Partial suppression of pilA by cheW7-1. Agglutination (upper panels) and development (lower panels) were examined as described in Methods. Strains: DK1622 (wild-type); DK10407 (pilA); YZ1618 (pilA cheW7-1). No EPS production by either DK10407 or YZ1618 could be detected by dye binding (Supplementary Table S2).
