Molecular approaches that target the total DNA pool recovered from permanently anoxic marine ecosystems have revealed an extraordinary diversity of prokaryotes and unicellular eukaryotes. However, the presence of gene sequences contained within the extracellular DNA pool is still largely neglected. We have investigated the preservation, origin and genetic imprint of extracellular DNA recovered from permanently anoxic deep‐sea sediments of the Black Sea. Despite high DNase activities, huge… 

Preservation of microbial DNA in marine sediments: insights from extracellular DNA pools

The results indicate that in Aarhus Bay the vast majority of prokaryotic exDNA is turned over, thus not contributing to a genetic archive of past environmental change.

Extracellular DNA as a genetic recorder of microbial diversity in benthic deep-sea ecosystems

The findings expand the knowledge of the contribution of extracellular microbial sequences to current estimates of prokaryotic diversity obtained through the analyses of “environmental DNA”, and open new perspectives for understanding microbial successions in benthic ecosystems.

Preservation and Significance of Extracellular DNA in Ferruginous Sediments from Lake Towuti, Indonesia

It is concluded that extracellular DNA preserved in shallow lacustrine sediments reflects the initial environmental context, but is gradually modified and thereby shifts from its stratigraphic context.

Extracellular DNA can preserve the genetic signatures of present and past viral infection events in deep hypersaline anoxic basins

It is found that DHAB sediments are hot-spots of viral infections, which largely contribute to the release of high amounts of extracellular DNA, suggesting that extrace cellular DNA released from killed prokaryotes can be the most suitable trophic resource for benthic proKaryotes.

Origin, dynamics, and implications of extracellular DNA pools in marine sediments.

Ancient DNA complements microfossil record in deep-sea subsurface sediments

The potential of aDNA to better document the evolution of past marine ecosystems and opens new horizons for the development of deep-sea palaeogenomics is revealed.

Eukaryotic diversity in late Pleistocene marine sediments around a shallow methane hydrate deposit in the Japan Sea

The results suggest the long-term persistence of eukaryotic DNA from terrestrial and aquatic sources in marine sediments associated with cold seeps can be used to reconstruct environments and ecosystems from the past.

Deciphering the molecular signal from past and alive bacterial communities in aquatic sedimentary archives

The recovery of RNA in the present study has provided new insights into the origin of these signals, however, caution is required during analysis and interpretation of 16S gene metabarcoding data especially in recent sediments were there are potentially active bacteria.



Quantification, base composition, and fate of extracellular DNA in marine sediments

It is calculated that more than 50% of extracellular DNA was recalcitrant to enzymatic degradation, which might explain why DNA accumulates in surface sediments and suggests that DNA might play a nonnegligible role in P biogeochemical cycle.

Damage and degradation rates of extracellular DNA in marine sediments: implications for the preservation of gene sequences

It is suggested that the extracellular DNA pool in marine sediments represents a repository of genetic information, which can be used for improving the understanding of the biodiversity, functioning and evolution of ecosystems over different timescales.

Early diagenesis and trophic role of extracellular DNA in different benthic ecosystems

The data suggest that bioavailable extracellular DNA might represent an important nutrient source for benthic heterotrophic metabolism and open new perspectives for a better understanding of the factors that influence the functioning of benthics systems.

Viruses, prokaryotes and DNA in the sediments of a deep-hypersaline anoxic basin (DHAB) of the Mediterranean Sea.

The analysis of vertical profiles of viral abundance revealed the lack of significant changes with depth in the sediment, suggesting that benthic viruses in these anoxic and hypersaline conditions are preserved or resistant to decay.

Vertical distribution of metabolically active eukaryotes in the water column and sediments of the Black Sea.

The distribution of active eukaryotes (18S rRNA-based survey) along a vertical nutrient and redox gradient in the water column and surface sediments of the Black Sea indicates that gene transcripts do not always provide unequivocal proof that active microorganisms are indigenous to a specific position in an environmental gradient.

Significant contribution of Archaea to extant biomass in marine subsurface sediments

It is shown that in subsurface sediments buried deeper than 1 m in a wide range of oceanographic settings at least 87% of intact polar membrane lipids, biomarkers for the presence of live cells, are attributable to archaeal membranes, suggesting that Archaea constitute a major fraction of the biomass.

Quantification of microbial communities in near-surface and deeply buried marine sediments on the Peru continental margin using real-time PCR.

The occurrence of eukaryotic DNA also suggests DNA preservation in the deeply buried sediments, which reflects the ongoing degradation of the high-molecular-weight DNA with sediment age and depth.

Viral infection plays a key role in extracellular DNA dynamics in marine anoxic systems

Overall, the data suggest that DNA released by viral lysis, because of its high lability and fast turnover, may represent an important mechanism of trophic supply for prokaryotes, particularly in systems characterized by limited availability of external Trophic sources.

Autochthonous eukaryotic diversity in hydrothermal sediment and experimental microcolonizers at the Mid-Atlantic Ridge

A molecular survey based on 18S ribosomal RNA genes of eukaryotes present in different hydrothermal niches at the Mid-Atlantic Ridge identified considerable phylogenetic diversity, both at kingdom level and within kinetoplastids and alveolates.
