A. An image of a microcolony containing the plasmid-borne fliC promoter driving expression of GFP. The colony was started from a single cell and grown for about 6 generations. B. A lineage tree of this microcolony with GFP expression plotted in green (light colored boxes represent high levels of GFP, and dark boxes represent low levels), illustrating the temporal pattern of switching of the fliC promoter. The image and the lineage tree are based on Movie S1.
