Fig 4. BarA activates RcsB via its cognate response regulator SirA.
Fluorescence from wild-type (14028s), rcsB (EG12925), rcsC (HS1350), rcsD (HS1382), rcsC rcsD (HS1383), sirA (HS1565), sirA rcsC (HS1566), sirA rcsD (HS1567) and sirA rcsC rcsD (HS1568) Salmonella harboring plasmid pRprA-GFP (rprA-gfp) following 24 h of growth on LB solid medium without (-NaCl) or with (+NaCl) NaCl. Data are representative of two independent experiments, which gave similar results.
