Figure Lengend Snippet: A sudden temperature increase causes transcript levels to change up to ~ 71-fold. (A) Volcano plot showing the differentially expressed genes (DEGs) for the heat-shock experimental condition with |log2 FC| ≥ 1.5 and adjusted p ≤ 0.05 as the threshold. The red dots represent 235 significantly upregulated genes, and the blue dots represent 131 significantly downregulated genes. (B) Summary of the significantly upregulated and downregulated genes during the heat-shock response in S. epidermidis assigned to functional groups according to GO and KEGG pathways (in %).

Figure Lengend Snippet: Eighty-five S. epidermidis genes change expression levels in response to glucose. (A) Circular transcriptome map showing normalized gene expression levels in the S. epidermidis genome in response to glucose. Log2 fold change relative to control for cells exposed to 2 mM (G2), 5 mM (G5), 10 mM (G10), 17 mM (G17), or 50 mM (G50) glucose spikes. Each bar denotes a single gene; red bars represent significantly upregulated genes and blue bars represent significantly downregulated genes. Roman numerals i ( sdaAB , rbsU ), ii ( pflB ), iii ( glpR-pfkB operon), iv (F1613_RS07845 (homoserine dehydrogenase), and v (members of the lac operon) correspond to select groups of genes that are downregulated across all five glucose spike conditions. (B) Glucose concentration-response curves for a representative subset of genes that have potentially interesting glucose-responsive switch properties.

Figure Lengend Snippet: The genome-wide transcription response of S. epidermidis to perturbations. Circular transcriptome map showing normalized gene expression levels in the S. epidermidis genome. Log2-fold change relative to control for cells exposed to Heat Shock (HS), a 17 mM glucose spike (G17), or Step Down (SD) experimental conditions. Each bar denotes a single gene. The red bars represent significantly upregulated genes, and the blue bars represent significantly downregulated genes.
