Motility in Archaea is driven by a nanomachinery called the archaellum. So far, archaella have been exclusively described for the archaeal domain; however, a recent study reported the presence of arch...

This research enhances our knowledge of toxin-antitoxin (TA) systems in archaea, specifically in the thermoacidophilic archaeon Sulfolobus acidocaldarius. TA systems are widespread in both bacterial and archaeal genomes, indicating their evolutionary ...

In the cells of Sulfolobales, the Ced (Crenarchaeal system for exchange of DNA) and Ups (UV- inducible pili of Sulfolobus) systems are highly induced by DNA damages and function in chromosomal DNA exc...

After exposure to UV light, Sulfolobus acidocaldarius cells aggregate in a species-specific manner to exchange DNA and repair double-strand breaks via homologous recombination. The formation of cell-c...
