ygjD-expression determines patterns of growth. Each panel depicts data of cell numbers versus time from three independent experiments; each experiment is based on a microcolony that was initiated with a single cell, and followed over about six to seven divisions. A) TB80 (Para-ygjD) grown in presence of 0.1% L-arabinose. B). TB80 (Para-ygjD) grown in presence of 0.4% glucose. Note that the growth rate decreased after about 150 minutes. C) MG1655 (E. coli wild type) grown in LB medium with additional 0.4% glucose. Growth rates are similar to panel A, indicating that the induction of ygjD-expression in TB80 (panel A) lead to growth rates that are similar to wild type E. coli.
