Survey of high-resolution archaeal virus structures
Current Opinion in Virology, 2019Archaeal viruses exhibit diverse morphologies whose structures are just beginning to be explored at high-resolution. In this review, we update recent findings on archaeal structural proteins and virion architectures and place them in the biological context in which these viruses replicate.

Unique genome replication mechanism of the archaeal virus
SummaryThe exceptional genomic content and genome organization of the Acidianus filamentous virus 1 (AFV1) that infects the hyperthermophilic archaeon Acidianus hospitalis suggest that this virus might exploit an unusual mechanism of genome replication.

Abstract Archaeal head-tailed viruses appear, at first sight, very closely related to head-tailed bacteriophages simply due to morphological similarities and similar life cycles. However, they encounter host cells that are very different from bacteria and share characteristics, that greatly influence virus life cycles,

Investigation of a putative toxin-antitoxin system of the archaeal virus ΦCh1
2018Der temperente Virus ΦCh1 infiziert das haloalkaliphile Archeon Natrialba magadii. Eine Untersuchung des offenen Leserahmens 44 (ORF44) zeigte in der Pfam Datenbank, dass ORF44 eine „PilT N terminal domain” (PIN-Domäne) enthält. Dieser bildet zusammen mit ORF43 ein Operon, da sie co-transkripiert und co-translatiert wird.

Isolation and characterization of hyperthermophilic archaeal virus-host systems
Isolation et caractérisation de systèmes viraux-hôtes d'archées Les virus infectant les archées présentent des morphotypes inhabituels et des génomes extrêmement divers. Leur isolation a permis de développer nos connaissances sur la diversité de la virosphère et demeure une piste de recherche primordiale.openaire +1 more source
A new archaeal virus that suppresses the transcription of host immunity genes
Abstract In some extreme environments, archaeal cells have been shown to have chronic viral infections, and such infections are well-tolerated by the hosts and may potentially protect against more lethal infections by lytic viruses. We have discovered that a natural Haloferax strainIsraela Turgeman-Grott +11 more

Unraveling the archaeal virosphere: diversity, functional and virus-host interactions
Abstract Archaea, the third domain of life, play critical roles in global biogeochemical cycles. However, their virosphere, particularly the proviruses which integrated into host genomes, remains largely unexplored. To systematically reveal the landscape of archaeal proviruses, we conducted large-scale mining of public and in-house ...Yang Zhao +7 more
