Effect of in trans protein expression on BDSF-regulated phenotypes. In trans expression of the encoding region of RpfR, the GGDEF, and EAL domains, and the EAL domain only in the BDSF synthase− mutant ∆rpfFBc rescued its phenotype defects in swarming motility (A), biofilm formation (B), and protease production (C). Data shown are means of two replicates and error bars indicate SDs.
