• Mechanisms of Resistance to Glyphosate in a Ryegrass (Lolium Multiflorum) Biotype from Chile (2007, background): “(Argentina) (Heap 2007; Powles and Preston 2006).”
• Glyphosate and Multiple Herbicide Resistance in Common Waterhemp (Amaranthus rudis) Populations from Missouri (2008, background): “Other authors have also suggested that several mechanisms responsible for glyphosate resistance could co-occur in a resistant weed species (Powles and Preston 2006; Westwood and Weller 1997; Zelaya and Owen 2005).”
• Evolution in action: plants resistant to herbicides. (2010, background): “Mechanisms endowing evolved glyphosate resistance in weeds have recently been reviewed, showing that both target-site EPSPS gene mutation/amplification and non-target-site resistance (discussed below) have evolved (133, 143, 158).”
• Glyphosate-Resistant Italian Ryegrass (Lolium multiflorum) in California: Distribution, Response to Glyphosate, and Molecular Evidence for an Altered Target Enzyme (2008, background): “…proline residue at site 106 of the target enzyme EPSPS, have been identified in glyphosate-resistant individuals of other weed populations and species, including Italian ryegrass, rigid ryegrass, and goosegrass (reviewed in Powles and Preston 2006; also see Perez-Jones et al. 2007; Yu et al. 2007).”
• Gene amplification confers glyphosate resistance in Amaranthus palmeri (2009, background): “Target site mutations in the EPSPS gene confer 2- to 3-fold glyphosate resistance in several other weedy species (15).”
• Widespread occurrence of multiple herbicide resistance in Western Australian annual ryegrass (Lolium rigidum) populations (2007, background): “Although glyphosateresistant ryegrass has been documented in WA (Neve et al. 2004) and elsewhere in Australia (Preston 2005, reviewed in Powles and Preston 2006; Broster and Pratley 2006), in this random survey of crop fields, glyphosate remained effective on almost all of the ryegrass populations.”
• Detection of Sourgrass (Digitaria insularis) Biotypes Resistant to Glyphosate in Brazil (2011, background): “This fact indicates that the glyphosate uptake might be slower in this weed species, because the accumulation of shikimic acid is an indicator of whether or not glyphosate is reaching the target enzyme (Powles and Preston 2006).”
• Herbicide Resistance: Toward an Understanding of Resistance Development and the Impact of Herbicide-Resistant Crops (2012, background): “This is the primary (but not only) weed-resistance mechanism reported for ALS-inhibitors, ACCase-inhibitors, mitotic inhibitors, PPO-inhibitors, and some PSII-inhibiting herbicides (Powles and Preston 1995, 2006).”
• Glyphosate-resistant Hairy Fleabane (Conyza Bonariensis) in Spain (2007, background): “…from mutations that confer an enzyme 5-enolpyruvyl-shikimate-3-phosphate synthase (EPSPS) that is weakly resistant to glyphosate, and the nontarget-site mechanism results in a reduction in translocation of the herbicide to meristematic tissues (Dinelli et al., 2006; Powles and Preston 2006).”
• Proactive Versus Reactive Management of Glyphosate-Resistant or -Tolerant Weeds1 (2005, background): “Glyphosate resistance developed slowly in the United States for several reasons (Powles and Preston 2006), but a major consideration was the limited initial selection pressure on the various weed popula- tions.”
• Evolution of Glyphosate-Resistant Johnsongrass (Sorghum halepense) in Glyphosate-Resistant Soybean (2007, background): “In recent years, populations of several weed species have been confirmed as glyphosate resistant in different cropping systems worldwide (reviewed in Owen and Zelaya 2005; Powles and Preston 2006; Powles and Wilcut 2007; Vila-Aiub et al. 2007).”
