Journal ArticleDOI
Using RNA-seq to characterize responses to 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor herbicide resistance in waterhemp (Amaranthus tuberculatus).
TL;DR: The results indicate that the response of HPPD-herbicide resistant and susceptible waterhemp genotypes toHPPD-inhibiting herbicide is rapid, established as soon as 3 hours after herbicide treatment, which could allow us to develop novel approaches for future herbicide development.
Journal ArticleDOI
Mechanisms of herbicide resistance in weeds
TL;DR: It can be concluded that crops associated to herbicide resistant weeds can be protected by applications of biochemical, genetic and crop control strategies.

Multiple modes of convergent adaptation in the spread of glyphosate-resistant Amaranthus tuberculatus
Julia M. Kreiner,Darci A. Giacomini,Felix Bemm,Bridgit Waithaka,Julian Regalado,Christa Lanz,Julia Hildebrandt,Peter H. Sikkema,Patrick J. Tranel,Detlef Weigel,John R. Stinchcombe,Stephen I. Wright +11 more
TL;DR: While the remarkable diversity of A. tuberculatus has facilitated geographic parallel adaptation of glyphosate resistance, different timescales of selection have favored either adaptation from standing variation or de novo mutation in certain parts of the range.
Journal ArticleDOI
Choosing the best cropping systems to target pleiotropic effects when managing single-gene herbicide resistance in grass weeds. A blackgrass simulation study.
TL;DR: Simulations allowed us to rank weed management practices and suggest that pleiotropic effects are extremely important for understanding the frequency of herbicide resistance in the population.
Journal ArticleDOI
Mechanisms of Lolium rigidum multiple resistance to ALS- and ACCase-inhibiting herbicides and their impact on plant fitness.
TL;DR: The recorded higher vigor and greater competitive ability of S population against wheat as compared with that of the R populations suggests an associated fitness cost with multiple resistance, and in vitro activity of the ALS enzyme confirmed that resistance to mesosulfuron-methyl + iodosulfur-methyl was due altered target-site.

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.
