BIIDXI expression during thermotolerance and thermomemory. (A) Schematic representation of the protocol (based on Olas et al. [29]). Seedlings were collected and frozen immediately at the beginning and at the end of priming (T₀P and EndP), 24 h after the end of priming (24HP), 72 h after priming/start of triggering (T₀T), at the end of triggering (EndT), and 4 days after triggering (4dpT). (B) BIIDXI expression within the priming, including sublethal heat treatment (C) on the BIIDXI expression level during triggering. The expression values are relative to T₀P expression. Error bars indicate S.D. (n = 4). Statistical analyses were performed using Student’s t-test. Asterisks indicate statistically significant differences to T₀P (* p < 0.05, ** p < 0.01, *** p < 0.001, ns, not significant).
