Summary
New sequencing technologies offer faster and more accurate gene mapping. These advanced methods enable precise mutation identification, even in non-model species without genome references.
Area of Science:
- Genetics
- Genomics
- Molecular Biology
Context:
- Traditional gene mapping relies on constructing genetic linkage maps, a process that is often laborious, time-consuming, and yields low accuracy with large mapping intervals.
- The advent of high-throughput sequencing and reduced sequencing costs has revolutionized gene mapping approaches.
Purpose:
- To review and summarize novel sequencing-based gene mapping technologies.
- To highlight the advantages of these new methods over traditional techniques.
Summary:
- Discusses various sequencing-based gene mapping strategies, including direct mutant genome sequencing, pooled DNA sequencing, population sequencing for genetic map construction, and transcriptome/partial genome sequencing.
- Emphasizes the ability of these methods to identify nucleotide-level mutations and their applicability in complex genetic backgrounds.
- Highlights recent advancements enabling gene mapping without reference genomes, hybridization, or genetic linkage data, expanding possibilities for non-model organisms.
Impact:
- Enables rapid and accurate gene mapping, accelerating genetic research.
- Facilitates forward genetic studies in a wider range of species, including non-model organisms.
- Provides a comprehensive overview of cutting-edge gene mapping technologies for researchers.

Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...

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.

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...

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...
