DNA barcoding and phylogenetic relationships of Ardeidae (Aves: Ciconiiformes)
Authors: Z.H. Huang, M.F. Li and J.W. Qin
The avian family Ardeidae comprises long-legged freshwater and coastal birds. There has been considerable disagreement concerning the intrafamilial relationships of Ardeidae. Mitochondrial cytochrome c oxidase subunit I (COI) was used as a marker for the identification and phylogenetic analysis of avian species. In the present study, we analyzed the COI b.. Read More»

Mapping, expression and regulation of the TRa gene in porcine adipose tissue
Authors: Z.-W. Cai, Y.-F. Sheng, L.-F. Zhang, Y. Wang, X.-L. Jiang, Z.-Z. Lv and N.-Y. Xu
Thyroid hormone receptors (TR) are members of the nuclear receptor superfamily. There are at least two TR isoforms, TRα and TRβ. The TRα isoform plays a critical role in mediating the action of thyroid hormone in adipose tissue. We mapped the porcine TRα gene to chromosome 12 p11-p13, by using the ImpRH .. Read More»

Heritabilities and genetic correlations for reproductive traits in an F2 reciprocal cross chicken population
Authors: R.P. Savegnago, M.E. Buzanskas, B.N. Nunes, S.B. Ramos, M.C. Ledur, K. Nones and D.P. Munari
Studies estimating genetic parameters for reproductive traits in chickens can be useful for understanding and improvement of their genetic architecture. A total of 1276 observations of fertility (FERT), hatchability of fertile eggs (HFE) and hatchability of total eggs (HTE) were used to estimate the genetic and phenotypic para.. Read More»

Damaging effects of water-borne cadmium chloride on DNA of lung cells of immature mice
Authors: X.F. Yang Y.M. Ge H.T. Zhang H.M. Ning J.Q. Jiang Y.H. Qi Z.L. Wang
We investigated the effects of cadmium on lung cell DNA in immature mice. The mice were randomly divided into four groups: control group, low-dose group (1/100 LD50), middle-dose group (1/50 LD50), and high-dose group (1/25 LD50); they were supplied with cadmium chloride or control water for 40 days. Lung cells collected from sacrificed mice were used to .. Read More»

Genetic effect of the prolactin receptor gene on egg production traits in chickens
Authors: L. Zhang D.Y. Li Y.P. Liu Y. Wang X.L. Zhao Q. Zhu
The identification and utilization of potential candidate genes with significant effects on economically important traits have become increasingly important in poultry breeding programs. The prolactin (PRLR) receptor is a specific receptor for prolactin, which is an anterior pituitary peptide hormone involved in various physiological activities and is ess.. Read More»

Mutagenicity of the Musa paradisiaca (Musaceae) fruit peel extract in mouse peripheral blood cells in vivo
Authors: C.U.B. Andrade, F.F. Perazzo and E.L. Maistro
Plants are a source of many biologically active products and nowadays they are of great interest to the pharmaceutical industry. In the present study, the mutagenic potential of the Musa paradisiaca fruit peel extract was assessed by the single-cell gel electrophoresis (SCGE) and micronucleus assays. Animals were treated orall.. Read More»

Karyotypic variability in Iheringichthys labrosus (Teleostei, Pimelodidae) from the Tibagi River basin (Paran�¡ State, Brazil)
Authors: L.B. Ribeiro, D.A. Matoso, M.C. Almeida, M.R. Vicari,A. Moraes-Neto, M.C.C.M. Svidnicki and R.F. Artoni
Cytogenetic analyses were carried out in a populational sample of Iheringichthys labrosus from the Guaraúna River (Upper Tibagi River; Paraná State, Brazil) in order to provide a karyotypic comparison with another previously studied population from the Lower Tibagi River, characterized by the presence of 32m + 8s..

DNA barcode information for the sugar cane moth borer Diatraea saccharalis
Authors: J.P. Bravo, J.L.C. Silva, R.E.F. Munhoz and M.A. Fernandez
We reviewed the use and relevance of barcodes for insect studies and investigated the barcode sequence of Diatraea saccharalis. This sequence has a high level of homology (99%) with the barcode sequence of the Crambidae (Lepidoptera). The sequence data can be used to construct relationships between species, allowing a multidis.. Read More»

Population genetics analysis of Podocnemis sextuberculata (Testudines, Podocnemidae): lack of population structure in the central Amazon Basin
Authors: T.J. Silva, L.A.S. Monjel�³, M.N.S. Viana, J.C. Pezzuti, P.C.M. Andrade, R.C. Vogt and I.P. Farias
The chelonians are, in general, important for the economy of the traditional populations of the Amazon region, especially as a source of animal protein. Furthermore, sub-products, such as eggs and fat, are utilized in the manufacture of cosmetics, and the plastron and carapace are used in the manufacture of adornments. The fre.. Read More»

Evaluation of genetic diversity and population structure in a commercially important freshwater fish Prochilodus costatus (Characiformes, Prochilodontidae) using complex hypervariable repeats
Authors: T.M. Barroca G.B. Santos N.V.R. Duarte E. Kalapothakis
We used complex hypervariable repeats to evaluate the genetic diversity and structure of Prochilodus costatus (Characiformes), an ecologically and economically important species endemic to the São Francisco River basin. Hydroelectric dams along the river have led to population fragmentation, which can limit gene flow. Restocking from hatcheries has.. Read More»
