Fig. 2From: Cold regulation of plastid ascorbate peroxidases serves as a priming hub controlling ROS signaling in Arabidopsis thaliana Chlorophyll a / Chlorophyll b ratios (± standard deviation) in LTC- and STC-pre-treated plants after priming and triggering. The crude data are standardized on the values in control plants (C). The data were analyzed by ANOVA (Tukey’s test) and Student’s t-test (p < 0.05, n = 10–20). Significant differences between primed and unprimed plants are labeled with an asterisk in the left part of the figure. After triggering, significantly different data are labeled with different lettersBack to article page
