Relative ZAT10 (top) and BAP1 (bottom) transcript levels in ΔsAPX and ΔtAPX lines (knock-out lines) of Arabidopsis thaliana after LTC- (dark blue bars) or STC-priming (white bars) and triggering with a 24 h cold stimulus. The values in PT-plants were divided by the values of T-plants. The data were analyzed by ANOVA (Tukey’s test; p < 0.05, n = 3). Significant increases and decreases relative to “PT = T” (dotted line) are labeled with an asterisk. Significantly lower inhibition of transcript induction relative to the response in Col-0 (Fig. 4) (Student’s t-test; p < 0.05, n = 3–6) are labeled with a black triangle
