Combined genotype; Goat; PCR-RFLP; SNP

Kisspeptins, the product of the KISS1 gene, play an essential role in the regulation of reproductive functions, acting primarily at the hypothalamic level of the gonadotropic axis. We detected polymorphisms of the goat KISS1 gene in 723 individuals from three goat breeds (Xinong Saanen, Guanzhong, and Boer) by DNA pooling, PCR-RFLP, and DNA sequencing methods. We cloned ... more

Goat; Growth traits; Myostatin gene (MSTN); PCR-SSCP; Polymorphism

Mutations in the myostatin (MSTN) gene can inactivate its expression and result in a non-functional protein, which leads to dramatic muscularity and a “double-muscling” phenomenon in many species. Using gene sequencing and polymerase chain reaction-single-strand conformation polymorphism methods, polymorphisms of the MSTN gene were investigated as a candidate marker for ... more

Body measurement traits; DKK4 gene; PCR-SSCP; Qingchuan cattle; SNPs

The aim of this study was to determine whether single nucleotide polymorphisms (SNPs) of bovine Dickkopf homolog 4 (DKK4) are associated with body measurement traits in Qinchuan cattle. By using PCR-SSCP technology and DNA sequencing, we discovered 5 DKK4 SNPs in Qingchuan cattle, including -65G>A and -77G>T in the 5ꞌ-untranslated region, 1532C>G and 1533T>C ... more

ANAPC13; Body measurement traits; Cattle; PCR-SSCP; Polymorphism

Body measurement traits, influenced by genes and environmental factors, play numerous important roles in the value assessment of productivity and economy. There has been some indication that ANAPC13 influences adult height. We used PCR-SSCP and DNA sequencing technology to identify polymorphisms in the ANAPC13 gene. A polymorphism in intron 1 (A > G at base 17) was identified and an ... more

Body measurement traits; Cattle; GDF10 gene; SNP

Body measurement traits are known to play numerous important roles in the assessment of productivity and economic value. They are influenced by several factors, among which genetic factors are predominant. The gene GDF10 is involved in skeletal morphogenesis and is associated with body measurement traits. It may be an important candidate gene for marker-assisted selection. We ... more

Association analysis; Genetic variation; Goat; Production traits; Sine oculis homeobox homolog 6 (Six6) gene

We looked for novel genetic variations within the Six6 gene by PCR-SSCP, DNA sequencing and forced RFLP-PCR and estimated their associations with production traits in 2132 goats of eight indigenous Chinese breeds. A novel single nucleotide polymorphism (NM_001104993.1: g.232T>C) within the goat Six6 gene was identified. The frequencies of allele “C” varied from 0.8621 ... more

Goat; MicroRNA characteristics; Real-time quantitative PCR; Solexa deep-sequencing technology

MicroRNAs (miRNAs) are an important class of small noncoding RNAs that are highly conserved in plants and animals. Many miRNAs are known to mediate a myriad of cell processes, including proliferation and differentiation, via the regulation of some transcription and signaling factors, which are closely related to muscle development and disease. In this study, small RNA cDNA libraries of ... more

DNA extraction; Goat; PCR; semen

Successful DNA extraction is indispensable for molecular methods based on polymerase chain reaction (PCR); however, goat sperm DNA extraction is limited. Thus, the aim of this study was to evaluate three methods to extract DNA from goat sperm for use in PCR. Eight goat semen pools were used for DNA extraction by using the DNeasy Blood & Tissue Kit, phenol-chloroform, and Chelex-100 ... more

Genetic structure; Goat; Microsatellite marker; Phylogeny

The present study aimed to analyze genetic relatedness and differentiation of common native goat populations in some countries of the Middle East. The populations were Ardi, Black Bedouin, and Damascus goats in the Kingdom of Saudi Arabia, Jordan, and Syria, respectively. Domesticated goats of the Middle East are mostly related to common ancestors, but there is limited molecular genetic ... more

Bos taurus; Carcass traits; Chemerin gene; PCR-SSCP; SNP

Qinchuan is a red or yellow draft and beef breed in China. In order to identify a predictor of carcass traits on the basis of associations between carcass traits and gene polymorphism, variation in the bovine chemerin gene was investigated using PCR-single-strand conformational polymorphism and DNA sequencing. An SNP of A868G located in exon 2 of the Bos taurus chemerin gene was ... more
