Dual barcoded shotgun expression library sequencing, or Dub-seq, is a novel high-throughput method for discovering gene function in microbes under various environmental conditions. It was developed by scientists in the Environmental Genomics and Systems Biology (EGSB) Division under the aegis of the Ecosystems and Networks Integrated with Genes and Molecular Assemblies (ENIGMA) program. In a seminal paper published January 18 in Nature Communications, the Dub-seq team presented details of the technique and proof-of-concept work showing that the approach is reproducible, economical, scalable, and identifies both known and novel gene functions.
