Research on indicators for evaluating heat resistance of lettuce (Lactuca sativa L.) will improve lettuce breeding. The optimal temperature for lettuce growth is 15‑20°C. Growth inhibition emerges under high temperatures in summer. Three lettuce genotypes were used in this experiment. The leaves were used for protein extraction, SDS-PAGE and Western blot. With the increase of temperature, the expression of Hsp70 in different cultivars was increased. The expression level of Hsp70 can be a reference index for screening and identification of lettuce germplasm for tolerance to high temperature.
