Resistance detection of blackjack to ALS inhibitors by in vitro plant growth method [PDF]

Planta Daninha, 2020
Background: The resistance of weeds to herbicides is a problem that has been increasingly studied because of its great importance in agriculture and rapid growth of this phenomenon worldwide. The quick detection of resistant plants is extremely important

Resistance patterns of a bur chervil (Anthriscus caucalis M. Bieb.) population with a point mutation within the acetolactate synthase gene in comparison with sensitive bur chervil and further weedy Apiaceae species

Julius-Kühn-Archiv, 2022
Weeds of the umbelliferous family (Apiaceae) are gaining importance in several crops and regions and are often difficult to control chemically. For example, the occurrence of bur chervil (Anthriscus caucalis M.

Sulfonylurea resistance in Amaranthus hybridus from southern Brazil [PDF]

Revista Ceres, 2022
Amaranthus hybridus is a C4 broadleaf species widely spread across Brazilian agricultural territory. Recently, several herbicide resistance reports have been documented in southern Brazil, including the reports for enolpyruvilshikymate-3-phosphate (EPSPS)

Regulation of Tobacco Acetolactate Synthase Gene Expression [PDF]

Plant Physiology, 1993
Acetolactate synthase (ALS) catalyzes the first common step in the biosynthesis of isoleucine, leucine, and valine. The previous cloning of two tobacco (Nicotiana tabacum) ALS genes (SurA and SurB) has allowed transcript accumulation from these genes to be monitored. mRNA blot analysis of ALS transcripts showed a message size of 2.2 kb. Quantitation of

Structure and mechanism of acetolactate decarboxylase [PDF]

, 2013
Acetolactate decarboxylase catalyzes the conversion of both enantiomers of acetolactate to the (R)-enantiomer of acetoin, via a mechanism that has been shown to involve a prior rearrangement of the non-natural (R)-enantiomer substrate to the natural (S ...

Control of barnyardgrass susceptible and resistant to imidazolinones at different temperature regimes before and after imazethapyr application

Pesquisa Agropecuária Tropical, 2022
Environmental conditions can influence herbicide metabolism and interfere with the evolution of weed resistance. This study aimed to evaluate the effect of thermal regimes on the control of barnyardgrass (Echinochloa crus-galli) susceptible ...

Resistance of Amaranthus retroflexus to acetolactate synthase inhibitor herbicides in Brazil [PDF]

Planta Daninha, 2014
When in competition with cotton, Amaranthus retroflexus can cause high yield losses. Due to the limited availability of selective herbicides registered for post emergence control of this weed, the same herbicides have been used repeated times over the ...

Degradative acetolactate synthase of Bacillus subtilis: purification and properties [PDF]

Journal of Bacteriology, 1975
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,

Resistence of Radish Biotypes to Iodosulfuron and Alternative Control [PDF]

Planta Daninha, 2016
The repetitive use of iodosulfuron for the control of weeds in winter cereals in the south of Brazil has favored the emergence of resistant Raphanus sativus biotypes.
