{"status":"public","volume":6,"title":"Complex chromosomal neighborhood effects determine the adaptive potential of a gene under selection","abstract":[{"text":"How the organization of genes on a chromosome shapes adaptation is essential for understanding evolutionary paths. Here, we investigate how adaptation to rapidly increasing levels of antibiotic depends on the chromosomal neighborhood of a drug-resistance gene inserted at different positions of the Escherichia coli chromosome. Using a dual-fluorescence reporter that allows us to distinguish gene amplifications from other up-mutations, we track in real-time adaptive changes in expression of the drug-resistance gene. We find that the relative contribution of several mutation types differs systematically between loci due to properties of neighboring genes: essentiality, expression, orientation, termination, and presence of duplicates. These properties determine rate and fitness effects of gene amplification, deletions, and mutations compromising transcriptional termination. Thus, the adaptive potential of a gene under selection is a system-property with a complex genetic basis that is specific for each chromosomal locus, and it can be inferred from detailed functional and genomic data.","lang":"eng"}],"file":[{"checksum":"6b908b5db9f61f6820ebd7f8fa815571","file_size":2092088,"access_level":"open_access","relation":"main_file","date_updated":"2020-07-14T12:47:48Z","file_name":"IST-2017-890-v1+1_elife-25100-v1.pdf","content_type":"application/pdf","date_created":"2018-12-12T10:12:54Z","file_id":"4975","creator":"system"},{"creator":"system","file_id":"4976","date_created":"2018-12-12T10:12:55Z","file_name":"IST-2017-890-v1+2_elife-25100-figures-v1.pdf","content_type":"application/pdf","date_updated":"2020-07-14T12:47:48Z","relation":"main_file","file_size":3428681,"access_level":"open_access","checksum":"ca21530389b720243552678125fdba35"}],"file_date_updated":"2020-07-14T12:47:48Z","citation":{"short":"M.
