Co-overexpression of tfoX and litR promotes transformation of KB2B1. Shown are transformation frequencies (Trimr CFU/viable CFU) of plostfoX-Cm- and pJJC4-containing KB2B1 strains exposed to gDNA from KV8300 (fliQ::Trim). Two of the three replicate samples of KB2B1 resulted in transformation frequencies below the LOD. ***, P < 0.0005.
