Genomic DNA in Prokaryotes

Genomic DNA in Prokaryotes

The genome of most prokaryotic organisms consists of double-stranded DNA organized into one circular chromosome in a region of cytoplasm called the nucleoid. The chromosome is tightly wound, or supercoiled, for efficient storage. Prokaryotes also contain other circular pieces of DNA called plasmids. These plasmids are smaller than the chromosome and often carry genes that confer adaptive functions, such as antibiotic resistance.

Modern Molecular Taxonomy

Advancements in molecular biology have revolutionized the identification and characterization of bacteria, with multiple methods leveraging DNA sequencing for enhanced precision. As sequencing technologies improve and costs decline, these approaches are increasingly used in clinical, environmental, and evolutionary studies.Multilocus Sequence Typing (MLST) examines several housekeeping genes, essential chromosomal genes encoding cellular functions, to distinguish strains. Approximately...

Genomic DNA in Eukaryotes

Genomic DNA in Eukaryotes

Eukaryotes have large genomes compared to prokaryotes. To fit their genomes into a cell, eukaryotic DNA is packaged extraordinarily tightly inside the nucleus. To achieve this, DNA is tightly wound around proteins called histones, which are packaged into nucleosomes that are joined by linker DNA and coil into chromatin fibers. Additional fibrous proteins further compact the chromatin, which is recognizable as chromosomes during certain phases of cell division.

Area of Science:

Microbiology
Genomics
Biogeochemistry

Background:

Cold seeps are vital microbial ecosystems influencing global biogeochemical cycles.
Existing metagenomic studies offer insights but lack comprehensive global diversity and genetic data.

Purpose of the Study:

To construct a comprehensive gene and genome catalog of global cold seep microbes.
To identify novel microbial species and their genetic repertoire in cold seeps.

Main Methods:

Compiled 165 metagenomic datasets from 16 global cold seep sites.
Constructed a non-redundant gene catalog and generated metagenome-assembled genomes (MAGs).

Main Results:

Created a gene catalog of 147 million genes, with 36% unassigned functions.
Obtained 3,164 species-level MAGs, with 94% representing novel species.
Identified 81 archaeal anaerobic methanotrophic (ANME) and 23 syntrophic sulfate-reducing bacteria (SRB) species.

Conclusions:

The developed catalog provides a valuable resource for studying cold seep microbiome functions.
This work significantly expands the known diversity and genetic potential of cold seep microbial communities.
