Figure 3

Estimated gene network including core clock genes. The gene network was estimated by the SiGN-BN program from the 1,000 targets with the highest coefficient of variation, and 886 targets connected to the edge with bootstrap probability higher than 0.7 are illustrated here. Red nodes indicate core clock genes, and the other colors indicate the peak time of expression of the target. Since some genes were analyzed by several microarray probes, there were several red nodes for clock genes.
