Single-celled bacteria can act independently to create patterns and structure in their biofilm communities!
Microbe of the episode:
Dictyostelium discoideum Skipper virus
In this study, bacteria growing in colonies on agar displayed a particular mechanism of pattern formation previously seen only in eukaryotes, called segmentation clock or clock and wavefront process. In this process, the cells in the colony are all acting individually without communication with each other, but nevertheless form a repeating ring structure in the colony as it grows, possibly allowing some measure of differentiation of cells that could help the community survive various challenges.
