Overview of evolutionary co-expressed conserved modules across three organisms.

The most enriched GO term from the biological process subtree amongst the genes in each module is shown (left column). The numbers of co-expressed modules showing enrichment in the same term are grouped (right column). Conserved co-expressed modules across E. coli, B. subtilis, and S. enterica are their corresponding module numbers as in Table S2. The module numbers related to large evolutionary conserved co-expressed module, which contain at least 16 genes in their core part, are highlighted by bold characters.
