Genetic techniques for the Archaea have undergone a rapid expansion in complexity, resulting in increased exploration of the role of Archaea in the environment and detailed analyses of the molecular physiology and information-processing systems in the third domain of life. Complementary gains in describing the ever-increasing diversity of archaeal organisms have allowed these techniques to be leveraged in new and imaginative ways to elucidate shared and unique aspects of archaeal diversity and metabolism. In this review, we introduce the four archaeal clades for which advanced genetic techniques are available—the methanogens, halophiles, , and —with the aim of providing an overall profile of the advantages and disadvantages of working within each clade, as essentially all of the genetically accessible archaeal organisms require unique culturing techniques that present real challenges. We discuss the full repertoire of techniques possible within these clades while highlighting the recent advances that have been made by taking advantage of the most prominent techniques and approaches.
