Iron promotes wrinkling and matrix gene expression. (A) Colonies of the PtapA-lacZ-containing strain RL4582 grown on biofilm-inducing medium containing the indicated concentration of iron chloride. (B) PtapA-lacZ activity in pellicles of wild-type (RL4582) and sinR mutant (RL4585) cells grown in the presence of the indicated concentrations of iron chloride. (C) The growth of RL4582 in shaking liquid biofilm-inducing medium containing 5 μM (triangles), 50 μM (boxes), or 250 μM (diamonds) iron chloride, each grown in triplicate.
