摘要:

为了探讨血管活性肠肽Ⅰ型受体基因(VIPR-1)的多态性与肉用鹌鹑胴体性状的关系,采用PCR-RFLP方法对法国巨型肉用鹌鹑和莎维麦脱肉用鹌鹑2个群体的VIPR-1基因与肉用鹌鹑胴体性状进行关联分析。结果表明,VIPR-1基因外显子4-5的BsrDⅠ位点在法国巨型肉用鹌鹑和莎维麦脱肉用鹌鹑中检测到3种基因型,即GG、GT、TT基因型,基因型频率分别为:0.408、0.490、0.102;0.222、0.444、0.334。VIPR-1基因外显子6-7的HpyCH4Ⅳ位点在法国巨型肉用鹌鹑和莎维麦脱肉用鹌鹑中检测到AA、AG、GG这3种基因型,基因型频率分别为:0.020、0.020、0.960;0.056、0.111、0.833。关联分析表明,VIPR-1基因外显子4-5的BsrDⅠ位点与法国巨型肉用鹌鹑的肝重有显著关联性(P<0.05);VIPR-1基因外显子6-7的HpyCH4Ⅳ位点与法国巨型肉用鹌鹑的体重、屠宰重、肝重有显著关联性(P<0.05),与莎维麦脱肉用鹌鹑的体重、屠宰重、全净膛重、心重、胸肌重、腿肌重、肝率、胸肌率有显著关联性(P<0.05)。VIPR-1基因可以作为候选基因应用于肉用鹌鹑的分子标记辅助选择。

Abstract:

In order to investigate the relationship between the polymorphism of type 1 vasoactive intestinal peptide receptor (VIPR-1) gene and carcass traits of meat quail, the polymorphism of VIPR-1 gene was detected by PCR-RFLP method in two populations, including French giant meat quail and Savimaito meat quail, and the correlation between the polymorphism of VIPR-1 gene and carcass traits of meat quail was analyzed. The results showed that GG, GT and TT genotypes were detected at the BsrDⅠ locus of exon 4-5 of VIPR-1 gene in French giant meat quail and Savimaito meat quail, the GG, GT and TT genotype frequencies of French giant meat quail and Savimaito meat quail were 0.408, 0.490, 0.102; 0.222, 0.444, 0.334, respectively. AA, AG and GG genotypes were detected at the HpyCH4Ⅳ locus of exon 6-7 of VIPR-1 gene in French giant meat quail and Savimaito meat quail, the AA, AG and GG genotype frequencies of French giant meat quail and Savimaito meat quail were 0.020, 0.020, 0.960; 0.056,0.111,0.833, respectively. The results of association analysis showed that the BsrDⅠ locus in exon 4-5 of VIPR-1 gene was significantly associated with the liver weight of French giant meat quail (P<0.05). The HpyCH4Ⅳ locus in exon 6-7 of VIPR-1 gene was significantly associated with body weight, slaughter weight and liver weight of French giant meat quail (P<0.05), and with the body weight, slaughter weight, eviscerated weight, heart weight, chest muscle weight, leg muscle weight, liver rate and chest muscle rate of Savimaito meat quail (P<0.05). The VIPR-1 gene can be used as a candidate gene for marker-assisted selection of carcass traits in meat quail.
