Functional categorization of E. coli genes during lambda phage induction. Histograms count number of genes significantly up-regulated (black) or down-regulated (grey) at each time interval. Genes were grouped according to the NCBI COG classification scheme[49]. Categories with an (*) were enriched in down-regulated genes (Fisher exact test, false discovery rate < 0.05): carbon catabolism, cell processes, cell structure, central metabolism energy metabolism, and transport.
