Summary
Next-generation sequencing technologies are revolutionizing ecology and evolution studies by enabling cost-effective, large-scale genome sequencing. This advancement allows for deeper insights into population genetics and the genomics of diverse species.
Area of Science:
- Ecology and Evolutionary Biology
- Genomics
- Bioinformatics
Background:
- Whole-genome and whole-population sequencing (metagenomics) are transforming ecological and evolutionary research.
- Current applications are most advanced in Bacteria and Archaea; broader eukaryotic application requires more sequence data.
- Next-generation sequencing (NGS) technologies offer practical, cost-effective, and high-throughput sequencing solutions.
Purpose of the Study:
- To review new high-throughput sequencing technologies.
- To discuss their limitations and applicability to evolutionary and environmental studies.
- To highlight the potential of NGS for advancing genomic ecology.
Main Methods:
- Review of next-generation sequencing technologies: 454 pyrosequencing, Solexa/Illumina, polony sequencing, and AB SOLiD.
- These methods utilize nanotechnology for massively parallel sequencing, generating numerous small sequence reads.
- Focus on practical, lower-cost sequencing without large, automated facilities.
Main Results:
- NGS technologies enable genome and transcriptome sequencing/resequencing for more projects and species.
- Potential to extend the genomics revolution to entire populations and diverse organisms, including endangered species.
- Facilitates genome-level population genetic studies in wild populations.
Conclusions:

03:00Next-generation Sequencing
The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.
Next-Generation Sequencing Methods
Although all next-generation methods use different technologies, they all share a set of standard features.

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...
01:05Maxam-Gilbert Sequencing
In the same year as the discovery of the Sanger sequencing method, another group of scientists, Allan Maxam and Walter Gilbert, demonstrated their chemical-cleavage method for DNA sequencing. The Maxam-Gilbert method relies on using different chemicals that can cleave the DNA sequence at specific sites, the separation of resulting DNA fragments of variable size using electrophoresis, and deciphering the DNA sequence from the resulting gel bands.

01:57Sanger Sequencing
DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...
