Thirty years of glyphosate-resistant crops and weeds: Current situation and future prospects. [PDF]

Pest Manag Sci
Since 1996, when the first glyphosate‐resistant crop was commercialized and the first resistant weed was reported, resistance has expanded globally. This review analyzes emergence patterns across weed species, crops, regions, resistance mechanisms, and herbicides.

Target-site and non-target-site mechanisms confer multiple herbicide resistance in waterhemp (Amaranthus tuberculatus) accessions from Wisconsin. [PDF]

Pest Manag Sci
The A101 accession is the first confirmed case of hydroxyphenyl pyruvate dioxygenase resistance in Amaranthus tuberculatus in Wisconsin, and the first report of P450s associated with atrazine resistance in A. tuberculatus globally. Abstract BACKGROUND A preliminary screening identified a multiple herbicide‐resistant waterhemp, Amaranthus tuberculatus ...

Functional synergy and genomic linkage of glyphosate resistance traits in Canada fleabane. [PDF]

Pest Manag Sci
Stacking target‐site and non‐target‐site glyphosate resistance mechanisms in Conyza canadensis results in strong synergistic effects. This study quantifies gene × gene interactions and maps linked resistance loci, advancing our understanding of herbicide resistance genetics and informing management strategies.

Insights Into Sequences of Viral and Bacterial Origin in the Metatranscriptome of Centaurea cyanus L. Susceptible and Resistant to Acetolactate Synthase (ALS)-Inhibiting Herbicides. [PDF]

Environ Microbiol Rep
Metatranscriptomic analysis of Centaurea cyanus revealed diverse plant‐associated viral and bacterial sequences in herbicide‐susceptible and ‐resistant biotypes. While novel partitiviruses occurred independently of resistance status, differences in bacterial community composition may suggest a potential role of the plant microbiome in responses to ...

Trait Mapping Utilizing a Newly Constructed Genome for Allohexaploid Invasive Eurasian Watermilfoil (<i>Myriophyllum spicatum</i>) Reveals a Non-Target Site QTL Associated With Fluridone Resistance. [PDF]

Evol Appl
ABSTRACT Herbicides are a valuable tool in agricultural ecosystems to manage nuisance species. Due to the reliance on herbicides for weed control, herbicide resistance is a growing concern. Herbicides are also used extensively in aquatic and natural systems, but the genetics and evolutionary dynamics of resistance are not as frequently incorporated ...

Determination of the Mechanisms of MCPA Resistance in <i>Amaranthus powellii</i>. [PDF]

Plant Direct
ABSTRACT Resistance to 2‐methyl‐4‐chloro‐phenoxyacetic acid (MCPA) was recently confirmed in a population of green pigweed (Amaranthus powellii) from Dresden, Ontario, Canada, with a resistance factor of 4.4. Resistance to synthetic auxin herbicides in Amaranthus species has previously been linked to non‐target site resistance mechanisms with low‐level

Insights into ALS-inhibiting herbicide resistance in Poa annua in an arable cropping system. [PDF]

Pest Manag Sci
Variable cross‐resistance to ALS inhibitors in five Poa annua populations from wheat fields in Ireland caused by different TSR mutations. Abstract BACKGROUND Dependence on a single herbicide type to control a broad‐spectrum of weeds has resulted in cases of resistance to acetolactate synthase (ALS) inhibitors in weeds normally considered lower priority

Point Mutations as Main Resistance Mechanism Together With P450-Based Metabolism Confer Broad Resistance to Different ALS-Inhibiting Herbicides in Glebionis coronaria From Tunisia

Frontiers in Plant Science, 2021
Resistance to acetolactate synthase (ALS) inhibiting herbicides has recently been reported in Glebionis coronaria from wheat fields in northern Tunisia, where the weed is widespread. However, potential resistance mechanisms conferring resistance in these

Multiple Resistance Mechanisms Involved in Glyphosate Resistance in Eleusine indica

Plants, 2022
Glyphosate is a non-selective herbicide and is widely used for weed control in non-cultivated land in China. One susceptible (S) and five putative glyphosate-resistant (R1, R2, R3, R4, and R5) Eleusine indica biotypes were selected to investigate their ...

Target-Site and Non-target-Site Resistance Mechanisms Confer Multiple and Cross- Resistance to ALS and ACCase Inhibiting Herbicides in Lolium rigidum From Spain

Frontiers in Plant Science, 2021
Lolium rigidum is one the worst herbicide resistant (HR) weeds worldwide due to its proneness to evolve multiple and cross resistance to several sites of action (SoA).
