The paper presents high-quality chromosome-level genomes of 39 haloarchaeal strains, expanding genomic resources and enabling comparative studies of archaeal biology and virus-host interactions.

The paper analyzes viral diversity and functional potential in polar and subarctic sea ice metagenomes, identifying common auxiliary metabolic genes and host interactions.

This study identifies and characterizes cinquedea, a bactericidal phospholipase from the archaeon Haloferax larsenii that kills halophilic bacteria by damaging their cell membranes.

This study identifies antiviral defense systems in haloarchaea and finds that hosts with more defense systems are less susceptible to viral infection, while receptor availability primarily determines host range.

The paper isolates 40 bacteriophages from boreal and subarctic freshwaters, identifying eight jumbophages with novel genomic features and ecological roles.

This study uses cryo-EM to determine the near-atomic structure of the archaeal virus HFTV1, revealing insights into its assembly, infection mechanisms, and host-virus interactions.
