ttl-1 and b1l ttl mutants were both more tolerant to freezing than WT under non-acclimation conditions. Freezing tolerance (a, c) and survival rates (b, d) of 3-week-old WT, b1l, ttl-1, and b1l ttl under non-acclimated (NA) or cold-acclimated (CA) conditions. Seven-day-old seedlings grown on MS plates were transplanted to soil and grown at 22 °C for 2 weeks under long day conditions (light:dark, 16 h:8 h). The plants were then treated at − 10 °C for 1 h (NA) or were pretreated at 4 °C for 3 days and then treated at − 10 °C for 6 h (CA). For each line, the survival rate assay was performed with approximately 64 plants and then scored 5 days later. The data are shown as the means of four independent biological replicates ± SEM. Asterisks indicate significant differences (*p < 0.05) from the wild type
