SlrR/SlrA controls the initiation of biofilm formation in Bacillus subtilis.

Abstract excerpt

SUMMARY: Undomesticated strains of Bacillus subtilis can form pellicle biofilms in standing culture. Pellicle formation is initiated by repression of flagellar genes and activation of the eps and yqxM operons, which are involved in biofilm-matrix synthesis. SinI is thought to induce the eps and yqxM operons by antagonizing their repressor SinR. Here, we show that mutations in late-flagellar genes prevent pellicle...
