FIG. 8.

Schematic of morphotypic cycling of KM'92 during biofilm and broth growth. Arrows indicate the direction and the condition that mediates morphotypic change (biofilm formation, black arrows; broth culture, grey arrows). The thickness of the arrow denotes the relative frequency of morphotypic conversion (thin, rarely observed; thick, commonly observed). The conditions for the direct conversion between wild type and LR or RS to wild type (dotted arrows) have yet to be identified. Circular arrows show the relative stability of the wild type in broth and of LR in biofilms.
