Freezing-stress tolerance and relative electrical conductivity of ScT3-transgenic Arabidopsis plants. a RT-PCR analysis of T3 transgenic plants. b Growth of WT (left) and transgenic (right) lines after freezing treatment. The plants were placed in a chamber at −10 °C for 2 h and then moved to normal conditions. c Survival frequency was determined after the plants recovered for 7 days under normal conditions. ** indicates significantly different values between WT and transgenic plants (P < 0.01). d Relative electrical conductivity of WT and transgenic Arabidopsis were determined after exposure to −10 °C for 2 h. ** indicates significantly different values before and after the treatment (P < 0.01). The results shown represent the means of three replicates ± SD
