Relative mRNA levels of indicated genes in indicated strains. (A) Relative mRNA levels of ampC in indicated strains. (B) Relative mRNA levels of pbpC in indicated strains. (C) Relative mRNA levels of armR in ISP50 and IRP41. (D) Relative mRNA levels of mexB in ISP50 and IRP41. Total RNA was isolated from indicated strains at OD600 of 1.0, and the relative mRNA levels of indicated genes were determined by real-time qPCR using rpsL as an internal control. ns, not significant, ****P < 0.0001, by Student’s t-test.
