AbstractPeriodic stripe patterns are ubiquitous in living organisms, yet the underlying developmental processes are complex and difficult to disentangle. We describe a synthetic genetic circuit that couples cell density and motility. This system enabled programmed Escherichia coli cells to form periodic stripes of high and low cell densities sequentially and autonomously. Theoretical and experimental analyses reveal that the spatial structure arises from a recurrent aggregation process at the front of the continuously expanding cell population. The number of stripes formed could be tuned by modulating the basal expression of a single gene. The results establish motility control as a simple route to establishing recurrent structures without requiring an extrinsic pacemaker.

Funding Information:

We are grateful to members of the University of Hong Kong Team for The International Genetic Engineering Machine Competition (iGEM) 2008 for their contribution to the project. We thank H. Berg, A. Courey, A. Danchin, D. Smith, J. Tailleur, and C. Voigt for valuable comments. This project was supported by a Hong Kong University (HKU) University Development Fund, a Small Project Grant from the HKU Committee on Research and Conference Grants, and a Collaborative Research Fund from the Research Grants Council (RGC) (HKU1/CRF/10) to J.D.H., and a HKU Faculty of Medicine Development Fund to W.H. TH is supported by the NSF through the Center for Theoretical Biological Physics (grant PHY-0822283) and additionally acknowledges an HKU Distinguished Visiting Professorship. P.L. acknowledges support through the LOEWE program of the State Hessen. L.H.T. acknowledges support by the RGC of the Hong Kong Special Administrative Region under grant 201606. E. coli strains and plasmids are available under a material transfer agreement with the University of Hong Kong.
