Knockdown extent affects the sign of antibiotic-gene interactions. (A-B) Schematics of idealized dose-response curves showing monotonic or hormetic relationships between dose and response; hormetic responses change the sign of the response depending on dose. (C-D) Knockdown-response curves of glnS show a nearly monotonic response in the absence of IMI, but a hormetic response in the presence of IMI. (E) The interaction between the IleRS tRNA synthetase inhibitor mupirocin (MUP) and IMI shows a hormetic response at intermediate concentrations of IMI.
