Figure 4From: Differential patterns of reactive oxygen species and antioxidative mechanisms during atrazine injury and sucrose-induced tolerance in Arabidopsis thaliana plantletsEffects of atrazine and sucrose on SOD enzyme activity. SOD activity was 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). SOD activity is expressed in unit/g FW as defined in Methods. Statistical analysis was carried out as described in Methods.Back to article page
