Metabolic profiling of glyphosate-resistant sourgrass (Digitaria insularis)

open access: yesWeed Technology, 2020
AbstractPutative glyphosate-resistant sourgrass was collected to determine its resistance level and to evaluate its metabolic profile after resistance. Although accumulation of shikimic acid is known to occur in glyphosate-susceptible populations, differences in the ability of resistant (R) and susceptible (S) biotypes to accumulate quinic acid ...
