This table shows the functional categories (funcats) annotated by MIPS [35] that respond to light and/or carbon among the 966 L/C regulated genes in wild-type (WT) and 216 L/C misregulated genes in cli186. The funcats are arranged according to their hierarchy as indicated by their numerical category. P-values to determine the significance of the funcats among the subsets of genes are shown in the columns labeled, 'L/C Regulated' and 'L/C Misregulated' in panels (a), (b) and (c). The p-values for the funcats that are significantly over-represented among both the L/C regulated genes in wild-type and the L/C misregulated genes in cli186 are in bold in panels (a), (b) and (c). The p-values for the funcats that are in normal text indicate those funcats that show over-representation among the 'L/C Regulated' or the 'L/C Misregulated' groups of genes in all panels, (a), (b) and (c). Dashes indicate no significant representation of the funcat among the groups of genes. Over-representation of MIPS terms in the gene lists were compared to the entire Arabidopsis genome (a), (c) or to the Arabidopsis multinetwork (b) using the BioMaps tool for visualization and statistical analysis, using a p value ≤ 0.05 [37, 38].
