Functional enrichment analysis based on different gene expression patterns. (A) Expression profiles in color indicate significant ones (p < 0.05). Green, up-regulated; red, down-regulated. Profile number (up left), gene number (bottom left), and trend (line) in each profile were labelled. The significant terms were graphed using (B) GO annotation (p < 0.001, FDR < 0.05), and (C) KEGG pathway annotation (p < 0.05). Tawny block, pattern 4; teal block, pattern 3; red block, pattern 0.
