Physiological consequences of DicF-xylR mRNA interactions. Physiological consequences of DicF-xylR mRNA interactions. (A) Schematic depicting regulatory interactions between DicF and xylR. The flattened arrowheads indicate translational repression of xylR and ftsZ by the indicated DicF RNAs. (B) ΔdicF lacIq strains harboring the Plac-vector or Plac-dicF, Plac-dicF3, or Plac-dicF9 were streaked on LB agar plates or M63 xylose plates with and without 0.5 mM IPTG. LB plates were incubated at 37°C for 12 h and M63 xylose plates for 22 h. Divya Balasubramanian et al. mSystems 2016; doi:10.1128/mSystems.00021-15
