Stress profiling of cuticle gene transcripts from in vitro stress treatments. Modulation of cuticle gene expression was determined in 15-d-old Arabidopsis plants subjected to different stress conditions including: water deficit (A), 150 mm NaCl (B), or 10 μm ABA (C). Water deficit treatment consisted of removal of petri dish lids and exposure of plantlets to dry air for 6 or 24 h. All other treatments lasted 24 h. The gene expression level was determined by quantitative RT-PCR analysis. Results are presented as differential relative transcript abundance. The data represent the means ± sd of three replicates. KCS6 = CER6, ECR = CER10.
