Abstract

Abstract: HS-6-SFT transgenic tobacco and non-transgenic tobacco W38 were used as materials under low temperature stress at 4 ℃ for 8 h. The differences of soluble protein, superoxide dismutase（SOD）, catalase CAT, peroxidase（POD） between transgenic tobacco and non-transgenic tobacco were analyzed. The results showed that the soluble protein content, SOD activity, CAT activity and POD activity in tobacco leaves increased, and the increase at 4 ℃ was larger than that at room temperature. There was a very significant difference between the transgenic materials and the control（P<0.01）. The stress resistance of transgenic tobacco with HS-6-SFT gene is enhanced.

Key words: transgenic tobacco, superoxide dismutase, catalase, peroxidase, soluble protein, low temperature stress
