Conjugation activities in leaf (A) and root (B) protein extracts from the Arabidopsis wild type (WT) and GST-overexpressing lines assayed using CDNB substrate. Rosette leaves were from 6-week-old plants grown in uncontaminated soil. Results are means of three biological replicates ± sd. Roots were from 2-week-old plants grown on agar plates containing 1/2 MS medium without TNT. Results are means of five biological replicates ± se. fwt, Fresh weight.
