  1. Rlean meat percentage is one of the most important economic traints in pig breeding programs. myostatin is a negative regulator of skeletal muscle growth. null or low activity of myostatin, individual muscle of mutant amimals would show a large and widespread increase in skeletal mass. myostatin null animals have significantly larger diameter or more quantity of fiber skeletal muscle. the phenotype was termed double muscling. in order to probe the relation between myostatin and high lean meat rate and plump - hipped trait, we sythesized the c ' 80 amino acids coding sequence of porcine myostatin and costructed the cloning and expressing vector of it
