Figure 6. Relative expression of pobA in the presence of radish hydrolates (RHs) or cabbage hydrolates (CHs).

Figure 6

(a) The dose-dependent pobA expression in the wild-type strain XC1 in the presence of 0.1–100 mg/L phenolic compounds. (b) The relative pobA expression in the strains of XC1 and ΔpobR. (c) The extracted ion chromatograms of standards 2-HBA, 3-HBA and 4-HBA at 50 μM. (d) The extracted ion chromatograms of 2-HBA, 3-HBA and 4-HBA in radish hydrolysates. Total RNA was extracted from the cultures 3 h after addition of the hydrolates. The relative levels of pobA were determined by quantitative real-time RT-PCR. Data are expressed as the means ± standard deviation of three independent assays.
