Limited uptake, translocation and enhanced metabolic degradation contribute to glyphosate tolerance in Mucuna pruriens var. utilis plants
AM Rojano-Delgado, H Cruz-Hipolito, R De Prado… - Phytochemistry, 2012 - Elsevier
Velvet bean (Mucuna pruriens, Fabaceae) plants exhibits an innate, very high resistance (ie,
tolerance) to glyphosate similar to that of plants which have acquired resistance to this
herbicide as a trait. We analyzed the uptake of [14C]-glyphosate by leaves and its
translocation to meristematic tissues, and used scanning electron micrographs to further
analyze the cuticle and 3D capillary electrophoresis to investigate a putative metabolism
capable of degrading the herbicide. Velvet bean exhibited limited uptake of glyphosate and …
