Identification and expression of main genes involved in non-target site resistance mechanisms to fenoxaprop-p-ethyl in Beckmannia syzigachne.

Pest Management Science, 2020
BACKGRAOUD Non-target-site resistance (NTSR) to herbicide is a serious threat to global agriculture. Though the metabolic resistance was the dominant mechanism of NTSR, the molecular mechanism is not yet well-characterized.

Pinoxaden resistance in Lolium perenne L. is due to both target-site and non-target-site mechanisms

Pesticide Biochemistry and Physiology, 2022
Application of herbicides inhibiting acetyl CoA carboxylase (ACCase) has been one of the main strategies for selectively controlling grass weed species such as perennial ryegrass (Lolium perenne L.) in wheat and barley crops in New Zealand. In this study, we have confirmed and characterized resistance to pinoxaden, an ACCase-inhibiting herbicide, in a ...

Evidence for the association of target-site resistance in cyp51 with reduced DMI sensitivity in European Cercospora beticola field isolates.

Pest Management Science, 2020
BACKGROUND Cercospora leaf spot caused by Cercospora beticola is the most relevant foliar disease in sugar beet cultivation. In the last decade a decreasing sensitivity of C. beticola towards demethylation inhibitors (DMIs) occurred. Different mechanisms

Non-target-site herbicide resistance: a family business

Trends in Plant Science, 2007
We have witnessed a dramatic increase in the frequency and diversity of herbicide-resistant weed biotypes over the past two decades, which poses a threat to the sustainability of agriculture at both local and global levels. In addition, non-target-site mechanisms of herbicide resistance seem to be increasingly implicated.

Target-site and non-target-site based resistance to clodinafop-propargyl in wild oats (Avena fatua L.)

Pesticide Biochemistry and Physiology, 2023
Wild oat (Avena fatua L.) is a common and problematic weed in wheat fields in China. In recent years, farmers found it increasingly difficult to control A. fatua using acetyl-CoA carboxylase (ACCase)-inhibiting herbicides. The purpose of this study was to identify the molecular basis of clodinafop-propargyl resistance in A. fatua.

Overcoming drug resistance: targeting more than one site

Leukemia Research, 2002
Activation of the molecular machinery of programmed cell death (apoptosis) is a convergence point for many cytotoxic agents, irrespective of the primary mechanism of action. Indeed, apoptosis is induced in response to DNA strand breaks caused by such mechanistically diverse anti-leukemic drugs as the nucleoside cytosine arabinoside (ara-C ...

Target-site and non-target-site-based resistance to tribenuron-methyl in multiply-resistant Myosoton aquaticum L.

Pesticide Biochemistry and Physiology, 2019
Myosoton aquaticum L., a widespread and competitive winter weed of wheat in China, has evolved resistance to many classes of herbicides. In one M. aquaticum population (AH03), collected from Anhui Province, where tribenuron-methyl and florasulam had been used to control this weed resistance to both herbicides had evolved.

Cross-resistance to photosystem II inhibitors observed in target site–resistant but not in non–target site resistant common ragweed (Ambrosia artemisiifolia)

Weed Science, 2022
AbstractThe full spectrum of herbicide resistance in a weed can vary according to the mechanistic basis and cannot be implied from the selective pressure. Common ragweed (Ambrosia artemisiifolia L.) is an important weed species of horticultural crops that has developed resistance to linuron based on either target site– or non–target site resistance ...

R-factor trimethoprim resistance mechanism: An insusceptible target site

Biochemical and Biophysical Research Communications, 1974
Abstract R-factor R388 increases the resistance of Escherichia coli to trimethoprim by 10,000 fold, and mediates the synthesis of an addional dihydrofolate reductase that is less susceptible to trimethoprim by a similar order of magnitude. The dihydrofolate reductase conferred by the R-factor was of a larger molecular weight than the wild-type ...

Target-site and non-target-site resistance mechanisms confer mesosulfuron-methyl resistance in Alopecurus aequalis

Plant Physiology and Biochemistry
Shortawn foxtail (Alopecurus aequalis Sobol.) is a noxious weed in China. The resistance of A. aequalis developed rapidly due to the long-term application of acetolactate synthase (ALS)-inhibiting herbicides. Here, a suspected mesosulfuron-methyl-resistant A.
