Differentiation and Structure in Sulfolobus islandicus Rod-Shaped Virus Populations
In the past decade, molecular surveys of viral diversity have revealed that viruses are the most diverse and abundant biological entities on Earth. In culture, however, most viral isolates that infect microbes are represented by a few variants isolated on type strains, limiting our ability to study how natural variation affects virus-host interactions in the laboratory. We screened a set of 137...
متن کاملThe Effects of Temperature and Growth Phase on the Lipidomes of Sulfolobus islandicus and Sulfolobus tokodaii
The functionality of the plasma membrane is essential for all organisms. Adaption to high growth temperatures imposes challenges and Bacteria, Eukarya, and Archaea have developed several mechanisms to cope with these. Hyperthermophilic archaea have earlier been shown to synthesize tetraether membrane lipids with an increased number of cyclopentane moieties at higher growth temperatures. Here we...
متن کاملThe replication protein of the Sulfolobus islandicus plasmid pRN1.
The thermoacidophile crenarchaeote Sulfolobus ssp. is one of the best-studied Archaea. Cryptic and conjugative plasmids as well as viruses have been described for this genus. For the majority of the genetic elements only the genome sequence and the basic characteristics were determined. In contrast the fusellovirus SSV1 and the cryptic plasmid pRN1, which is the smallest known genetic element o...
متن کاملVirus-Induced Dormancy in the Archaeon Sulfolobus islandicus
UNLABELLED We investigated the interaction between Sulfolobus spindle-shaped virus (SSV9) and its native archaeal host Sulfolobus islandicus. We show that upon exposure to SSV9, S. islandicus strain RJW002 has a significant growth delay where the majority of cells are dormant (viable but not growing) for 24 to 48 hours postinfection (hpi) compared to the growth of controls without virus. We dem...
متن کاملCRISPR Associated Diversity within a Population of Sulfolobus islandicus
BACKGROUND Predator-prey models for virus-host interactions predict that viruses will cause oscillations of microbial host densities due to an arms race between resistance and virulence. A new form of microbial resistance, CRISPRs (clustered regularly interspaced short palindromic repeats) are a rapidly evolving, sequence-specific immunity mechanism in which a short piece of invading viral DNA ...
