Schematic representation showing proposed detoxification pathway for 2,4,6 trinitrotoluene (TNT) in Arabidopsis roots. Mode of cellular TNT uptake and end fate of TNT-derived conjugates are still unknown. OPR, oxophytodienoate reductases; GSTs, glutathione transferases; GTases, glucosyl transferases; MRP1,2, multidrug resistance-associated protein; GGT, γ-glutamyl transpeptidase; HADNT, hydroxylamino dinitrotoluene; DNT, dinitrotoluene. Dotted lines represent putative pathways.
