Abstract:

Skeletal muscle development is a complex process involving the formation and proliferation of muscle cells,the formation of muscle ducts and muscle fibers,and the final maturation process.The growth and development of skeletal muscle directly affects the production performance in sheep.With the development of sequencing technology,more and more people are trying to elucidate the systematic regulatory network of skeletal muscle development from the genetic level,and explore the molecular markers related to the important functional traits such as meat quality and meat production performance.Cell enhancement factor 2 (MEF2) is a conserved and functional transcription factor that controls the expression of muscle genes and plays a role in regulating muscle generation,neural development and differentiation.Myogenic differentiation (MyoD) gene family regulates the differentiation of myocytes and the maturation of skeletal muscle system.In order to further understand the function of sheep skeletal muscle and its growth and development regulatory genes,starting from the structural features of skeletal muscle,this paper focuses on the structure and function of MEF2 and MyoD genes family and the regulation of non-coding gene on gene expression in skeletal muscle.

Key words: sheep; skeletal muscle; MEF2 gene; MyoD gene; growth and development
