From: Synergistic action of SPI-1 gene expression in Salmonella enterica serovar typhimurium through transcriptional crosstalk with the flagellar system

Fig. 2

Acetate and yeast extract (YE) synergistically induce expression from the hilA promoter during growth in TB medium. Expression from hilA promoter was determined using single-copy transcriptional fusions to GFP as determined using flow cytometry. hilA promoter activity in wild-type cells during: growth in TB medium (a); growth in TB medium containing 1% NaCl (b); and growth in TB medium containing 10 mM sodium acetate (c) at various concentrations of yeast extract. Negative control (NC) is the measured fluorescence of wild-type cells not containing the gfp gene during growth in TB medium. Analysis of data is provided in Fig. 3
