Chromosomal distribution of two multigene families and the unusual occurrence of an X1X1X2X2/X1X2Y sex chromosome system in the dolphinfish (Coryphaenidae): An evolutionary perspective
Authors: R.X. Soares, L.A.C. Bertollo, M.B. Cioffi, G.W.W.F. Costa and W. F. Molina
olphinfishes (Coryphaenidae) are pelagic predators distributed throughout all tropical and subtropical oceans and are very important for commercial, traditional, and sport fishing. This small family contains the Coryphaena hippurus and Coryphaena equiselis species whose chromosomal aspects remain unknown, despite recent advanc.. Read More»

Authors: J.S.B. Ferreira, S.R. Paiva, E.C. Silva, C.M. McManus, A.R. Caetano, D.A.E. Fa�§anha and M.A.N. de Sousa
The aim of this study was to analyze genetic diversity and population structure among varieties of White (N = 40), Red (N = 32), and Black (N = 31) Morada Nova hair sheep from flocks in the northeastern Brazilian semiarid region. Fifteen nuclear microsatellite markers and two regions of mitochondrial DNA were used. The intra-p.. Read More»

Expression of immune response genes in peripheral blood of cattle infested with Rhipicephalus microplus
Authors: R. Domingues, S. Wohlres-Viana, D.R.L. Reis, H.C. Teixeira, A.P. Ferreira, S.E.F. Guimar�£es, M.C.A. Prata, J. Furlong, R.S. Verneque and M.A. Machado
The bovine tick Rhipicephalus microplus is responsible for severe economic losses in tropical cattle production. Bos indicus breeds are more resistant to tick infestations than are Bos taurus breeds, and the understanding of the physiological mechanisms involved in this difference is important for the development of new method..

Rabbit MSTN gene polymorphisms and genetic effect analysis
Authors: X.B. Qiao, K.Y. Xu, B. Li, X. Luan, T. Xia and X.Z. Fan
We analyzed meat samples of nine pure lines of rabbit and its 37 hybrid combinations by sequencing and single-strand conformation polymorphism techniques to explore genetic polymorphisms of all the three exon regions and part of the 5'-regulatory region of the myostatin (MSTN) gene. Thus, we detected a single nucleotide mutati.. Read More»

Insulin-like growth factor I gene polymorphism associated with growth and carcass traits in Thai synthetic chickens
Authors: N. Promwatee, B. Laopaiboon, T. Vongpralub, Y. Phasuk,S. Kunhareang, W. Boonkum and M. Duangjinda
Four Thai synthetic chicken lines (Kaen Thong, Khai Mook Esarn, Soi Nin, and Soi Pet) originated from Thai native and exotic commercial chickens were evaluated for their growth and carcass traits with the purpose of developing a Thai broiler breeding program. Insulin-like growth factor I (IGF-I) gene is known to play an important role in growth, prolifera.. Read More»

Comparison of bivariate and multivariate joint analyses on the selection loss of beef cattle
Authors: V.B. Pedrosa, E. Groeneveld, J.P. Eler and J.B.S. Ferraz
For genetic evaluation of beef cattle, univariate or bivariate analyses are often performed as an alternative to decrease the complexity of matrices and mathematical models compared to multivariate analysis, which considers a larger number of joint traits. The use of bivariate methods to calculate genetic predictors may cause .. Read More»

Construction and functional study of pGN, a mammary gland-specific expression plasmid
Authors: J. Lin, Q.H. Yu, Q. Zhang and Q. Yang
The aim of this study was to construct a mammary gland-specific expression vector, pGN, and to validate its function in expressing growth hormone (GH) both in vitro and in vivo. First, the GH gene was amplified and inserted downstream of the b-casein 5'-arm. Next, the neo gene was cloned downstream of the b-casein 3'-arm as a .. Read More»

Molecular cloning and characterization of KISS1 promoter and effect of KISS1 gene mutations on litter size in the goat
Authors: X.P. An, P. Han, J.X. Hou, H.B. Zhao, Y. Yan, T. Ma, F. Fang, F.X. Meng, Y.X. Song, J.G. Wang and B.Y. Cao
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 met.. Read More»

Quantitative genetic study of age at subsequent rebreeding in Nellore cattle by using survival analysis
Authors: M.H. Van Melis, L.G.G. Figueiredo, H.N. Oliveira, J.P. Eler,G.J.M. Rosa, M.L. Santana Jr., F.M. Rezende and J.B.S. Ferraz
The continuous trait age at subsequent rebreeding (ASR) was evaluated using survival analysis in Nellore breed cows that conceived for the first time at approximately 14 months of age. This methodology was chosen because the restricted breeding season produces censored data. The dataset contained 2885 records of ASR (in days)... Read More»

Authors: J.B. Gao, Y.K. Li, N. Yang, X.H. Ma, C. Adoligbe, B.J. Jiang, C.Z. Fu,G. Cheng and L.S. Zan
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 5êÂ?Â?-untranslated region, 1532C.. Read More»
