• Herbicide Resistance: Toward an Understanding of Resistance Development and the Impact of Herbicide-Resistant Crops (2012, background): “A special case of target-site resistance has been associated with glyphosate-resistance in some weed species where an amplification of the target site is noted (Gaines et al. 2010).”
• Impact of Genetic Background in Fitness Cost Studies: An Example from Glyphosate-Resistant Palmer Amaranth (2014, methodology): “In Palmer amaranth with EPSPS gene amplification, mutated copies of the gene have not been found (Gaines et al. 2010).”
• Structural variant calling: the long and the short of it (2019, background): “…be associated with aluminum resistance [24]; (ii) an amplification of Bot1 plays an important role in boron toxicity in barley [25]; and (iii) for weeds, a tolerance against the herbicide glyphosate based on amplification of EPSPS has been reported in response to extensive use of glyphosate [26].”
• Genetically Engineered Herbicide-Resistant Crops and Herbicide-Resistant Weed Evolution in the United States (2017, neutral): “Some have gone so far as to claim that, if left unchecked, herbicide resistance could “ threaten the sustainability ” of some crop production systems (Gaines et al. 2010).”
• Modelling evolution and management of glyphosate resistance in Amaranthus palmeri (2011, background): “There have been no published studies of the inheritance of 293 glyphosate resistance in A. palmeri, though a study by Gaines et al. (2010) has reported an 294 increase in copy number of the 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) target 295 enzyme for glyphosate in populations from…”
• Multiple Resistance to Herbicides from Four Site-of-Action Groups in Waterhemp (Amaranthus tuberculatus) (2013, methodology): “Quantitative PCR (qPCR) was used to measure EPSPS copy number relative to ALS essentially as described previously (Gaines et al. 2010).”
• Glyphosate Resistance in Tall Waterhemp (Amaranthus tuberculatus) from Mississippi is due to both Altered Target-Site and Nontarget-Site Mechanisms (2013, methodology): “(Westra et al. 2013), and Palmer amaranth (Gaines et al. 2010; Ribeiro et al. 2011).”
• Impacts of genetically engineered crops on pesticide use in the U.S. -- the first sixteen years (2012, background): “Resistant weed populations from Georgia contained 5-fold to 160-fold more copies of the EPSPS gene, compared to susceptible plants [26].”
• Review: Confirmation of Resistance to Herbicides and Evaluation of Resistance Levels (2013, background): “In Palmer amaranth, resistance to glyphosate is due to severalfold amplification of the EPSPS gene (Gaines et al. 2010).”
