The MuSI is known as a multiple stress resistant gene with several lines. A previous study using RT-PCR showed that the expression of MuSI gene in tobacco plant induced its tolerance to Cd stress. This study was conducted to examine the enhanced Cd tolerance of the MuSI transgenic tobacco plant through germination test and to understand the role of the involved antioxidant enzymes for the exhibited tolerance. Germination rate of MuSI transgenic tobacco was more than 10% higher than that of wild-type tobacco, and seedlings of MuSI transgenic tobacco grew up to 1.6 times larger and greener than seedlings of wild-type tobacco at 200 and 300 μM Cd. From the third to the fifth day, CAT activities at 100 and 200 μM Cd and APX activities at 100, 200 and 300 μM Cd of MuSI transgenic tobacco were up to two times higher than those of wild-type tobacco. MuSI gene is shown to enhance the activities of antioxidant enzymes resulting in higher tolerance to oxidative stress compared with the control plant.
