Figure 4

PageMan display of MapMan gene categories affected by Alethea and salinity. The Wilcoxon rank sum test was used to identify functional groups where the distribution of responses within a group differed from the response of the entire gene set under test. The figure is based on gene expression ratio data for relevant pair-wise treatment comparisons. Treatment groups are identified using two-letter abbreviations, where the first letter indicates the pre-treatment (W; water, A; Alethea) and the second letter the main treatment (W; water, S; salt). Coloured boxes indicate statistically-significant groups (Benjamini & Hochberg-corrected P-value below 0.05). The colour scale represents z-transformed P-values, with red shades indicating a trend within the group for up-regulation of expression relative to the control, and blue shades, down-regulation. Text alongside each row provides MapMan annotation of differentially regulated gene classes.
