Breast muscle RNA-seq data of three pigeon breeds

The purpose of this study was to explore the differences in myofiber characteristics and molecular regulation mechanism among different pigeon breeds.In this study, breast muscle of 23-day-old Silver king pigeon, Sheek-kee pigeon and European meat pigeon Mimas strain squabs were taken as research objects. The phenotypic differences of pectoralis myofibers were observed by HE staining, and genes that may affect the pectoral muscle development of different pigeon breeds were screened by transcriptome sequencing, and verified by real-time fluorescent quantitative qPCR.The results obtained in this study showed that there were significant differences in myofiber characteristics among different breeds and gender of pigeon squabs, and the differential expression of myogenesis and adipogenesis related genes among different breeds and genders would provide data basis for molecular marker-assisted breeding of growth performance of meat pigeons in the future.
