Enrichment for GO and MapMan terms in co-expression networks.

<p>Enrichment of highly co-expressed interactions among sets of genes in the network was calculated using both the Gene Ontology (GO) standard as well as the MapMan (MM) standard using the Z-test. Interactions among random sets of genes with the same size as GO and MM were calculated and compared to empirical interactions showing that interaction densities in empirical data are stronger in both networks for both GO (<b>A</b>) and MM (<b>B</b>). Individual annotation terms are plotted against each other in each network (<b>C–D</b>) showing that certain terms are more represented in a single network (green and blue points) or represented by both networks (red points).
