Figure 10From: OsTCTP, encoding a translationally controlled tumor protein, plays an important role in mercury tolerance in riceAnalysis of GSH content, H2O2 level and antioxidant enzyme activities in roots of the wild type (WT), vector control (VC), OsTCTP-OX and OsTCTP-RNAi transgenic rice plants. (A) The total GSH content in roots of WT (cv. ‘Nipponbare’), VC (vector control), OsTCTP-RNAi (#10 and #17) and OsTCTP-OX (#12 and #14). (B) The H2O2 levels in roots of WT (cv. ‘Nipponbare’), VC (vector control), OsTCTP-RNAi (#10 and #17) and OsTCTP-OX (#12 and #14). (C) Superoxide dismutase (SOD) activity. (D) Catalase (CAT) activity. (E) Ascorbate peroxidase (APX) activity. (F) Peroxidase (POD) activity. Data are given as means ± SD of three biological replicates. Means with different letters are significantly different (P < 0.05, Tukey’s test).Back to article page
