Mother cells inheriting old poles are phenotypically distinct and display increased drug efflux activity relative to daughters. Consequently, we find systematic and long-lived growth differences between mother and daughter cells in the presence of subinhibitory drug concentrations. A simple model for biased partitioning predicts a population structure of long-lived and highly heterogeneous phenotypes. This straightforward mechanism of generating sustained growth rate differences at subinhibitory antibiotic concentrations has implications for understanding the emergence of multidrug resistance in bacteria."}],"department":[{"_id":"CaGu"},{"_id":"GaTk"},{"_id":"Bio"}],"article_processing_charge":"No","title":"Biased partitioning of the multidrug efflux pump AcrAB TolC underlies long lived phenotypic heterogeneity","date_created":"2018-12-11T11:47:48Z","language":[{"iso":"eng"}],"publication_identifier":{"issn":["00368075"]},"intvolume":"       356","project":[{"call_identifier":"FWF","grant_number":"P28844-B27","_id":"254E9036-B435-11E9-9278-68D0E5697425","name":"Biophysics of information processing in gene regulation"}],"day":"21","page":"311 - 315","issue":"6335","month":"04","publication":"Science","citation":{"ama":"Bergmiller T, Andersson AM, Tomasek K, et al.
