摘要: The objectives of the present study were to detect an 18-bp deletion mutation in the bovine adenosine monophosphate deaminase 1 (AMPD1) gene and analyze its effect on growth traits in 2 Chinese cattle breeds using DNA sequencing and agarose electrophoresis. The five 19-bp polymerase chain reaction products of the AMPD1 gene exhibited 3 genotypes and 2 alleles: WW: homozygote genotype (wild-type); DD: homozygote genotype (mutant-type); WD: heterozygote genotype. Frequencies of the W allele varied from 66.15-70.35%. The associations between the 18-bp deletion mutation in the AMPD1 gene with production traits in 226 Jia-Xian red cattle was analyzed. The animals with genotype WW showed significantly higher heart girth and body weight than those with genotypes WD and DD at 24 months (P < 0.01). Our results indicate that the deletion mutation in the AMPD1 gene is associated with production traits, and may be used for marker-assisted selection in beef cattle breeding programs.
