The origin and domestication history of domestic horses and the domestication characteristics of breeds. The horse (Equus caballus) was domesticated thousands of years after dog, cattle, pig, sheep, and goat. Importantly, it represents the domestic animal that mostly impacted the development of human civilization. Its excellent loading and moving ability prompted the changes from fixed farming mode into mobile sharing mode. Accordingly, its domestication history deserves considerable attention. So far, many issues have long been controversial, due to the extinction of the closest wild relatives and the dramatic reduction of genetic diversity. With the continuous development of sequencing technolo...
[A multiplex PCR method based on nuclear and cytoplasmic inheritance to identify the horse and donkey-derived components of Asini Colla Corii and the hide]. To identify the original components of Asini Colla Corii and its raw material hides provides a guarantee for authenticity of Asini Colla Corii. It is urgent for Asini Colla Corii production enterprises and market supervision departments to develop effective identification methods of Asini Colla Corii and hides derived from horses, donkeys, mules and hinnies. This study screened species-specific DNA sequences of nuclear and mitochondrial genomes as detection targets, designed horse and donkey specific primers and established multiple PCR identification methods for identifying the animal hides (...
[Overview of the genetic control of horse coat color patterns]. Mammalian coat color is one of the first phenotypic changes resulting from positive selection by humans, and it serves important roles in genetic and evolutionary processes. Among them, horses show a broad variety of coat color patterns, based on which it is difficult to distinguish the real phenotypes, resulting in confused records in horse breed registration. Thus, research in the genetic mechanisms on the development of coat color patterns is significant in horse reproduction and breeding. With the recent establishment of genomics and sequencing technologies, there are significant advances ...
[Effects of Kit gene on coat depigmentation in white horses]. Coat color of horse is an important basis for both species identification and individual recognition and is also one of the important references traits for breeding. Therefore, the research on the mechanism of coat fading has become an important part of horses' coat color study. It has been found that the white phenotype is closely related to the mutation of kit gene, which is located on chromosome 3. Investigated results showed that the formation of the epidermal melanoblast and melanin relies on the expression of kit gene, which determines the presence of white phenotype. Nevertheless, studi...
[Molecular basis and applicability in equine color genetics]. Coat color can be used not only in identifying individuals and species, but also in diagnosing certain diseases. The coat color of horse mainly depends on the distribution and proportion of eumelanin and phaeomelanin, generated by melanocytes, which are regulated by the genes such as MC1R, ASIP, KIT, TYRP, and EDNRB. In addition, STX17, MATP, and PMEL17 also play a role in the formation of coat color of horse. In this review, the action mechanism of candidate genes for coat color and association of DNA sequence polymorphism of these candidate genes with color pattern phenotypes and melanoma we...
[Progress on horse genome project]. There is unique genetic information belonging to various kinds of living beings. Understanding of the formation process of organisms and a variety of vital movement is associated with the achievements of genome study. As horse has a notable health condition and great record of the genealogy in the world, thus it becomes a valuable model animal for studying life science. Despite of a late start, the map of the horse genome has undergone unprecedented expansion during the last few years. The current progresses of the horse genome, including genetic map, physical map, comparative genomic map, and...
[Applications of SSCP and HMA for polymorphic analysis of horse MHC-I alleles]. In this article, we report the analysis of genetic polymorphisms of horse MHC-I molecules by SSCP and HMA, which are methods based on the technique of polyacrylamide gel electrophoresis (PAGE). Our results showed that SSCP was not a suitable method for the analysis of genetic polymorphisms of horse MHC-I molecules due to the failure in generating satisfied separation of DNA fragments, even if experimental conditions were optimized. However, the HMA method produced clearly separated DNA fragments of horse MHC-I molecules, after the experimental conditions, such as the running temperature and th...
[Progress in the study of genetic diversity of Mongolian horse]. Mongolian horse is a kind of important breed resource of local horses in our country. It has a lot of advantages such as powerful endurance, rough feeding resistance, and strong disease resistance. These advantages have become driving force for in-depth study on Mongolian horse. Genetic diversity can reflect all the genetic information of a species or a variety, namely, it reflects the richness of genetic diversity and confirms the degree of uniqueness of genetic resources through genetic markers. This paper introduces the progress in the study on genetic diversity of Mongolian horse in many a...
[PCR-RFLP analysis of the mtDNA Cytb gene in three different horse breeds]. Restriction endonucleases, namely BamH I, Taq I, Hae III, Rsa I and Hinc II, were used to analyze the polymorphism of partial mtDNA Cytb gene sequences from 256 horses 6 types (Thoroughbred, Sanhe, Wuzhumuqin, Xinihe, Wushen and Pony) including the imported breed, cultivated breed and local breed. The products of endonuclease digestion were run on 8% non-denaturing polyacrylamide gel electrophoresis and detected by silver staining. Results indicated BamH I and Taq I polymorphism. In all 7 restriction patterns were defected that could be sorted into 3 haplotypes, of which haplotypes I and III w...
[Sequence comparing of mtDNA D-Loop varied region in Chinese Mongolian horse and External Thoroughbred horse]. Mitochondrial DNA D-Loop varied region 400 bp sequence variations in 4 Chinese Mongolian horses and 4 External Thoroughbred horses were analyzed in this experiment. The results showed that the average nucleotide mutational rate of mtDNA D-Loop varied region in 4 Chinese Mongolian horses was 3.69%, while External Thoroughbred horses were 4.00%. Three types of mutations including transition, transversion and deletion were all found in the investigated mtDNA D-Loop regions, of which transition was the most frequent. Nucleotide mutational loci were abundant, length mutations were found and great d...
