Figure 2.

Comparison of significant overrepresented functional gene categories (and sub-categories) of lumichrome-treated lotus and tomato roots determined by PAGEMAN. The values are representative of the log2 transformed values of three individual hybridizations, statistically analyzed via robust multichip averaging (RMA) in R, and classed according to the MAPMAN classifications (Thimm et al., 2004; Usadel et al., 2005) and over-representation classification assessed via Wilcoxon rank sum test (P < 0.05; Usadel et al., 2006). Red indicates a decrease whereas blue indicates an increase (see color scale).
