![]() The innate, higher proportional abundance, of the transport-sugar sucrose in QUI coud partly explain the higher translocation and greater sensitivity of this biotype to glyphosate. ![]() However, the total sugars decreased by âˆ❇5% in WAS, compared to âˆ❅0% decrease in QUI. Compared to QUI, in WAS, the content of aromatic amino acids was less affected by glyphosate treatment, and the content of Ala, Val, Ile, and Pro increased. Glyphosate application (80 g ae/ha) caused similar shikimate accumulation in both biotypes. Compared to the less tolerant QUI-biotype, the innate metabolism of the more tolerant WAS-biotype was characterized by a higher abundance of amino acids, and pyruvate whereas the sugar profile of the QUI biotype was dominated by the transport sugar sucrose. lacunosa (WAS and QUI) that had contrasting glyphosate tolerance. Metabolomic profiling was conducted to examine the innate physiology and the glyphosate induced perturbations in two biotypes of I. Glyphosate-tolerant Ipomoea lacunosa is emerging as a problematic weed in the southeastern United States. ![]() ![]() Maroli, Amith S Nandula, Vijay K Duke, Stephen O Gerard, Patrick Tharayil, Nishanth ![]() Comparative Metabolomic Analyses of Ipomoea lacunosa Biotypes with Contrasting Glyphosate Tolerance Captures Herbicide-Induced Differential Perturbations in Cellular Physiology. ![]()
