Pleistocene glacial and interglacial ecosystems inferred from ancient DNA analyses of permafrost sediments from Batagay megaslump, East Siberia

Environmental DNA, Volume 4, Issue 6, Page 1265-1283, November 2022., 2022
As the past is the key to the future, to understand community transformations and ecological interactions, we reconstructed ecosystem‐wide biotic composition (from viruses to megaherbivores) between glacials and interglacials from the Middle and Late Pleistocene at the Batagay megaslump, east Siberia.

Ancient saltern metagenomics: tracking changes in microbes and their viruses from the underground to the surface

Environmental Microbiology, Volume 23, Issue 7, Page 3477-3498, July 2021., 2021
Summary Microbial communities in hypersaline underground waters derive from ancient organisms trapped within the evaporitic salt crystals and are part of the poorly known subterranean biosphere. Here, we characterized the viral and prokaryotic assemblages present in the hypersaline springs that dissolve Triassic‐Keuper evaporite rocks and feed the ...

Transkingdom network reveals bacterial players associated with cervical cancer gene expression program [PDF]

PeerJ, 2018
Cervical cancer is the fourth most common cancer in women worldwide with human papillomavirus (HPV) being the main cause the disease. Chromosomal amplifications have been identified as a source of upregulation for cervical cancer driver genes but cannot ...

The Structure of Evolutionary Model Space for Proteins across the Tree of Life

Biology, 2023
The factors that determine the relative rates of amino acid substitution during protein evolution are complex and known to vary among taxa. We estimated relative exchangeabilities for pairs of amino acids from clades spread across the tree of life and ...

Distribution of Archaeal Communities along the Coast of the Gulf of Finland and Their Response to Oil Contamination

Frontiers in Microbiology, 2018
The Baltic Sea is vulnerable to environmental changes. With the increasing shipping activities, the risk of oil spills remains high. Archaea are widely distributed in many environments.

Decoding the biological information contained in two ancient Slavonic parchment codices: an added historical value

Environmental Microbiology, Volume 22, Issue 8, Page 3218-3233, August 2020., 2020
Summary This study provides an example in the emerging field of biocodicology showing how metagenomics can help answer relevant questions that may contribute to a better understanding of the history of ancient manuscripts. To this end, two Slavonic codices dating from the 11th century were investigated through shotgun metagenomics.

Draft genome of Haloarcula rubripromontorii strain SL3, a novel halophilic archaeon isolated from the solar salterns of Cabo Rojo, Puerto Rico

Genomics Data, 2016
The genus Haloarcula belongs to the family Halobacteriaceae which currently has 10 valid species. Here we report the draft genome sequence of strain SL3, a new species within this genus, isolated from the Solar Salterns of Cabo Rojo, Puerto Rico.

Life at high salt concentrations, intracellular KCl concentrations, and acidic proteomes

Frontiers in Microbiology, 2013
Extremely halophilic microorganisms that accumulate KCl for osmotic balance (the Halobacteriaceae, Salinibacter) have a large excess of acidic amino acids in their proteins.
