Abstract

Body measurement traits (BMTs), which are classical quantitative traits of vital responses to body growth, have been studied in pigs, cattle, and sheep for several decades. In chickens, BMTs mainly cover body slope length, keel length, chest width, chest depth, tibia length, and tibia diameter; however, their genetic markers are yet to be considered. In this study, the Wenshang Barred chicken, a meat-egg-type native breed in China, was used to investigate the association between BMTs and the expression of growth-related genes, including GH, IGF1, IGF2, GHRL, IGF1R, IGFBP2, GHF-1, and TSHB. The results revealed that the single nucleotide polymorphism (SNP) rs3138025 in GH was significantly associated with keel length (P=0.0455 <0.05), rs313810945 in IGF2 was significantly correlated with chest width (P=0.0454 <0.05) and chest depth (P=0.0259 <0.05), and rs317298536 in TSHB significantly affected chest depth (P=0.0399 <0.05). The SNPs were associated with traits reflecting body size and were potentially involved in bone growth, which was consistent with studies in humans, rodents, and other vertebrate species. In addition, a borderline significant association was found between rs317298536 and body weight (P=0.0604). These polymorphic sites may be treated as candidate genetic markers in breeding programs involving Wenshang Barred chickens.

生长相关基因对文上条鸡体测量性状的影响。
身体测量性状(BMTs)是对身体生长的重要反应的经典数量性状,已经在猪、牛和羊身上进行了几十年的研究。鸡主要包括体坡长、龙骨长、胸宽、胸深、胫骨长、胫骨直径;然而,他们的遗传标记还没有被考虑。本研究以中国肉蛋型地方品种文上杠鸡为研究对象,研究了BMTs与生长相关基因(GH、IGF1、IGF2、GHRL、IGF1R、IGFBP2、GHF-1和TSHB)表达的关系。结果显示,GH中单核苷酸多态性(SNP) rs3138025与龙骨长度显著相关(P=0.0455), IGF2与胸宽显著相关(P=0.0454 P=0.0259), TSHB显著影响胸深(P=0.0399 P=0.0604)。这些多态性位点可作为汶上白斑鸡育种计划的候选遗传标记。
