Figure 5From: Metabolic regulation of Escherichia coli and its phoB and phoR genes knockout mutants under phosphate and nitrogen limitations as well as at acidic conditionComparison of the transcript levels of the wild type cultivated at 100% and 20% N-limitation and phoB mutant cultivated at 20% N-limitation: (a) global regulatory genes, (b) PhoB regulatory genes, (c) nitrogen regulatory genes, (d) metabolic pathway genes, and (e) respiratory chain genes.Back to article page
