Atrazine resistance and plants made resistant by genetic engineering

4 Atrazine resistance and plants made resistant by genetic engineering 

Another common resistance mechanism is enhanced detoxication in plants. Atrazine has an electrophilic carbon that may be attacked by glutathione, and biotypes of various weeds may have glutathione transferases that have a better ability to catalyze this reaction  

The data in Table 9.4 are extracted from data of Plaisance and Gronwald (1999) and show the difference in the activity of glutathione transferase. In this case there was no difference in the total amount of enzyme protein or activity toward the standard substrate. The inheritance of this resistance mechanism is in a nuclear gene.
