摘要
大理石纹是最重要的牛肉品质特征之一。最近发表的一项研究表明，位于 EGFLAM（EGF 样纤维粘连蛋白和层粘连蛋白 G）的一个非同义变异与汉和牛的大理石纹之间存在关联。因此，我们研究了该 SNP（rs109436056 SNP）与利木赞牛大理石纹之间的关系。共对 355 头牛进行了大理石纹表型和该 SNP 的基因分型。与大理石纹显著相关（p
Association of an EGFLAM non-synonymous polymorphism with marbling in Limousin cattle
Marbling is one of the most important beef quality traits. An association between a non-synonymous variant located in EGFLAM (EGF-like fibronectin and laminin G) and marbling in Hanwoo cattle has recently been published. We therefore investigated the association between this SNP (rs109436056 SNP) and marbling in Limousin cattle. A total of 355 animals were phenotyped for marbling and genotyped for this SNP. Significant association (p < 0.05) was observed, in which genotype CC exhibited higher marbling. This SNP could be used for the genetic improvement of marbling in Limousin cattle.
期刊介绍：
Animal Genetics reports frontline research on immunogenetics, molecular genetics and functional genomics of economically important and domesticated animals. Publications include the study of variability at gene and protein levels, mapping of genes, traits and QTLs, associations between genes and traits, genetic diversity, and characterization of gene or protein expression and control related to phenotypic or genetic variation.
The journal publishes full-length articles, short communications and brief notes, as well as commissioned and submitted mini-reviews on issues of interest to Animal Genetics readers.
