Med acts independently of KinC and in the same pathway as KinD to influence biofilm formation. Shown are biofilms formed by strains grown on solid MSgg medium that were either wild type (3610) or harbored a med mutation (AB349), a kinC mutation (AB399), a kinD mutation (RL4552), a kinC kinD mutation (AB401), a med kinC mutation (AB400), a med kinD mutation (AB351), P_hyperspank-med (AB396), a kinC mutation and P_hyperspank-med (AB402), or a kinC mutation and P_hyperspank-med (AB398). Expression of P_hyperspank-med was induced by addition of 1 mM (final concentration) IPTG to the medium.
