FIG. 2.—
Comparison of expression level (a), codon adaptation index (b), and relative amino acid substitution rates (c) among the modules. A matrix representation of post hoc multiple comparison results (α = 0.05, using Tukey test). Cell aij in the matrix is colored red if the corresponding variable module i > module j, blue if module i < module j, and white if no significant difference between the modules was found.
