Differential induction of glutathione transferases and glucosyltransferases in wheat, maize and Arabidopsis thaliana by herbicide safeners.
By learning lessons from weed science we have adopted three approaches to make plants more effective in phytoremediation: (1) The application of functional genomics to identify key components involved in the detoxification of, or tolerance to, xenobiotics for use in subsequent genetic engineering/breeding programmes. (2) The rational metabolic engineering of plants through the use of forced evo...
متن کاملProtective Responses Induced by 3-Dichloroacetyl Oxazolidine Safeners in Maize (Zea mays)
The protective effect of herbicide safener R-28725 and chiral 3-dichloroacetyl oxazolidine safeners in reducing the phytotoxicity of chlorsulfuron to maize were studied by physiological and biochemical tests. The results showed that R-28725 and compound A [(R)-3-dichloroacetyl-2,2-dimethyl-4-ethyl-1,3-oxazolidine] could improve the GSH content, GST activity (in vivo and in vitro), ALS activity ...
متن کاملMilestones in the Development of Herbicide Safeners*
The concept o f using chemical safeners to improve herbicide selectivity became widely known in 1969 with the introduction o f naphthalic anhydride (N A ) to improve the tolerance o f maize to thiocarbamate herbicides. Soon thereafter dichlormid was also developed as a safener for thiocarbamates in maize. At present there are at least eight different chemical safeners that have been developed c...
متن کاملInduction of glutathione S-transferases in Arabidopsis by herbicide safeners.
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 in liquid medium with various safeners...
متن کاملHerbicide Safeners: Effective Tools to Improve Herbicide Selectivity
Herbicide safeners, formerly referred to as herbicide antidotes, are chemical agents that increase the tolerance of monocotyledonous cereal plants to herbicides without affecting the weed control effectiveness. The use of safeners offer several benefits to agricultural weed control. Safeners may allow: (1) the selective chemical control of weeds in botanically related crops; (2) the use of nons...
