Evolution of DNA ligases of Nucleo-Cytoplasmic Large DNA viruses of eukaryotes: a case of hidden complexity [PDF]

open access: yes, 2009
Background Eukaryotic Nucleo-Cytoplasmic Large DNA Viruses (NCLDV) encode most if not all of the enzymes involved in their DNA replication. It has been inferred that genes for these enzymes were already present in the last common ancestor of the NCLDV ...

In Silico Prophage Analysis of Halobacterium salinarum ATCC 33170

open access: yesApplied Microbiology
The extremophile Halobacterium salinarum is an aerobic archaeon that has adapted to thrive in high-salt environments such as salted fish, hypersaline lakes, and salterns. Halophiles have garnered significant interest due to their unique interactions with

Estudio de las virosferas de Salinibacter ruber y Haloquadratum walsbyi

open access: yes, 2021
Estudios en distintos ambientes, como el marino o el hipersalino, han demostrado que la combinación de metodologías y la integración de resultados tienen el potencial de aportar nueva información que las técnicas no pueden proveer de manera individual. En esta tesis se han utilizado tres cepas de S.

CRISPR-spacer integration reporter plasmids reveal distinct genuine acquisition specificities among CRISPR-Cas I-E variants of Escherichia coli [PDF]

open access: yes, 2013
Prokaryotes immunize themselves against transmissible genetic elements by the integration (acquisition) in clustered regularly interspaced short palindromic repeats (CRISPR) loci of spacers homologous to invader nucleic acids, defined as protospacers ...

Osmoadaptation mechanisms in prokaryotes: distribution of compatible solutes [PDF]

open access: yes, 2008
Microorganisms respond to osmotic stress mostly by accumulating compatible solutes, either by uptake from the medium or by de novo synthesis. These osmotically activ molecules preserve the positive turgor pressure required for cell division.

Characteristics of oligonucleotide frequencies across genomes: Conservation versus variation, strand symmetry, and evolutionary implications [PDF]

open access: yes, 2008
One of the objectives of evolutionary genomics is to reveal the genetic information contained in the primordial genome (called the primary genetic information in this paper, with the primordial genome defined here as the most primitive nucleic acid ...

Filogenia de los seres vivos: dominio Archaea [PDF]

open access: yes, 2017
A lo largo de la historia, la clasificación de los seres vivos ha ido variando en función de las diversas aportaciones científicas que se iban proponiendo, y la historia evolutiva de los organismos ha sido durante mucho tiempo algo que no se lograba ...

Discovery of salt-loving pleolipoviruses infecting archaea : vesicle-like virion is the key to success [PDF]

open access: yes, 2013
Extremophiles are found in all three domains of cellular life but especially archaea are able to withstand harsh conditions. Halophilic archaea thrive in hypersaline environments like salt lakes and salterns which have been shown to contain high ...

Microbiología ambiental y ecología microbiana en el estudio de microorganismos en ambientes extremos [PDF]

open access: yes, 2012
Se integrarán conceptos generales de ecología microbiana que permitan identificar diferentes microorganismos por medio de técnicas dependientes e independientes del cultivo en muestras ambientales de comunidades microbianas extremófilas.
