Reduced absorption and impaired translocation endows glyphosate resistance in Amaranthus palmeri harvested in GR soybean from Argentina

Amaranthus palmeri S. Watson is probably the worst glyphosate-resistant (GR) weed worldwide. The EPSPS (5-enolpyruvylshikimate-3-phosphate-synthase) gene amplification has been reported as the major target-site-resistance (TSR) mechanism conferring resistance to glyphosate in this species. In this s...

The EPSPS (5-enolpyruvylshikimate-3-phosphate-synthase) gene amplification has been reported as the major target-site-resistance (TSR) mechanism conferring resistance to glyphosate in this species. In this study, TSR and non-target-site-resistance (NTSR) mechanisms to glyphosate were characterized in a putative resistant A. palmeri population (GRP), harvested in a GR-soybean crop from Argentina. Glyphosate resistance was confirmed for the GRP population by dose-response assays. No evidence of TSR mechanisms as well as glyphosate metabolism was found in this population. Moreover, a susceptible population (GSP) that absorbed about 10% more herbicide than the GRP population was evaluated at different periods after treatment. The GSP population translocated about 20% more glyphosate to the remainder of the shoots and roots at 96 h after treatment than the control, while the GRP population retained 62% of herbicide in the treated leaves. This is the first case of glyphosate resistance in A. palmeri involving exclusively NTSR mechanisms.This research was funded by the MINECO-Spain (Grant AGL2016-78944-R).(c) American Chemical Society, 20192019info:eu-repo/semantics/articleinfo:eu-repo/semantics/acceptedVersionapplication/pdfhttps://doi.org/10.1021/acs.jafc.8b06105http://hdl.handle.net/10459.1/65598reponame:Repositori Obert UdL instname:Universitat de Lleida (UdL)Inglésinfo:eu-repo/grantAgreement/MINECO//AGL2016-78944-RVersió postprint del document publicat a: https://doi.org/10.1021/acs.jafc.8b06105Journal of Agricultural and Food Chemistry, 2019, vol. 67, núm. 4, p. 1052–1060(c) American Chemical Society, 2019info:eu-repo/semantics/openAccessoai:repositori.udl.cat:10459.1/655982026-06-24T12:42:17Z
