[i] Gene numbers for each category and each list of coexpressed genes are shown. Clusters of sexual differentiation genes are from Mata et al. (2002), and the corresponding percentage data are shown in Figures 2 and 3. Stress genes induced during the core environmental stress response (CESR) are from Chen et al. (2003). Gene numbers depend on the cutoffs used and represent estimates.
