Figure 7From: Increased expression of native cytosolic Cu/Zn superoxide dismutase and ascorbate peroxidase improves tolerance to oxidative and chilling stresses in cassava (Manihot esculenta Crantz)Changes of enzymatic activities of SOD (a), CAT (b), APX (c), MDHAR (d), DHAR (e) and GR (f) between WT and transgenic cassava during cold treatment. WT, wild-type control; SA1, SA2 and SA4, independent transgenic plant lines. Data presented as mean ± SD from triplicate independent measurements. *Significance at 5% level from WT by t-test, **Significance at 1% level from WT by t-test.Back to article page
