Pathogen induced expression of selected P450s. Microarray expression data were retrieved from the 'Genevestigator' database and processed as described in Methods. Selected genes that are up-regulated (>twofold) in more than 30% of at least one treatment group as indicated on top are shown. The complete set of genes fulfilling this criterion is shown in Additional File 2. Background corrected expression intensities were compared to untreated control experiments and log2-ratios were used for visualization. The resulting heatmap is color coded as indicated. Details on the individual samples can be found in Additional File 2.
