An Investigation of Tradeoffs in Herbicide Resistant Brassica rapa: Effects on Pollen and Ovule Production, Biomass and Development
TL;DR: The understanding of tradeoffs associated with herbicide resistance is expanded to include effects on components of both male and female fitness, which is significant for pollen production and overall plant development.

Multiple Resistance to Glyphosate and 2,4-D in Carduus acanthoides L. from Argentina and Alternative Control Solutions
Candelario Palma-Bautista,Pablo Belluccini,Valentin Gentiletti,José G. Vázquez-García,Hugo E. Cruz-Hipolito,Rafael De Prado +5 more
TL;DR: Findings are the first evidence of glyphosate and 2,4 D resistance in C. acanthoides, an invasive species native to Europe and distributed in other parts of the world, including North and South America.
Journal ArticleDOI
Inheritance and Molecular Characterization of a Novel Mutated AHAS Gene Responsible for the Resistance of AHAS-Inhibiting Herbicides in Rapeseed (Brassica napus L.).
TL;DR: This research identified and molecularly characterized one novel mutative AHAS allele in B. napus and laid a foundation for developing herbicide-resistant rapeseed cultivars.
Journal ArticleDOI
Cytochrome P450 BsCYP99A44 and BsCYP704A177 Confer Metabolic Resistance to ALS Herbicides in Beckmannia syzigachne
TL;DR: Results indicated that B. syzigachne and transgenic Arabidopsis displayed different cross-resistance patterns to ALS-inhibiting herbicides, and revealed that CYP99A44 and CYP704A177 protein were located in the endoplasmic reticulum.
Journal ArticleDOI
No apparent fitness costs associated with phytoene desaturase mutations conferred resistance to diflufenican and picolinafen in oriental mustard (Sisymbrium orientale L.).
TL;DR: Regression analysis showed no fitness cost in the resistant plants because no significant difference was identified in seed and biomass production within RR, RS and SS individuals, and suggests that the frequency of the PDS resistance alleles will not decline in the absence of selection pressure of PDS-inhibitors.

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
Todd A. Gaines,Wenli Zhang,Dafu Wang,Bekir Bukun,Stephen T. Chisholm,Dale L. Shaner,Scott J. Nissen,William L. Patzoldt,Patrick J. Tranel,A. Stanley Culpepper,Timothy L. Grey,Theodore M. Webster,William K. Vencill,R. Douglas Sammons,Jiming Jiang,Christopher Preston,Jan E. Leach,Philip Westra +17 more
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.
