Cross-reactivity heat map of nonspecific A activation and B inhibition of mCherry expression from investigated single-gene plasmids by different inducers. In the nonspecific activation test, nonspecific inducers were added to uninduced cultures, whereas in the nonspecific inhibition test, nonspecific inducers were added to induced cultures. Inducers concentrations were: 10 mM rhamnose, 1 mM IPTG, 10 mM arabinose, and 0.0025 mM m-toluic acid. Fluorescence values were normalised against the OD₆₀₀
