| Abstract: | Glutathione (GSH) can be found in plants in considerable amounts. It is very important for numerous metabolic functions and for the detoxification of xenobiotics. The present study was carried out to show the inducibility of glutathione S-transferase (GST) isozymes in spruce by various substrates commonly used to assay GST activity, Inducers were: chloro-2,4-dinitrobenzene (CDNB), 1,2-dichloro-4-nitrobenzene (DCNB), para-nitrobenzoylchloride (pNBC), fluorodifen and n-ethylmaleinimide (NEM). Conjugation of CDNB was enhanced by the xenobiotics ranking in the order: CDNB > fluorodifen > pNBC > NEM > DCNB. |
