In this study, rpoS gene was identified from Edwardsiella tarda EIB202 and its functional role was analyzed by using an in-frame deletion mutant ∆rpoS and the complemental strain rpoS +. Compared with the wild type and rpoS +, ∆rpoS was impaired in terms of the ability to survive under oxidative stress and nutrient starvation, as well as the resistance to 50% serum of Scophthalmus maximus in 3 h, demonstrating essential roles of RpoS in stress adaptation. The rpoS mutant also displayed markedly… CONTINUE READING
