A single nucleotide polymorphism in the coding region of bovine transferrin is associated with milk fat yield
Authors: A. Sanz, L. Ordov�¡s, C. Serrano, P. Zaragoza, J. Altarriba and C. Rodellar
The bovine transferrin gene (TF) is located at 125 cM on bovine chromosome 1 (BTA1); it codes for transferrin, a glycoprotein that is highly conserved in many species and that is responsible for iron transport. The TF gene has been located in several QTL regions, and some transferrin classes have been associated with fat and m.. Read More»

Systems genetics and genome-wide association approaches for analysis of feed intake, feed efficiency, and performance in beef cattle
Authors: M.H.A. Santana, M.C. Freua, D.N. Do, R.V. Ventura, H.N. Kadarmideen and J.B.S. Ferraz
Feed intake, feed efficiency, and weight gain are important economic traits of beef cattle in feedlots. In the present study, we investigated the physiological processes underlying such traits from the point of view of systems genetics. Firstly, using data from 1334 Nellore (Bos indicus) cattle and 943,577 single nucleotide po.. Read More»

Expression of �²-defensins in intestines of chickens injected with vitamin D3 and lipopolysaccharide
Authors: L. Lu, S.M. Li, L. Zhang, X.Q. Liu, D.Y. Li, X.L. Zhao and Y.P. Liu
The objective of this study was to evaluate the effect of vitamin D3 (VD3) on the regulation of chicken intestinal b-defensin genes under normal and lipopolysaccharides (LPS) conditions. Four treatment groups were used, including a negative control group, VD3-injection group, LPS-injection group, and both VD3-injection and LPS-injection group. At 4, 24, a.. Read More»

The Caenorhabditis elegans genome: a multifractal analysis
Authors: P.E. VÃ?©lez, L.E. Garreta, E. MartÃ?Ânez, N. DÃ?Âaz, S. Amador, I. Tischer, J.M. GutiÃ?©rrez and P.A. Moreno
The Caenorhabditis elegans genome has several regular and irregular characteristics in its nucleotide composition; these are observed within and between chromosomes. To study these particularities, we carried out a multifractal analysis, which requires a large number of exponents to characterize scaling properties. We looked f.. Read More»

Polymorphic microsatellite loci from two enriched genomic libraries for the genetic analysis of the miiuy croaker, Miichthys miiuy (Sciaenidae)
Authors: R.X. Wang, T.J. Xu, Y.N. Sun and G.Y. He
Twelve polymorphic microsatellites from the (AG)13 and (CA)13 enriched genomic libraries of Miichthys miiuy were isolated and characterized in a test population; the number of alleles ranged from two to nine. The observed and expected heterozygosities ranged from 0.1923 to 1.0000 and from 0.2633 to 0.8337, respectively. Three .. Read More»

Development of a species-diagnostic marker and its application for population genetics studies of the stingless bee Trigona collina in Thailand
Authors: M. Theeraapisakkun, S. Klinbunga and S. Sittipraneed
A molecular maker for authenticating species origin of the stingless bee (Trigona collina) was developed. Initially, amplified fragment length polymorphism analysis was made of 11 stingless bee species using 64 primer combinations. A 316-bp band found only in T. collina was cloned and sequenced. A primer pair (CUTc1-F/R) was d.. Read More»

Comparison of different models to estimate genetic parameters for carcass traits in a commercial broiler line
Authors: J.L.B.M. Grosso, J.C.C. Balieiro, J.P. Eler, J.B.S. Ferraz, E.C. Mattos and T. Michelan Filho
The effect of genetic and non-genetic factors for carcass, breast meat and leg weights, and yields of a commercial broiler line were investigated using the restricted maximum likelihood method, considering four different animal models, including or excluding maternal genetic effect with covariance between direct and maternal g..

Insights about the genetic diversity and population structure of an offshore group of common bottlenose dolphins (Tursiops truncatus) in the Mid-Atlantic
Authors: C.S. Castilho, F. Pedone-Valdez, F. Bertuol, P. Fruet, R.C. Genoves, J.C. Di Tullio, G. Caon, L.S. Hoffmann and T.R.O. Freitas
Although the genus Tursiops has a worldwide distribution and is globally well-studied, some dolphin populations continue to face high risks of decline. Hence, it is necessary to assess the genetic diversity and structure of this genus to properly assess its conservation status and to implement appropriate management actions. In Brazil, genetic studies on .. Read More»

Characterization of microsatellite markers for the Restinga Antwren, Formicivora littoralis (Thamnophilidae), an endangered bird endemic to Brazil
Authors: F.G. Chaves, M.B. Vecchi, M.S. Webster and M.A.S. Alves
Molecular markers are important tools in determining parentage, gene flow, and the genetic structure of species. In the case of rare, endemic, and/or threatened species, these markers can be used to understand key ecological questions and support conservation actions. We developed seven microsatellite markers for the only bird endemic to the Restinga ecos.. Read More»

Authors: J. Liu, L.D. Qian, J.L. Huo, B.L. Bi, D.L. Li, S.F. Wang,T. Chen, L.J. Li, H.M. Mao and Y.W. Miao
Parathyroid hormone-related protein (PTHrP) is involved in the deposition of milk calcium in mammal lactation, but its role in buffalo is unclear. In this study, the full-length coding sequence of the water buffalo PTHrP gene was first isolated using reverse transcription-polymerase chain reaction. The protein was then subjected to molecular characterizat.. Read More»
