Color-coded expression-profile table of the genes selected from the cell-cycle data by permutation test. Abscissa, cell-cycle phase groups; ordinate, genes. The cycle phase groups and the genes are arranged according to the angular position in the PCA biplot (see Figure 3). Upregulation, red; downregulation, green. The figure was generated using Michael Eisen's software TreeView .
