A novel Phe-206-Leu mutation in acetolactate synthase confers resistance to penoxsulam in barnyardgrass (Echinochloa crus-galli (L.) P. Beauv).

Pest Management Science, 2022
BACKGROUND Barnyardgrass (Echinochloa crus-galli (L.) P. Beauv) has evolved resistance to the acetolactate synthase (ALS) inhibitor penoxsulam which is used to control weeds in rice fields in China.

Overall analyses of the reactions catalyzed by acetohydroxyacid synthase/acetolactate synthase using a precolumn derivatization-HPLC method.

Analytical Biochemistry, 2022
A precolumn derivatization-HPLC method using 2,4-dinitrophenylhydrazine and 4-nitro-o-phenylenediamine as respective labeling reagents for comprehensive analyses of the reactions catalyzed by acetohydroxyacid synthase (AHAS)/acetolactate synthase (ALS ...

Crystallization of the FAD-independent acetolactate synthase of Klebsiella pneumoniae [PDF]

Acta Crystallographica Section D: Biological Crystallography, 2002
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.

A122S, A205V, D376E, W574L and S653N substitutions in acetolactate synthase (ALS) from Amaranthus palmeri show different functional impacts on herbicide resistance.

Pest Management Science, 2021
BACKGROUND Amaranthus palmeri S. Watson is a problematic weed infesting summer crops in Argentina and has developed multiple herbicide resistance. Resistance to acetolactate synthase (ALS)-inhibiting herbicides is particularly common, with high-level ...

Enhanced metabolism and target gene over-expression confer resistance against acetolactate synthase-inhibiting herbicides in Bromus sterilis.

Pest Management Science, 2020
BACKGROUND Intensive application of acetolactate synthase (ALS)-inhibiting herbicides has resulted in herbicide-resistance in many weeds, including Bromus sterilis.

Detection and characterisation of resistance to acetolactate synthase inhibiting herbicides in Anisantha and Bromus species in the United Kingdom.

Pest Management Science, 2020
BACKGROUND Anisantha and Bromus spp. are widespread and difficult to control, potentially due to the evolution of herbicide resistance. In this study, UK populations of four brome species have been tested for the early development of resistance to ...

Characterization of the acetolactate synthase gene family in sensitive and resistant biotypes of two tetraploid Monochoria weeds, M. vaginalis and M. korsakowii.

Pesticide Biochemistry and Physiology, 2020
Monochoria vaginalis and M. korsakowii are allotetraploid noxious weeds in rice cultivation. Occurrences of resistance to acetolactate synthase (ALS)-inhibiting herbicides have been reported in these weeds in Japan since the 1990s.

A Trp-574-Leu mutation in the acetolactate synthase (ALS) gene of Lithospermum arvense L. confers broad-spectrum resistance to ALS inhibitors.

Pesticide Biochemistry and Physiology, 2019
Lithospermum arvense is a troublesome dicotyledonous winter annual weed of wheat in China. A L. arvense population (HN01) suspected of being resistant to acetolactate synthase (ALS) inhibitors was found in Henan Province, China.

Isolation and expression of acetolactate synthase genes that have a rare mutation in shepherd's purse (Capsella bursa-pastoris (L.) Medik.).

Pesticide Biochemistry and Physiology, 2019
Acetolactate synthase (ALS) inhibitor-resistant biotypes are the fastest growing class of herbicide-resistant weeds. Shepherd's purse (Capsella bursa-pastoris (L.) Medik.), a tetraploid species and one of the most troublesome weeds in wheat production ...
