Modulation of the PifC-mediated FI of R388 by overexpression of the coupling protein. Each point represents the conjugation frequency (T/D) of one independent experiment, in the presence or absence of pOX38 and R388 coupling protein TrwB. Horizontal and vertical bars represent the mean ± SD obtained for each group of data (***p < 0.001). None/- (indicated by yellow circles), R388 alone. None/pBAD33::trwB (yellow circles), R388 in the presence of pBAD33::trwB. pOX38/- (blue squares), R388 in the presence of pOX38::KmR. pOX38/pBAD33 (blue squares), R388 in the presence of pOX38::KmR and pBAD33 empty vector. pOX38/pBAD33::trwB (orange squares), R388 in the presence of pOX38::KmR and pBAD33::trwB.
