The adh1-2 mutant is less tolerant to freezing damage. The semi lethal temperature (LT50) was determined according to the electrical conductivity in Wild-type and adh1-1 and adh1-2 mutant plants. The error bars indicate standard errors (n = 6). (A,C) All plants were grown at 23°C for 5 weeks, and direct determined of the conductivity and the semi lethal temperature. (B,D) All plants were grown at 23°C for 4 weeks, and 4°C for 7 d, following determination of the conductivity and the semi lethal temperature.
