Development of transgenic tobacco plants overexpressing maize glutathione S-transferase I for chloroacetanilide herbicides phytoremediation
Glutathione S-transferases (GSTs, EC 2.5. 1.18) are a multigene family of detoxification
enzymes that biotransform a wide variety of endogenous and exogenous electrophilic
substrates, including herbicides. The isozyme GST I from maize exhibits significant catalytic
activity for the chloroacetanilide herbicide alachlor and appears to be involved in its
detoxifying process. To establish the in planta ability of GST I to detoxify from alachlor,
transgenesis studies were carried out. The gene gstI–6His, which encodes for 6His-tagged …
