Sulfolobus species belong to the best-studied archaeal organisms but have lacked powerful genetic methods. Recently, there has been considerable progress in the field of Sulfolobus genetics. Urgently needed basic genetic tools, such as targeted gene knockout techniques and shuttle vectors are being developed at an increasing pace. For S. solfataricus knockout systems as well as different shuttle vectors are available. For the genetically more stable S. acidocaldarius shuttle vectors have been recently developed. In this review we summarize the currently available genetic tools and methods for the genus Sulfolobus. Different transformation protocols are discussed, as well as all so far developed knockout systems and Sulfolobus-Escherichia coli shuttle vectors are summarized. Special emphasis is put on the important vector components, i.e., selectable markers and Sulfolobus replicons. Additionally, the information gathered on different Sulfolobus strains with respect to their use as recipient strains is reviewed. The advantages and disadvantages of the different systems are discussed and aims for further improvement of genetic systems are identified.
