We performed a genome-wide association study for semen quality traits in 139 German Warmblood stallions. Stallions were genotyped using the Illumina equine SNP50 Beadchip. Traits analysed were de-regressed estimated breeding values (EBVs) for gel-free volume, sperm concentration, total number of sperm, progressive motility and the total number of progressively motile sperm. The GWAS revealed 29 SNPs on 12 different chromosomes as genome-wide significantly associated with semen quality traits. For ten genomic regions we could retrieve candidate genes influencing stallion fertility. Among the candidate genes, we could find the genes encoding cysteine-rich secretory proteins (CRISP1, CRISP2 and CRISP3). This was the first GWAS in horses performed for semen quality traits.
我们对139匹德国温血种公马的精液质量性状进行了全基因组关联研究。使用Illumina马SNP50芯片对种公马进行基因分型。分析的性状为去回归估计育种值(EBV),包括无凝胶体积、精子浓度、精子总数、前向运动性以及前向运动精子总数。全基因组关联研究揭示了12条不同染色体上的29个单核苷酸多态性(SNP)与精液质量性状在全基因组水平上显著相关。对于10个基因组区域,我们能够检索到影响种公马生育力的候选基因。在候选基因中,我们发现了编码富含半胱氨酸分泌蛋白的基因(CRISP1、CRISP2和CRISP3)。这是首次针对精液质量性状在马匹中进行的全基因组关联研究。
