Selective induction of glutathione S-transferase subunits in wheat plants exposed to the herbicide acifluorfen.
Exposure to the herbicide acifluorfen resulted in marked increase of glutathione S-transferase (GST) enzyme activity in wheat seedlings, primarily in shoot tissues. From the six major, constitutively expressed GST subunits found in untreated wheat shoots subunits 2 and 3 were selectively induced by acifluorfen. No new subunit could be detected. The induced subunits belong to those GST isoenzymes, which metabolize diphenyl ether herbicides.
