This book focuses on technologies used to study horizontal gene transfer (HGT) in prokaryotes. Beginning with a section on the detection and isolation of mobile genetic elements (MGEs), the volume continues with sections concentrating on the analysis of conjugation, transformation, and transduction in HGT as well as a series of methods to analyze the adaptation and evolution of MGEs, with special attention paid to bioinformatics tools. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical,
