Classification of genes using PCA. The FC (A) and FCAS(B) over time are shown for wild-type yeast. Using PCA the first three scores vectors (C) are shown together with PC1-PC2 (D) and PC1-PC2-PC3 (E) plots for wild-type yeast. Corresponding PC1-PC2 plots are shown for the HXT-HXT7 (F), HXT-TM6* (G), and HXT-null (H) strains. The following colors and symbols are used: Glucose-induced genes (blue), glucose-repressed genes (red), ADH3-6 (yellow), HSP12 (black), CYC1 (green), wild-type (circles), HXT-HXT7 (squares), HXT-TM6* (triangles) and HXT-null (stars).
