CORRECTIONS Vol. 166: 1255–1268, 2014 Ge X., d’Avignon D.A., Ackerman J.J.H., and Sammons R.D. In Vivo 31P-Nuclear Magnetic Resonance Studies of Glyphosate Uptake, Vacuolar Sequestration, and Tonoplast Pump Activity in Glyphosate-Resistant Horseweed. Figure 7 showed incorrect chemical structures of glyphosate (PMG) and N-methyl glyphosate (NMG). Both structures should have included an additional –CH2- group between the nitrogen and the carbonyl group. The revised Figure 7 included below shows the corrected chemical structures.
