Abstract:

In order to study and clarify the expression changes of genes related to polyamine metabolism and muscle development in ducks’ muscle tissue,high performance liquid chromatography and RT-qPCR method were used to detect the polyamine contents and the expressions of polyamine metabolism and muscle development-related genes in the breast and leg muscle tissues during duck postnatal stage on day 0 to 120,and then to analyze the correlation between the expressions of muscle development-related gene and polyamine metabolism. Results showed that the contents of putrescine,spermidine and spermine in the duck breast and leg muscle at 0 days were the highest,and the polyamine metabolism genes in the breast and leg muscle tissue showed regular changes,respectively. In pectoral muscle tissue,the expressions of MyoD1 and Myf5 were the highest in 0 days,MyoG and IGF-1 were the highest at 30 days,and MSTN had the highest expression at 90 days,and MyoD1 and Myf5 genes were significantly and positively correlated with SPMS,SPDS,SSAT,and SMO genes. In leg muscle,ODC was significantly and positively correlated with MyoD1 and MSTN gene. The above results suggest that the changes in polyamine content,polyamine metabolism and muscle development-related gene expression in duck muscle tissues present a certain similarity,so as to provide the reference for studying polyamine regulating duck muscle development action mechanisms.
