Abstract: [Objective] To compare and analyze the transcriptome of pectoral muscle tissues between racing pigeons and ornamental pigeons, and to explore the key genes related to flight performance in pigeon pectoral muscles. [Method] Through differential analysis, the differentially expressed genes that were significantly up-and down-regulated in pectoral muscles between racing pigeons and ornamental pigeons were obtained and enriched. [Result] A total of 18.3 G effective data were obtained by using data quality control. A total of 477 differentially expressed genes, including 194 up-regulated genes and 130 down-regulated genes were screened out. Three candidate genes related to pigeon flight performance were screened out by using KEGG pathway significance enrichment analysis : MUSTN1, PDK4 and MSTN. [Conclusion] By comparing the transcriptome data of the pectoral muscles between racing pigeons and ornamental pigeons, the key genes associated with flight performance of pigeon were obtained. The information provided by this study enriched the genomic information of pigeons and laid the foundation for further elaborating the molecular mechanism of pigeon pectoral muscles.
