• Gene amplification confers glyphosate resistance in Amaranthus palmeri (2009, background): “rigidum, and EPSPS from glyphosate-resistant and -susceptible plants were equally sensitive to glyphosate (31).”
• Importance of the P106S Target-Site Mutation in Conferring Resistance to Glyphosate in a Goosegrass (Eleusine indica) Population from the Philippines (2008, background): “It is well documented that mutations in prolyl106 of EPSPS decrease the Ki for glyphosate (Baerson et al. 2002b; Comai et al. 1983, 1985; Ng et al. 2004a; Stalker et al. 1985; Yuan et al. 2005).”
• Glyphosate Tolerance Mechanism in Italian Ryegrass (Lolium multiflorum) from Mississippi (2008, background): “On the other hand, an amino acid change at position 106 from Pro to Ser in the epsps gene conferring glyphosate resistance was reported in goosegrass (Baerson et al. 2002b).”
• A Decade of Glyphosate-Resistant Lolium around the World: Mechanisms, Genes, Fitness, and Agronomic Management (2009, background): “At least two populations have been found without a target site mutation or decreased translocation of glyphosate (Baerson et al. 2002b; Preston and Wakelin 2008).”
• Role of absorption and translocation in the mechanism of glyphosate resistance in horseweed (Conyza canadensis) (2005, background): “Subsequent studies showed no evidence for gene amplification or cosegregation of a specific 5-enolpyruvylshikimate3-phosphate synthase (EPSPS) gene variant with glyphosate resistance, suggesting that the resistance mechanism may be nontarget based (Baerson et al. 2002).”
• Evolution in action: plants resistant to herbicides. (2010, background): “rigidum (8), and a complementary role of constitutively higher EPSPS mRNA levels was suggested for several glyphosate-resistant Conyza biotypes, where reduced glyphosate translocation was found to be a major resistance mechanism (37).”
• A rapid in vivo shikimate accumulation assay with excised leaf discs (2005, methodology): “The in vitro assay was used to determine that a GR goosegrass population has a less sensitive target site (Baerson et al. 2002) and that a GR ryegrass population did not (Baerson et al. 2000).”
