| Abstract: | In order to determine the role of related candidate genes in the process of hair color making a difference and the relationship between them, the molecular mechanism of Mongolian horse hair color formation in fetal period was analyzed, for laying the foundation for the future protection, development and utilization of Mongolian horse(spotted). In this study, Mongolian horse(spotted)fetuses were taken as the research object. Firstly, paraffin sections of skin tissue in white and black areas of Mongolian horse body during fetal period were made and histological observations were carried out. Secondly, RNA-seq was performed on the white and black skin of fetal Mongolian horses to construct mRNA expression profile, screen-related differentially expressed genes, and perform GO and KEGG functional enrichment analysis. The results showed that 1)Through histological observation, melanin deposition was obvious in the epidermis of fetal black skin tissue, and melanin deposition was found in the nipple and hair matrix. Instead, there was no melanin deposition in white skin tissue. 2)RNA-seq was used to screen the related genes related to the difference in hair color. A total of 660 genes were identified, and there were significant differences in the expression of black and white skin tissues(P<0. 05). Among them, 197 genes were highly expressed in black skin tissues of Mongolian horse fetus, and 59 genes were highly expressed in white skin tissues of Mongolian horse fetus. The differentially expressed genes such as TYR, TYRP1, DCT, PAX3 and DAPL1 were enriched in melanin production pathway. In summary, the hair color formation of Mongolian horse during fetal period is mainly determined by genes related to melanin formation. It provides a scientific theoretical basis for the selection of hair color in the breeding of Mongolian spotted horses. |
