Abstract: The aim of this study was to obtain Chinese Merino sheep full-length sequence of the coding region (CDS) of fibroblast growth factor 10 (FGF10) gene,to analyze its sequence characteristics by bioinformatics method,and to study the expression characteristics of FGF10 gene.It could lay a theoretical foundation for further study of the expression and regulation mechanism of FGF10 mRNA in Chinese Merino hair follicle.The full CDS of FGF10 gene was obtained by PCR amplification and cloned into zero PCR@TM-Blunt for sequencing verification.Real-time quantitative PCR (qRT-PCR) was used to detect the expression pattern of FGF10 gene.The results showed that the sheep FGF10 CDS was 696 bp in length (Upload the sequence to GenBank and get the accession No.:MT872422),which coded 231 amino acids,the homology of amino acid sequence with cattle and goat was 100%,there was a signal peptide and a transmembrane domain,which was the signal protein of secretory pathway.qRT-PCR analysis showed that FGF10 gene was expressed during the development of Chinese Merino follicles,and the highest expression was found on the 85th day of hair follicle development,which was significantly higher than those of other hair follicle development stages.The complete CDS and expression characteristics of FGF10 gene were obtained.Bioinformatics analysis showed that the CDS of FGF10 gene was conserved among species,and the gene was expressed in the skin tissue of different development periods of hair follicle,which indicated that FGF10 gene might play an important role in the growth and development of sheep hair follicles physical function.
