摘要 骨形态发生蛋白2 (bone morphogenetic protein 2, BMP2)能够起始、促进和维持骨的再生。BMP2在促进脂肪形成也有着重要作用,与绵羊(Ovis aries)尾型的形成相关。本实验选择BMP2做候选基因,寻找与尾性状相关的位点和可用的分子标记。在533只绵羊实验群体中,选取藏羊、湖羊两个品种各30个个体的血液样本,等量混合分别构建两个DNA混池,对BMP2基因的外显子及其上、下游1 000 bp进行扩增,针对筛选到的突变位点进行飞行质谱基因分型,利用Haploview4.1软件进一步进行连锁不平衡分析,使用SPSS19.0软件将突变位点与尾型关联分析。结果显示,在BMP2基因及其上下游1 000 bp,共找到7个突变位点,其中rs402970343、rs594116558、rs160577302和rs429072090位点与尾长、尾宽以及尾周长相关,rs417201901和rs402226298位点与尾宽和尾周长相关,rs413373794位点的3种基因型仅在尾宽上存在差异。连锁不平衡分析结果表明,rs417201901-rs402970343,rs413373794-rs402226298-rs429072090之间存在强连锁,组合基因型与尾型关联分析结果显示,CCGG型和CCCCGG个体的尾长、尾宽和尾周长平均值与其他基因型相比均表现出优势,达到显著(P<0.05)或者极显著(P<0.01)水平。BMP2基因对绵羊的尾型有着较为显著的影响,其SNP位点作为分子标记对于绵羊尾型选育工作有着一定的指导意义。

Abstract:Bone morphogenetic protein 2 (BMP2) is named for its ability to initiate, promote and maintain the regeneration of cartilage and bone. In recent years, studies have found that BMP2 played an important role in promoting fat formation and was associated with the formation of sheep (Ovis aries) tail type. Therefore, BMP2 was chosen to be a novel candidate gene for the sheep tail traits in order to find new molecular markers for breeding. In the 533 sheep experiment group, 30 DNA samples of Hu sheep or Tibetan sheep with a fixed concentration were selected to construct the DNA pool, respectively, primers were designed to extend exons and 1 000 bp of upstream and downstream regulation regions. PCR products were tested and the objective strap-was sequenced. Sequenom Mass-array technology was used for genotype of detecting SNP. Haploview 4.1 was used to construct haplotypes and analyze linkage disequilibrium of the polymorphic loci. Association analysis between the SNPs in BMP2 gene and the tail traits were performed using SPSS 19.0 software. 7 SNPs were detected. rs402970343, rs594116558, rs160577302 and rs429072090 were related to tail length, tail width and tail perimeter. rs417201901 and rs402226298 were involved in tail width and tail perimeter. rs413373794 was only related to tail width. Meanwhile, the combined genotype of rs417201901-rs402970343 and rs413373794-rs402226298-rs429072090 correlation analysis revealed that: Individuals with CCGG and CCCCGG combined genotypes were significantly better than the other individuals on tail length, tail width and tail perimeter (P<0.05 or P<0.01). The results showed that the different SNPs and combined genotypes in BMP2 gene had effect on sheep tail traits with the SNPs being potentially valuable as genetic markers for breeding.
