畜禽肌肉生成抑制素基因多态性研究进展

Research Progress on the Polymorphism for Myostatin in Livestock

肌肉生成抑制素属于TGFβ超家族成员,该基因功能缺失性突变的个体表现出肌纤维数量和直径显著增大,导致肌肉产量显著增加。总结了MSTN基因在鸡、猪、牛、羊上多态性的研究进展。

Myostatin（MSTN）,a member of transforming growth factor-β（TGF-β） superfamily,the gene loss of function mutations in the individual showed the number and diameter of muscle fibers increased significantly,resulted in a significant increase in muscle production.The polymorphism for MSTN gene in chicken,pig,cattle and sheep was summarized.
