Cryo-EM resolves the structure of the archaeal dsDNA virus HFTV1 from head to tail This structure of an archaeal tailed virus (arTV) provides detailed insights into arTV assembly and infection mechanisms.

Out in Science Advances: Our #cryoEM structure of HFTV1, a virus infecting the halophile #archaea. *First full atomic structure (containing all structural proteins) of any tailed virus!* Congrats and thanks to all co-authors and our fantastic collaborators! www.science.org/doi/10.1126/...

Filamentous growth, cell envelope architecture, and surface appendages of a member of the Chloroflexota, Litorilinea aerophila Litorilinea aerophila , a filamentous bacterium of the phylum Chloroflexota (class Caldilineae ), exhibits unique morphological and cell envelope features that challenge traditional bacterial models. ...

Yes, indeed, we were surprised, too! But we hypothesize that it only works because of the cell envelope structure of these Chloroflexota strains, see also here:

Thanks, Dina!
It is still clear that only very few bacteria seem to have an archaellum, and so far, there are no flagella in archaea, so for now, I think we are good ๐Ÿ˜€

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...

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...
