Sonication Extraction of Lipid Biomarkers from Sediment

Source: Laboratory of Jeff Salacup - University of Massachusetts Amherst
The material comprising the living "organic" share of any ecosystem (leaves, fungi, bark, tissue; Figure 1) differs fundamentally from the material of the non-living "inorganic" share (rocks and their constituent minerals, oxygen, water, metals). Organic material contains carbon linked to a series of other carbon and hydrogen molecules (Figure 2), which distinguishes it from inorganic material. Carbon's wide valency range...

Complement System01:27

Complement System

9.8K
The complement system is a group of approximately 20 plasma proteins that strengthen the body's defenses against infections through opsonization, inflammation, and cell lysis. Opsonization involves coating pathogens with complement proteins, making them more recognizable and facilitating phagocyte engulfment. Certain complement proteins induce inflammation that attracts immune cells to the site of infection. Cell lysis involves the destruction of pathogens through the formation of a...

Area of Science:

  • Marine biology
  • Paleogenomics
  • Geology

Background:

  • Deep-sea sediments are crucial archives of marine biodiversity.
  • Traditional studies rely on microfossils, overlooking abundant DNA.
  • Ancient DNA (aDNA) offers insights into both fossilized and non-fossilized marine taxa.

Purpose of the Study:

  • To investigate the preservation and utility of eukaryotic aDNA in deep-sea sediments.
  • To compare ancient DNA assemblages with microfossil records for Foraminifera and Radiolaria.
  • To explore the potential of aDNA for reconstructing past marine biodiversity and ecosystems.

Main Methods:

  • Collection of sediment cores from abyssal depths in the South Atlantic.
  • Application of micropalaeontological analysis.
  • Environmental DNA sequencing targeting eukaryotic aDNA, specifically the small subunit rRNA gene of Foraminifera and Radiolaria.

Main Results:

  • Successful recovery of eukaryotic aDNA from sediment layers up to 32.5 thousand years old, including the Last Glacial Maximum.
  • aDNA sequences were primarily assigned to non-fossilized taxa, mirroring modern molecular studies.
  • Co-occurrence of micropalaeontological and aDNA data provides a more comprehensive view of past marine life.

Conclusions:

  • Eukaryotic aDNA is well-preserved in deep-sea sediments, offering a valuable historical record.
  • aDNA analysis significantly enhances the documentation of past marine biodiversity, especially for non-fossilized organisms.
  • This study establishes a foundation for deep-sea paleogenomics, revolutionizing our understanding of marine ecosystem evolution.
