Journal ArticleDOI
Genetic basis, evolutionary origin and spread of resistance to herbicides inhibiting acetolactate synthase in common groundsel (Senecio vulgaris)
TL;DR: In this article, the authors investigated the evolutionary origin and spread of resistance in the tetraploid species Senecio vulgaris (common groundsel), a widespread, highly mobile weed.
Journal ArticleDOI
Identification and expression of main genes involved in non‐target site resistance mechanisms to fenoxaprop‐p‐ethyl in Beckmannia syzigachne
TL;DR: This work demonstrates that the NTSR mechanism by means of enhanced detoxification of fenoxaprop-p-ethyl in American sloughgrass is very likely driven by the herbicide metabolism related genes.
Journal ArticleDOI
Sequencing the Plastid Genome of Giant Ragweed (Ambrosia trifida, Asteraceae) From a Herbarium Specimen.
TL;DR: The first plastome sequence of giant ragweed (Ambrosia trifida) is reported and the phylogeny of Asteraceae and the transcriptional profiling against glyphosate resistance in Giant ragweed is assessed, providing hints toward the ecological adaptation of the genus.
Journal ArticleDOI
Fitness costs associated with acetyl-coenzyme A carboxylase mutations endowing herbicide resistance in American sloughgrass (Beckmannia syzigachne Steud.).
TL;DR: The Ile1781Leu, Ile2041Asn, and Gly2096Ala mutations displayed no obvious fitness costs or displayed very small fitness penalties, which would likely have no effect on the establishment of resistant weeds in the field.
Journal ArticleDOI
A Trp-574-Leu mutation in the acetolactate synthase (ALS) gene of Lithospermum arvense L. confers broad-spectrum resistance to ALS inhibitors
TL;DR: In in vitro ALS assays, the concentration of tribenuron-methyl required to inhibit 50% ALS activity for HN01 was 117-fold greater than that required to inhibits a susceptible population (HN05), indicating that resistance was due to reduced sensitivity of the ALS enzyme to tribenur-methyl.

Crop losses to pests
TL;DR: Despite a clear increase in pesticide use, crop losses have not significantly decreased during the last 40 years, however, pesticide use has enabled farmers to modify production systems and to increase crop productivity without sustaining the higher losses likely to occur from an increased susceptibility to the damaging effect of pests.
Journal ArticleDOI
Environmental and Economic Costs of Nonindigenous Species in the United States
TL;DR: Aproximately 50,000 nonindigenous (non-native) species are estimated to have been introduced to the United States, many of which are beneficial but have caused major economic losses in agriculture, forestry, and several other segments of the US economy, in addition to harming the environment.

Evolution in Action: Plants Resistant to Herbicides
Stephen B. Powles,Qin Yu +1 more
TL;DR: Understanding resistance and building sustainable solutions to herbicide resistance evolution are necessary and worthy challenges to herbicides sustainability in world agriculture.
Journal ArticleDOI
The genetics of human adaptation: hard sweeps, soft sweeps, and polygenic adaptation.
TL;DR: This work argues for alternatives to the hard sweep model: in particular, polygenic adaptation could allow rapid adaptation while not producing classical signatures of selective sweeps, and discusses some of the likely opportunities for progress in the field.

Gene amplification confers glyphosate resistance in Amaranthus palmeri

TL;DR: This work investigated recently discovered glyphosate-resistant Amaranthus palmeri populations from Georgia, in comparison with normally sensitive populations, and revealed that EPSPS genes were present on every chromosome and, therefore, gene amplification was likely not caused by unequal chromosome crossing over.
