Would you expect that Bacteria use an archaellum for swimming? We didn't, but we found that some Chloroflexota do! Find the story here: www.biorxiv.org/content/10.1...

A little thread below 1/n
Horizontal gene transfer of the functional archaellum machinery to Bacteria
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...

The story is finally out!!! Here, we showed multiple functions of the VapBC4 toxin-antitoxin of Sulfolobus acidocaldarius under stress. Thanks to @archaellum.bsky.social for an excellent collaboration.

Role of VapBC4 toxin-antitoxin system of Sulfolobus acidocaldarius in heat stress adaptation | mBio
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 ...

Our latest pre print is out! We (@marleenvw.bsky.social @sshamphavi.bsky.social at @archaellum.bsky.social lab) studied up regulated genes in UV-stress and found two new components of the Ups pili and the fascinating Ced system in Sulfolobales #ArchaeaSky #MicroSky

New components of the community based DNA-repair mechanism in Sulfolobales
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...
