RpoS-Dependent Mechanisms are Needed for Tetracycline Resistance but Are Not Involved in the Cross-Protection against Other Antibiotics in Escherichia coli

RpoS, an alternate sigma subunit of RNA polymerase, is upregulated under stress conditions such as high heat, depletion of nutrient, high osmolarity, and UV radiation. Current understanding is that RpoS acts as a general stress response regulator to counter the effect of differen...
