Transposon insertion mutagenesis

Transposon insertion mutagenesis is a forward genetic approach that has been widely utilized for genetic characterization of bacteria and single-celled eukaryotes, and its applications are being rapidly expanded into a few archaeal model organisms for gene function analysis. Previously, we developed a Tn5-based in vivo transposon insertion mutagenesis system in the hyperthermophilic crenarchaeon S. islandicucs M.16.4 and defined the essential gene set under laboratory growth conditions. In this chapter, we will mainly focus on presenting details regarding the generation of a near-saturating transposon insertion mutant library in this crenarchaeal model. We envision that the traditional transposon-based forward mutagenesis screening paired with next generation sequencing will greatly speed up the exploration of archaeal genomic features.
