The lemon-shaped "virus-like" particle SSV1 produced by the thermophilic archaeon Sulfolobus shibatae has not previously been observed to infect any host. Using a plaque assay suitable for the extreme growth conditions of this archaeon, we have shown infection of Sulfolobus solfataricus by SSV1. Upon infection, the viral genome was always found integrated into a tRNA gene of the host chromosome, a situation similar to that in S. shibatae, proving that site-specific integration is involved in… Expand
Genetic requirements for the function of the archaeal virus SSV1 in Sulfolobus solfataricus: construction and testing of viral shuttle vectors.
The identification of otherwise cryptic crucial and noncrucial viral open reading frames in the genome of the archaeal virus SSV1 facilitated genetic analysis of this virus, and the shuttle vector should be useful for the development of genetic systems for Crenarchaeota. Expand
Elucidating the transcription cycle of the UV-inducible hyperthermophilic archaeal virus SSV1 by DNA microarrays.
Using whole-genome microarrays, it is shown that the circular 15.5 kb DNA genome of SSV1 exhibits a chronological regulation of its transcription upon UV irradiation, reminiscent to the life cycles of bacteriophages and eukaryotic viruses. Expand
Host-Dependent Differences in Replication Strategy of the Sulfolobus Spindle-Shaped Virus Strain SSV9 (a.k.a., SSVK1): Infection Profiles in Hosts of the Family Sulfolobaceae
It is shown that SSVs infect hosts representing more than one genus of the family Sulfolobaceae in spot-on-lawn “halo” assays and in liquid culture infection assays, and genetic elements, potentially resulting from allopatric evolution, mediate distinct virus-host growth profiles of specific SSV-host strain pairings.

Development of a genetic system for the archaeal virus Sulfolobus turreted icosahedral virus (STIV).
The development of an infectious clone allows for directed gene disruptions and detailed genetic analysis of the virus and was demonstrated by gene disruption of STIV open reading frame (ORF) B116 which resulted in crippled virus replication, while disruption of ORFs A197, C381 and B345 was lethal for virus replication.

The genetic element pSSVx of the extremely thermophilic crenarchaeon Sulfolobus is a hybrid between a plasmid and a virus
A new Sulfolobus islandicus strain, REY15/4, harboured both a novel fusellovirus, SSV2, and a small plasmid, pSSVx, which belonged to the family of pRN plasmids that share a highly conserved region, which probably constitutes the minimal replicon. Expand
PAV1, the First Virus-Like Particle Isolated from a Hyperthermophilic Euryarchaeote, “Pyrococcus abyssi”
The results suggest that PAV1 persists in the host strain in a stable carrier state rather than a prophages, and may contain lipids in addition to proteins. Expand
A novel Sulfolobus non-conjugative extrachromosomal genetic element capable of integration into the host genome and spreading in the presence of a fusellovirus.
Interestingly, pSSVi encodes an SSV-type integrase which probably catalyzes the integration of its genome into a specific site in the S. solfataricus P2 genome. Expand
Transfection of haloarchaea by the DNAs of spindle and round haloviruses and the use of transposon mutagenesis to identify non‐essential regions
This study shows that purified viral DNAs can transfect host cells and demonstrates that the cytoplasms of diverse haloarchaea possess all the factors necessary for viral DNA synthesis and virion assembly. Expand
A multicopy plasmid of the extremely thermophilic archaeon Sulfolobus effects its transfer to recipients by mating
A plasmid of 45 kb, designated pNOB8, was found in high copy number in a new heterotrophic Sulfolobus isolate, NOB8H2, from Japan, and horizontal transfer of pNob8 was proved by isolating transcipients from mating mixtures via single colonies. Expand
Characterization of the Sulfolobus host–SSV2 virus interaction
The findings of a comparative study of SSV2 physiology in the natural host, Sulfolobus islandicus REY15/4, versus the foreign host are reported and evidence of differently regulatedSSV2 life cycles in the two hosts is provided. Expand
