Glutathione S-transferases in Festuca arundinacea: Identification, characterization and inducibility by safener benoxacor

Shoots of Festuca arundinacea were submitted to a chromatographic procedure, by combination of anionic, affinity and RP-HPLC chromatography, to identify the glutathione S-transferase enzymes (GSTs). Four GST isoforms were identified: FaGST I, FaGST II, FaGST III and FaGST IV. Among these significant differences were observed in the chromatographic behaviours, structure, activity and responsiveness to the herbicide safener benoxacor.
