Figure 5

Effects of atrazine and sucrose on antioxidative enzyme activities. Activities of ascorbate peroxidase (APX) (A), dehydroascorbate reductase (DHAR) (B), monodehydroascorbate reductase (MDAR) (C), glutathione reductase (GR) (D) and catalase (CAT) (E) were measured in protein extracts from 3-week-old MS-grown Arabidopsis thaliana plantlets subjected to subsequent treatment (48 hours) with 80 mM mannitol (M), 80 mM sucrose (S), 80 mM mannitol plus 10 μM atrazine (MA) or 80 mM sucrose plus 10 μM atrazine (SA). Enzymatic activities are expressed in nkatal/g FW, nkatal corresponds to the amount of enzymatic activity that catalyzes the transformation of one nmole of substrate per second. Statistical analysis was carried out as described in Methods.
