Polyploidy in haloarchaea: advantages for growth and survival
The investigated haloarchaeal species, Halobacterium salinarum, Haloferax mediterranii, and H. volcanii, have all been shown to be polyploid. They contain several replicons that have independent copy number regulation, and most have a higher copy number ...

DNA damage induces nucleoid compaction via the Mre11-Rad50 complex in the archaeon Haloferax volcanii [PDF]
In prokaryotes the genome is organized in a dynamic structure called the nucleoid, which is embedded in the cytoplasm. We show here that in the archaeon Haloferax volcanii, compaction and reorganization of the nucleoid is induced by stresses that ...

DNA replication origins in Haloferax volcanii [PDF]
DNA replication is fundamental to the proliferation of life. Sites of DNA replication initiation are called replication origins. Bacteria replicate from a single origin whereas eukaryotes utilise multiple origins for each chromosome. The archaeal domain includes species which replicate using multiple origins of replication in addition to those which ...

An emerging phylogenetic core of Archaea: phylogenies of transcription and translation machineries converge following addition of new genome sequences [PDF]
Background The concept of a genomic core, defined as the set of genes ubiquitous in all genomes of a monophyletic group, has become crucial in comparative and evolutionary genomics.

Regulation der Translation in Haloferax volcanii [PDF]
Im Rahmen dieser Arbeit wurden ausgewählte 5’- und 3’-untranslatierte Regionen (UTRs) von mRNAs aus H. volcanii bestimmt. Dieses Datenset wurde verwendet um (1) haloarchaeale UTRs zu charakterisieren, (2) Konsensuselemente für die Transkrikptionsinitiation und -termination zu verifizieren und (3) den Einfluss haloarchaealer UTRs auf die Initiation und ...

Laboratory Activity to Promote Student Understanding of UV Mutagenesis and DNA Repair
Changes in DNA molecules are common, due to the effects of UV light and other external and internal mutagens. Cells have a variety of repair mechanisms which serve to maintain the accuracy of the genetic code.

Prozessierung stabiler RNAs im Archaeon Haloferax volcanii
The RNA metabolism in kingdoms bacteria and eukarya is well studied, whereas the mechanisms in archaea are still not well understood. The goal of this study was to find new endonucleolytic RNases for RNA precursor processing and maturation in archaea. The following two approaches were applied: An in vitro approach for the identification of new RNases ...

Haloferax volcanii is a well-established model species for haloarchaea. Small scale RNomics and bioinformatics predictions were used to identify small non-coding RNAs (sRNAs), and deletion mutants revealed that sRNAs have important regulatory functions ...

Comparative functional genomics approach for the annotation of proteins in Unclassified Halophilic archaeon DL31 [PDF]
The structure, function and sub-cellular location prediction for the unknown proteins from Unclassified Halophilic archaeon DL31 were carried out for characterization of the proteins in their respective families.
