PvrA contributes to the bacterial utilization of PC. Same amount of wild type PA14 and the ΔpvrA mutant were inoculated in Glu-M9 (A) and PC-M9 (B). The bacterial growth was monitored by measuring OD540. (C) PA14 and the ΔpvrA mutant were inoculated into Glu-M9 or PC-M9 and grown to an OD600 of 1.0. The relative mRNA levels of plcH, fadD1, fadD6 and PA0508 were determined by real time PCR. rpsL was used as the internal control. *P < 0.05; **P < 0.01; ***P < 0.001 by Student's t-test. Data represent the mean ± standard deviation from three samples.
