摘要 以籽鹅为实验材料,根据鸡生长激素受体(GHR)基因mRNA序列设计并合成引物,通过PCR技术克隆了鹅GHR基因,并利用TaqMan实时荧光定量PCR方法检测籽鹅出壳到90日龄GHRmRNA在部分组织中的表达量变化。结果表明:鹅与鸡和鸭的GHR基因核苷酸序列同源性为97.1%和99.1%,氨基酸同源性均为99.1%。籽鹅肝组织中GHRmRNA表达水平在10到90日龄都较高,显著高于1日龄,以30日龄的表达量最高。30日龄GHRmRNA在肝脏等检测的组织中都有表达,但在肝脏和骨骼肌中的表达量高。肝组织中GHRmRNA表达量与日增重呈显著正相关(r=0.9116)。本实验结果揭示了生长期籽鹅组织中GHRmRNA表达水平的差异,为进一步研究生长轴相关基因对鹅生长及繁殖的调控作用奠定基础。
