Fig. 6From: Cold regulation of plastid ascorbate peroxidases serves as a priming hub controlling ROS signaling in Arabidopsis thaliana The transcript levels of genes for chloroplast antioxidant enzymes immediately, 24 h and 120 h after priming and immediately and 24 h after 24 h triggering at 4 °C in LTC-primed plants. The transcript levels were normalized to the transcript levels of naïve plants before the on-set of priming. Significant differences between primed and unprimed plants (Student’s t-test; p < 0.05, n = 3–6) are labelled with an asterisk in the left part of the figure. After triggering, significantly different data (Tukey’s test; p < 0.05, n = 3–6) are labelled with different letters. The samples were labelled as in Fig. 1 Back to article page
