Figure 6: Overlap of differentially expressed genes among conditions.
From: The E. coli molecular phenotype under different growth conditions

For all differentially expressed genes (identified as in Fig. 5), we determined to what extent they were unique to specific conditions or appeared in multiple conditions. For simplicity, we here lumped all carbon-source experiments, all sodium experiments, and all magnesium experiments into one group each. Overall, we found relatively little overlap in the differentially expressed genes among these conditions. (A) mRNA, exponential phase. (B) protein, exponential phase. (C) mRNA, stationary phase. (D) protein, stationary phase.
