For years, researchers have known that many datasets miss a key part of microbial genomes: the mobile genetic elements, or MGEs, that can move between organisms. But now, deep sequencing and new analysis methods are bringing this mobilome into light, and opening up new options for engineering these microbes in the future. Join Sarah Bagby (Case Western Reserve University) and Simon Roux (JGI) as they talk about their recent work on a time series from Sweden’s Stordalen Mire.
