Gene expression of msa and sarA in the msa mutant or the complemented mutant (Compl.) relative to wild-type (COL). Values represent the mean ratio of three independent experiments. Expression measurements were done in biofilm and three planktonic growth phases (mid-exponential, late-exponential and post-exponential).
