Glyphosate resistance in Ambrosia trifida: Part 2. Rapid response physiology and non-target-site resistance.

Pest Management Science, 2018
AbstractBACKGROUNDThe glyphosate‐resistant rapid response (GR RR) resistance mechanism in Ambrosia trifida is not due to target‐site resistance (TSR) mechanisms. This study explores the physiology of the rapid response and the possibility of reduced translocation and vacuolar sequestration as non‐target‐site resistance (NTSR) mechanisms.RESULTSGR RR ...

A quantitative genetic examination of non‐target‐site resistance applied to Avena species

Weed Research, 2018
SummaryQuantitative genetics tools can be used to assess whether using herbicides at low doses drive selection on standing genetic variation in populations leading to non‐target‐site resistance (NTSR). These tools are particularly important for estimating the number of genes involved and the potential speed of evolution.

Non-target Site Mechanisms of Resistance to Herbicides

Critical Reviews in Plant Sciences, 2017
ABSTRACTEvolution of resistance in weeds to herbicides is threatening world agricultural production. Weed management has become more complicated with the development of non-target site resistance (NTSR) to herbicides in weeds. The NTSR mechanisms can be caused by herbicide metabolism, altered patterns of translocation, and herbicide absorption ...

Non-target-site resistance to ALS-inhibiting herbicides in a Sagittaria trifolia L. population.

Pesticide Biochemistry and Physiology, 2017
Sagittaria trifolia L. is one of the most competitive weeds in rice fields in northeastern China. The continuous use of acetolactate synthase (ALS)-inhibitors has led to the evolution of herbicide resistant S. trifolia. A subpopulation BC1, which was derived from the L1 population, was analyzed using DNA sequencing and ALS enzyme activity assays and ...

Non-target-site resistance mechanism of barnyardgrass [Echinochloa crus-galli (L.) P. Beauv.] to florpyrauxifen-benzyl.

Pest Management Science, 2021
BACKGROUND Florpyrauxifen-benzyl (FPB) is an arylpicolinate herbicide (Group IV) for barnyardgrass control in rice. One susceptible (Sus) and three putative FPB-resistant (R1, R2, and R3) barnyardgrass biotypes were selected based on resistant ...

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.

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.

Confirmation and Characterization of Non–Target Site Resistance to Fomesafen in Palmer Amaranth (Amaranthus palmeri)

Weed science, 2018
Palmer amaranth (Amaranthus palmeri S. Watson), a dioecious summer annual species, is one of the most troublesome weeds in U.S. cropping systems. The evolution of resistance to protoporphyrinogen oxidase inhibitors in A. palmeri biotypes is a major cause

Transcript Profiling of Non‐Target‐Site Imidazolinone Resistance in Imisun Sunflower

Crop Science, 2018
Imidazolinone resistance found in a wild sunflower (Helianthus annuus L.) population was successfully transferred to a cultivated inbred line developing ‘Imisun’ sunflowers. Genetic regulation of this trait has been reported to involve two genes: Imr1, an allelic variant of ahasl1 locus that codes for acetohydroxyacid synthase catalytic subunit, and ...
