Dispersal and genetic variability of Sonchus oleraceus L. in relation to its resistance to ALS-inhibiting herbicides. [PDF]

open access: yes, 2011
The work described in this thesis investigates the existence and level of acetolactate synthase (ALS)-inhibiting herbicide resistance in Sonchus oleraceus in Australia. It further discusses the sensitivity of different S.

Identifying resistance‐conferring cytochrome P450s in weeds: experimental strategies and practical considerations

open access: yesPest Management Science, EarlyView.
Identifying resistance‐conferring cytochrome P450s requires integrating weed characterization, gene discovery and functional validation. No single approach is sufficient to distinguish causal resistance genes from herbicide‐metabolizing enzymes. Abstract Cytochrome P450 monooxygenases (P450s) play a pivotal role in metabolic herbicide resistance, yet ...

Structural and Kinetic Comparison of Acetolactate Synthase and Acetohydroxyacid Synthase from Klebsielle pneumoniae

open access: yes, 2019
Acetolactate synthase (ALS) and acetohydroxyacid synthase (AHAS) are two thiamin diphosphate (ThDP)-dependent enzymes that catalyze the formation of acetolactate from two molecules of pyruvate. In addition to acetolactate, AHAS can catalyze the formation

The continuing significance of chiral agrochemicals

open access: yesPest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Resistance of Echinochloa crus-galli Populations to Acetolactate Synthase-Inhibiting Herbicides

open access: yesInternational Journal of Agronomy, 2012
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.

Retrospective Identification of Lactococcus petauri Among Archived Isolates From Farmed Fish in Japan: Pathogenicity and Molecular Epidemiology

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Lactococcosis, caused by Lactococcus garvieae, L. formosensis, and L. petauri, is an important bacterial disease of farmed fish worldwide. In Japan, L. petauri has not previously been reported as a cause of lactococcosis, although lactococcosis cases not attributable to either L. garvieae or L. formosensis have been recorded.

Acetolactate Synthase Overexpression in Mesosulfuron-Methyl-Resistant Shortawn Foxtail ( Alopecurus aequalis Sobol.): Reference Gene Selection and Herbicide Target Gene Expression Analysis.

open access: yesJournal of Agricultural and Food Chemistry, 2018
Severe infestations of shortawn foxtail ( Alopecurus aequalis Sobol.), a noxious weed in wheat and canola cropping systems in China, remain standing even after the application of the herbicides, fenoxaprop- P-ethyl and mesosulfuron-methyl.
