摘要: 本研究旨在探讨肌肉生成抑制素(myostatin,MSTN)和肌细胞生成素(myogenin,MyoG)基因对鹅骨骼肌生长发育的影响。试验以莱茵鹅和籽鹅为研究对象,采用实时荧光定量PCR方法测定MSTNMyoG基因在籽鹅和莱茵鹅胸肌、腿肌中的差异表达情况,运用统计软件对基因表达情况与屠宰性状间的相关性进行分析。结果显示,莱茵鹅胸肌重和胸肌率极显著高于籽鹅(P<0.01),籽鹅胸肌MSTN、MyoG mRNA表达量极显著高于莱茵鹅(P<0.01);在腿肌中,籽鹅MSTN mRNA表达量极显著低于莱茵鹅(P<0.01),籽鹅与莱茵鹅MyoG mRNA表达量间无显著差异(P>0.05)。同一品种MSTN mRNA表达水平也存在差异,在籽鹅胸肌和腿肌中表达量存在极显著差异(P<0.01);在莱茵鹅胸肌和腿肌中表达量存在显著差异(P<0.05)。就MyoG mRNA而言,在籽鹅和莱茵鹅胸肌和腿肌中表达量存在极显著差异(P<0.01)。MSTN基因表达与屠宰性能相关性分析表明,胸肌中MSTN mRNA表达量与活重、胸肌重和胸肌率呈极显著负相关(P<0.01);胸肌和腿肌中MyoG mRNA表达量与活重呈极显著正相关(P<0.01)。说明MSTNMyoG基因可能对肌肉生长分别起正负调控作用。

Abstract: The aim of this study was to investigate the effects of MSTN and MyoG genes on goose skeletal muscle growth.In this study,MSTN and MyoG genes expression were detected in breast and leg muscle of Zi and Rhine goose by Real-time PCR,and the correlations between genes expression levels and carcass traits were investigated.The results showed that the breast muscle weight and breast muscle rate of Rhine goose were extremely significant higher than Zi goose (P<0.01).MSTN and MyoG mRNA expression in breast muscle of Zi goose were significantly higher than that of Rhine goose,and the mRNA level of MSTN in leg muscle of Rhine was extremely significant higher than that of Zi goose (P<0.01),there was no significant difference of MyoG mRNA between Zi goose and Rhine goose (P>0.05).There was extremely significant difference between MSTN mRNA expression in breast muscle and leg muscle of Zi goose (P<0.01).MSTN mRNA expression in leg muscle was significantly higher than that of breast muscle of Rhine goose (P<0.05).There was extremely significant difference between MyoG mRNA expression in breast muscle and leg muscle of Zi goose and Rhine goose (P<0.01).There was a extremely significant negative correlation between MSTN mRNA expression in breast muscle with body weight,breast muscle weight and breast muscle percentage (P<0.01).There was a extremely significant positive correlation between MyoG mRNA expression in breast muscle and leg muscle with body weight (P<0.01).MSTN and MyoG gene might have positive and negative regulation effect on muscle growth.
