Dynamics of morphological evolution in experimental Escherichia coli populations

F. Cui, Yuan, B., Cui, F., and Yuan, B., Dynamics of morphological evolution in experimental Escherichia coli populations, vol. 15, p. -, 2016.

Here, we applied a two-stage clonal expansion model of morphological (cell-size) evolution to a long-term evolution experiment with Escherichia coli. Using this model, we derived the incidence function of the appearance of cell-size stability, the waiting time until this morphological stability, and the conditional and unconditional probabilities of morphological stability. After assessing the parameter values, we verified that the calculated waiting time was consistent with the experimental results, demonstrating the effectiveness of the two-stage model.
