Fig. 4: Transcriptomics analysis of SOS, RpoS, and RpoH stress responses and of selected metabolic pathways.

RGB-S E. coli cells were treated with 2-propanol 2% (v/v) and sorted using FACS. Populations were sorted based on individual cell responses into four subpopulations, mono GFP, mono RFP, dual RFP-GFP, and triple RFP-GFP-BFP, with numbers (1, 2) indicating replicates. Differentially transcribed genes involved in SOS (a), RpoS (b), and RpoH (c) stress response pathways were analysed within the four sorted subpopulations. d Analysis of differentially transcribed metabolic pathways as annotated in the KEGG database of the four sorted subpopulations.
