partially purified from the

Resistance of Echinochloa crus-galli Populations to Acetolactate Synthase-Inhibiting Herbicides
Three Echinochloa crus-galli (barnyardgrass) populations from rice fields in Arkansas (AR1 and AR2) and Mississippi (MS1), USA, were recently confirmed to be resistant to imazethapyr.

Efficient biochemical production of acetoin from carbon dioxide using Cupriavidus necator H16
Background Cupriavidus necator is the best-studied knallgas (also termed hydrogen oxidizing) bacterium and provides a model organism for studying the production of the storage polymer polyhydroxybutyrate (PHB).

Identification of the optimal codons for acetolactate synthase from weeds: an in-silico study
Although various studies of codon usage bias have been reported in a broad spectrum of organisms, no studies to date have examined codon usage bias for herbicide target genes. In this study, we analysed codon usage patterns for the acetolactate synthase (

Crystallization of the FAD-independent acetolactate synthase ofKlebsiella pneumoniae [PDF]
Leucine and valine are formed in a common pathway from pyruvate in which the first intermediate is 2-acetolactate. In some bacteria, this compound also has a catabolic fate as the starting point for the butanediol fermentation. The enzyme (EC 4.1.3.18) that forms 2-acetolactate is known as either acetohydroxyacid synthase (AHAS) or acetolactate ...

Natural and artificial evolution of acetolactate synthase for crop breeding
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 ...
