Figure 2.

Gene expression profiles from plants treated with hypoxia and low atmospheric pressure compared with Earth-normal controls. A, The induction and repression of gene activity is represented by the variance normalized score (Vnorm) for each sample against the average of the two control samples. Only those genes demonstrating significant treatment effects are shown. The Venn diagrams show the overlap between the hypoxia and low-pressure treatments. B, The A and C clusters from the indicated regions in A are shown, with the ANOVA value for the data and the average -fold increase or decrease in gene activity, together with the gene identifiers and brief annotations. Genes directly involved in dehydration responses are indicated by blue background in the annotations. Cluster B (genes coordinately down regulated in both treatments) annotations can be found in the supplemental data.
