From: Antagonistic autoregulation speeds up a homogeneous response in Escherichia coli
Single-cell dynamics of the mar response upon induction.
(A) The image shows a subset of lineages with different YFP expression levels upon induction with 5 mM salicylate. On the right, variation in response time (t50) is quantified among 60 different lineages within the population. (B) Graded transcriptional activation of the mar phenotype, measured as the ratio YFP/CFP, in a growing population of single cells (histograms at different times illustrate the relatively homogeneous response). Solid line is the model simulation, considering a delay in expression.
