hypermotility in Haloferax
December 31, 2020
Online today, Jan 1, 2021, a transposon-based study of genes involved in hypermotility in Hfx. volcanii by M. Collins et al., “Mutations Affecting HVO_1357 or HVO_2248 Cause Hypermotility in Haloferax volcanii, Suggesting Roles in Motility Regulation“. (Genes:12(1), 10.3390/genes12010058). Wonderful collaboration!
Two New HF1-like Haloviruses described
April 9, 2020
Serpecor1 and Hardycor2 are tailed viruses infecting the haloarchaeon Halorubrum coriense, and were recovered from widely separated hypersaline lakes in Australia way back in the late 1990s. They are similar to HF1 and add to an expanding group of viruses within a newly proposed genus Haloferacalesvirus. Read all about them in Genes at https://www.mdpi.com/2073-4425/11/4/405

Excellent paper just out by Zhou et al. describing exotic viruses of haloarchaea and nanohaloarchaea, and satellite plasmids (related to pL6-family plasmids).

Along with my ‘News and Views’ article about it.

What happens to Haloferax volcanii if you delete all of its resident proviruses? Read all about it here:

Just out, “DNA Replication in Time and Space: The Archaeal Dimension” by Anastasia Serdyuk and Thorsten Allers. The last paragraph of the discussion is thought provoking – even provocative!

Under pressure, haloarchaea stick together! See the paper by Rados et al. in Science

Microtubules in Asgard archaea! Nice study with excellent cyoEM and cryo-tomography pictures.
