PCA of ICU and CC distributions. The first and second principal components (PC1 and PC2) are plotted to show the differences in the ICU and CC distributions of (top 5%) high-expression genes (H), (bottom 5%) low-expression genes (L) and all genes (A) found in the genomes of E. coli (EC), L. lactis (LL), P. pastoris (PP) and S. cerevisiae (SC). The unbiased distribution (U) is also included for each plot as reference.
