摘要
公猪精液品质直接影响到猪场经济效益,通过转录组测序发现SPATA6基因在猪性成熟前后的睾丸组织中差异表达,并发现其内含子区域内存在多个SNP位点。通过SNaPshot的方法分别对杜洛克猪和大白猪中SPATA6基因的rs331255092和rs341061477位点进行分型,并与精液品质性状进行关联分析。结果表明,在杜洛克猪和大白猪中rs331255092和rs341061477位点均与精子畸形率显著相关,此外,在大白猪中rs331255092和rs341061477位点也与精液量显著相关。猪SPATA6基因的rs331255092和rs341061477位点对猪的精液品质存在潜在调控作用。
The quality of boar semen directly affects the economic benefits of pig farms. Transcriptome sequencing showed that SPATA6 gene was differentially expressed in testicular tissues of porcine sexually mature and immature, and multiple SNP sites were found in its intron region. In this study, rs331255092 and rs341061477 loci of SPATA6 gene were identified by SNaPshot method in Duroc pig and Large White pig. The results showed that rs331255092 and rs341061477 were significantly correlated with sperm abnormality rate in Duroc pig and Large White pig. In addition, rs331255092 and rs341061477 were also significantly correlated with semen volume in Large White pig. In summary, rs331255092 and rs341061477 have potential regulatory effects on semen quality in pigs.
