13. Herbicide Safener-Binding Protein of Maize1 : Purification, Cloning, and Expression of an Encoding cDNA
Dichloroacetamide safeners protect maize (Zea mays L.) against injury from chloroacetanilide and thiocarbamate herbicides. Etiolated maize seedlings have a high-affinity cytosolic-binding site for the safener [3H](R,S)-3-dichloroacetyl-2,2,5-trimethyl-1,3-oxazol-idine ([3H]Saf), and this safener-binding activity (SafBA) is competitively inhibited by th

14. Studies on the Mode of Action of Acifluorfen-Methyl in Nonchlorophyllous Soybean Cells 1: Accumulation of Tetrapyrroles
Phytotoxic effects of the herbicide acifluorfen-methyl on nonchlorophyllous soybean cells were estimated by 86Rb leakage. An action spectrum study showed maximum injury at 350 to 450 nanometers, with lesser activity between 450 and 700 nanometers. Cells treated in the dark with acifluorfen-methyl accumulated fluorescent pigments with the spectral characteris

15. Induction of Glutathione S-Transferases in Arabidopsis by Herbicide Safeners1
Herbicide safeners increase herbicide tolerance in cereals but not in dicotyledenous crops. The reason(s) for this difference in safening is unknown. However, safener-induced protection in cereals is associated with increased expression of herbicide detoxifying enzymes, including glutathione S-transferases (GSTs). Treatment of Arabidopsis seedlings growing i
