Mitochondrial DNA sequencing of Kehilan and Hamdani horses from Saudi Arabia.
Abstract: The Arabian horse breed is well known for its purity and played a key role in the genetic improvement of other horses worldwide. The mitochondrial genome plays a vital role in maternal inheritance and it's helpful to evaluate its genetic diversity and conservation. It has higher mutation rates than nuclear DNA in vertebrates and therefore reveals phylogenetic relationships and haplotypes. In this study, the mitochondrial genome mutations in two Saudi horse strains, Kehilan and Hamdani demonstrated various changes in the gene and amino acid levels and included two other Saudi horses (Hadban and Seglawi) from the previous study for phylogenetic comparison. The whole mitochondrial genome sequencing resulted in intra and inter mtDNA variations between the studied horses. Interestingly, the Hamdani horse has nucleotide substitutions similar to those of the Hadban horse, which is reflected in the phylogenetic tree as a significantly close relationship. This type of study provides a better understanding of mitogenome structure and conservation of livestock species genetic data.

The research article focuses on sequencing the mitochondrial DNA of Arabian horse strains, Kehilan and Hamdani, to evaluate its genetic diversity and conservation.
Objective of the Study
- The main goal of the research was to study mitochondrial genome (mitogenome) mutations in two Arabian horse strains, Kehilan and Hamdani, to evaluate their genetic diversity and conservation.
- The mitochondrial genome is particularly important to understanding maternal inheritance as it possesses higher mutation rates than nuclear DNA in vertebrates, therefore elucidating phylogenetic relationships and haplotypes.
- The study integrates findings from two other Saudi horse strains, Hadban and Seglawi, to provide a phylogenetic comparison.
Findings of the Study
- The whole mitochondrial genome sequencing provided both intra (within species) and inter (between species) mtDNA variations among the Arabian horses studied.
- Significant variations were found at gene and amino acid levels, giving a comprehensive view of the genetic diversity within the studied equine species.
- It was observed that the Hamdani horse strain had nucleotide substitutions similar to those of the Hadban horse, showing an interestingly close phylogenetic relationship.
Significance of the Study
- This research not only provides an in-depth understanding of the mitogenome structures of the studied horse strains but also contributes to the genetic data available for livestock species.
- The findings can be of great importance for conservation practices and in preserving the genetic purity and diversity of Arabian horses.
