FIG. 7.

Biofilm phenotypes of vpsR mutant and vpsR overexpression strains. Biofilms were produced upon disruption or overexpression of vpsR. (A) Colony morphology of vector (pKV69)-containing wild-type and vpsR mutant cells. (B) Crystal violet staining of glass-attached material from static cultures of wild-type or VFA0884 mutant cells carrying the vector control, pCLD42 (vpsR overexpressing), or pCLD29. (C) Pellicle formation by wild-type or VFA0884 mutant cells with vector, pCLD42, or pCLD29. Scores were assigned as described in Materials and Methods. Cells were grown as described in the legends for Fig. 2, 3, and 4.
