Transcription patterns of RD29B and RD29A under four rounds of dehydration stress and a diagram of the JA and dehydration stress treatments. A Transcript levels measured by real-time quantitative RT-PCR from RD29B and from RD29A genes after four cycles of exposure to dry air, annotated as dehydration stress treatments S1, S2, S3, and S4 separated by overnight periods of full recovery under water conditions annotated as R1, R2, and R3. Significantly elevated RD29B transcripts in S2, S3, and S4 compared to S1 illustrate the transcription memory response. Of note are the decreased transcript levels during water recovery (R1/R2/R3). All data represent results from three independent biological replicates; data shown indicate the mean ± SEM, n = 3. Letters above error bars indicate significant differences between stress responses (p < 0.05 according to Tukey’s multiple range test); same letters, or no assigned letters, indicate differences statistically not significant. ACT8 was used as an internal control; B schematic illustration of employed treatments. Letters above plantlets annotate specific treatments; W-mock and R1-mock annotate treatments of control (JA-untreated) plants kept for 2 h and for 22 h in water, respectively, while experimental plants were undergoing JA/recovery treatment cycles; C illustration of plants grown and handled on meshes to avoid potential tissue damage
