The microbiota modulates distinct functional expression nodes during postnatal development. Co-expression network analysis (CENA) was performed based on 970 co-expressed genes (correlation factor greater than 0.8 across all conditions). Each dot represents a gene and the color indicates its expression compared to the average gene expression level (red = up, blue = down). Note that ellipsoids represent only estimated visualization of transcript groups (for details see the “Methods” section). Exemplary GO terms enriched among the groups of co-regulated genes are listed, representing the main biological function of that gene group (for full list of GO terms see Additional file 10)
