--- _id: '1342' abstract: - lang: eng text: A key aspect of bacterial survival is the ability to evolve while migrating across spatially varying environmental challenges. Laboratory experiments, however, often study evolution in well-mixed systems. Here, we introduce an experimental device, the microbial evolution and growth arena (MEGA)-plate, in which bacteria spread and evolved on a large antibiotic landscape (120 × 60 centimeters) that allowed visual observation of mutation and selection in a migrating bacterial front.While resistance increased consistently, multiple coexisting lineages diversified both phenotypically and genotypically. Analyzing mutants at and behind the propagating front,we found that evolution is not always led by the most resistant mutants; highly resistant mutants may be trapped behindmore sensitive lineages.TheMEGA-plate provides a versatile platformfor studying microbial adaption and directly visualizing evolutionary dynamics. author: - first_name: Michael full_name: Baym, Michael last_name: Baym - first_name: Tami full_name: Lieberman, Tami last_name: Lieberman - first_name: Eric full_name: Kelsic, Eric last_name: Kelsic - first_name: Remy P full_name: Chait, Remy P id: 3464AE84-F248-11E8-B48F-1D18A9856A87 last_name: Chait orcid: 0000-0003-0876-3187 - first_name: Rotem full_name: Gross, Rotem last_name: Gross - first_name: Idan full_name: Yelin, Idan last_name: Yelin - first_name: Roy full_name: Kishony, Roy last_name: Kishony citation: ama: Baym M, Lieberman T, Kelsic E, et al.
