FIGURE 1.
Thermotolerance of the lsm5/sad1 mutant after heat stress treatment. (A) Photographs of wild-type and lsm5/sad1 mutants after heat stress treatment. The survival rate (B) and chlorophyll content (C) of heat-treated wild-type and lsm5/sad1 mutant after heat stress at various temperatures. Five-day-old seedlings of the wild-type and lsm5/sad1 mutant were subjected to various temperatures for 90 min, and then returned to 22°C under the light, and photographs, survival rate and chlorophyll content were obtained after 9-days of growth. (B,C) The values are means ± SEM of the result from five plates (∼25 plants per plate) of individual lines.
