Model of sRNA involvement in the chemical stress response in E. coli. An overview of differentially expressed annotated sRNAs during chemical stress with acids and organic solvents. Only sRNAs with significant expression changes in the presence of three or four out of the four acids or four organic solvents are included (filled orange squares, acids; filled green squares, organic solvents). Small RNAs with differential expression in multiple chemical stress conditions are shown with small vertical arrows to indicate increased or decreased expression. The documented action of sRNAs on selected targets or processes is indicated either with blocked lines (repression) or arrows (activation). The potential physiological effects of sRNA differential expression under chemical stress are shown with highlighting, where red indicates inhibition and blue indicates activation. Arrows from the sigma factors RpoE and RpoS indicate the sRNAs with sigma factor dependent expression. The blocked line and arrows from sRNAs to RpoS indicate sRNAs that target the rpoS mRNA and result in repression or activation of expression, respectively
