Standards in Genomic Sciences
|December 20, 2011
Summary
Open resource metagenomics proposes sharing physical DNA libraries, like the Canadian MetaMicroBiome Library, to advance microbial research. This open access approach facilitates broader scientific discovery and collaboration.
Area of Science:
- Microbial Genomics
- Metagenomics
- Biotechnology
Background:
- Environmental DNA (eDNA) analysis offers extensive genomic insights into microorganisms.
- Current practices often limit access to physical metagenomic libraries post-publication.
- A need exists for accessible, shareable metagenomic resources.
Purpose of the Study:
- To propose and establish an open resource model for metagenomics.
- To facilitate unrestricted distribution and utilization of physical metagenomic libraries.
- To promote a paradigm shift towards open access in functional metagenomics.
Main Methods:
- Development of a concept for open resource metagenomics.
- Creation of physical DNA libraries in versatile vectors for broad host compatibility.
- Establishment of the Canadian MetaMicroBiome Library (CM(2)BL) with pooled cosmid libraries.
- Public deposition of associated metadata and sequence data.
Main Results:
- The Canadian MetaMicroBiome Library (CM(2)BL) has been established as a publicly accessible collection.
- Libraries contain environmental DNA from diverse Canadian soil biomes.
- Cloned DNA is transferable to Gateway® compliant vectors for functional screening.
Conclusions:
- Open resource metagenomics enhances the utility of functional metagenomic data beyond initial studies.
- This model supports collaborative research and reduces redundancy in scientific endeavors.
- Adoption of open resource principles will accelerate discoveries in microbial genetics and related fields.

02:02Genomics
Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...
02:54Evolutionary Relationships through Genome Comparisons
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...
01:08Evolution of Microbial Genome
Microbial genome evolution is a highly dynamic process shaped by continual gene gain and loss across species and strains. This genomic flexibility allows microorganisms to adapt rapidly to environmental pressures and interactions with other organisms. Central to understanding this diversity is the distinction between the core and pan genomes.The core genome comprises the genes shared by all sampled strains of a species, representing essential functions needed for fundamental cellular processes.
00:46Genomic 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.
