From: Comprehensive transcriptional profiling of NaCl-stressed Arabidopsis roots reveals novel classes of responsive genes

Figure 2

NaCl-responsive transcripts grouped according to temporal expression profiles. Microarray expression data that had been previously filtered for significance based on signal intensity and SAM [21] statistical analysis, was divided into 16 distinct temporal profiles, using STEM software [22]. Each of the profiles (labelled a-o) is represented as a different plot, with mean expression ratios (log2; treated:control) for each of the assigned transcripts at each time point plotted in grey. The median of all assigned expression ratios in each profile is plotted in black. To emphasize that the y-axis range is different between plots, a dashed line corresponding to a log2expression ratio of 0 is also shown in each plot.
