Expression of the regulators rpoS (A) and oxyR (B) in different strains of Vibrio parahaemolyticus under VBNC-inducing conditions. V. parahaemolyticus strains in the exponential phase were incubated at 4°C in MMS–0.5% NaCl medium. Relative quantities of rpoS and oxyR transcripts in different strains were determined by RT-qPCR, and the calculated quantities were compared to those in exponential phase, specified as −1 week in the graph and presented on a log scale. Filled arrows indicate times to entry into the VBNC state, while open arrows indicate the times after which the VBNC cells failed to be resuscitated.
