3. ΔybeX cells exhibit severe sensitivity to sub-MIC
concentrations of cold-shock-inducing, ribosome-binding antibiotics.(A ) The wild-type (WT) and the ΔybeX cells were grown
overnight in LB liquid medium, serially diluted, and spotted on LB agar
plates supplemented with sub-MIC concentrations of indicated antibiotics
(No AB). The plates were incubated at 37°C overnight. (B )
Representative images are given from a dot spot assay with strains
described in Fig. 1. pYbeX denotes the YbeX-expressing TransBac library
plasmid.
