Figure 5. Co-expression conservation.† A. Conservation of components in the multiple species network.† Each box in the heat-map represents the percent of links connected to a meta-gene in one organism that are also present in the multiple species co-expression network.† Gray indicates where a meta-gene lacked an ortholog in a particular organism.† The columns correspond to flies, humans, worms, and yeast respectively.† The final column shows the expression conservation index for the meta-gene. (18)The average conservation degree for all meta-genes in the component is shown beneath the componentís heat-map.† Scale shows the conservation degree.† B. Shown is component 11 that is composed almost entirely of animal-specific meta-genes (yellow boxes) and component 9 that is composed primarily of meta-genes containing a yeast ortholog (blue boxes).
