From: Genomewide transcriptional response of Escherichia coli O157:H7 to norepinephrine
Determination of expression of genes encoding acid resistance pathway 2. Relative expression of gadB, hdeA, gadE and gadX genes was determined by using total RNA prepared from strain NADC 6564 grown without (green bars) or with norepinephrine (red bars). Error bars represent standard deviation of the mean of three independent assays. *** p = 0.00043, **** p = 0.000086; ** = p = 0.0037; **** p 0.000064
