Live-Cell Visualization of DNA Transfer and Pilus Dynamics During Bacterial Conjugation

Methods Mol Biol. 2022:2476:63-74. doi: 10.1007/978-1-0716-2221-6_6.

Abstract

Bacterial genomes are highly plastic and evolve rapidly by acquiring new genetic information through horizontal gene transfer mechanisms. Capturing DNA transfer by conjugation between bacterial cells in real time is relevant to address bacterial genomes' dynamic architecture comprehensively. Here, we describe a method allowing the direct visualization of bacterial conjugation in live cells, including the fluorescent labeling of the conjugative pilus and the monitoring of plasmid DNA transfer from donor to recipient cells.

Keywords: Bacterial DNA conjugation; Conjugative pilus dynamics; DNA transfer dynamics; Horizontal gene transfer; Live-cell microscopy; Maleimide bioconjugation.
