Distribution of differentially expressed genes comparing nitrogen-depleted continuous culture versus nitrogen-depleted batch culture [21]. In this comparison we included genes that were reported to be under control of GlnR [20]. a Included are all genes that were reported to be differentially expressed in continuous culture and batch culture. b Upregulated genes that are upregulated in continuous culture and batch culture and activated by GlnR. c Downregulated genes that are downregulated in continuous culture and batch culture and are repressed by GlnR. Numbers indicate the total number of genes that fall into the respective category
