Priming of leaves in different developmental stages of a 6-week-old rosette. Six week old plants were primed and triggered according to the experimental design (Fig. 7) and harvested after the triggering stimulus was applied. (A) The transcript abundance was measured for the primable ROS marker genes ZAT10 and BAP1 and normalized to the geometric mean of two constitutively expressed genes. Additionally the non-primable cold marker gene COR15A was analysed. (B) Transcript levels of the early senescence gene ORE1 were determined in the same samples as quantitative measure for the onset of senescence. An ANOVA (Tukey’s test, p < 0.05, n = 3 ± SD) was performed. The small letters refer to significance groups with leaf sets of the same age and different capital letters show significant differences between different age groups.
