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.

Different nontarget-site mechanisms underlie resistance to dicamba and 2,4-D in an Amaranthus tuberculatus population. [PDF]

Pest Manag Sci
Weak phenotypic and genetic associations between resistance to dicamba and 2,4‐D suggest that different nontarget‐site mechanisms contribute to these traits in an Amaranthus tuberculatus population from Illinois. Abstract BACKGROUND Amaranthus tuberculatus (Moq.) Sauer (waterhemp) has emerged as one of several weed species that is resistant to ...

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

Multiple Origins or Widespread Gene Flow in Agricultural Fields? Regional Population Genomics of Herbicide Resistance in Bromus tectorum. [PDF]

Mol Ecol
ABSTRACT The repeated evolution of herbicide resistance in agriculture provides an unprecedented opportunity to understand how organisms rapidly respond to strong anthropogenic‐driven selection pressure. We recently identified agricultural populations of the grass species Bromus tectorum L. with resistance to multiple herbicides.

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 ...

Resting-State Brain Activity Changes and Their Genetic Correlates in Mild Traumatic Brain Injury. [PDF]

Hum Brain Mapp
This study explores consistent patterns of resting‐state brain activity alterations in patients with mild traumatic brain injury and examines the genetic correlates associated with these neural changes. ABSTRACT Mild traumatic brain injury (mTBI) often leads to persistent cognitive and emotional symptoms, but the underlying neurobiological mechanisms ...

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 ...

Reference genes to study herbicide stress response in Lolium sp.: up-regulation of P450 genes in plants resistant to acetolactate-synthase inhibitors. [PDF]

PLoS ONE, 2013
Variation in the expression of numerous genes is at the basis of plant response to environmental stresses. Non-target-site-based resistance to herbicides (NTSR), the major threat to grass weed chemical control, is governed by a subset of the genes ...
