DNA barcodes of mitochondrial COI and Cytb genes were constructed from 54 specimens of 16 species for species identification. Intra- and interspecific sequence divergence of the COI gene (10 times) was greater than that of the Cytb gene (4 times), which suggests that the former gene may be a better marker than the latter for species delimitation in snakes..

Genome-wide association study of growth traits in the Jinghai Yellow chicken
Authors: G.X. Zhang, Q.C. Fan, T. Zhang, J.Y. Wang, W.H. Wang, Q. Xue and Y.J. Wang
Growth is one of the most economically important traits in the poultry industry. In this study, we identified single-nucleotide polymorphisms (SNPs) and candidate genes associated with growth traits of the Jinghai Yellow chicken. Genome-wide association studies were conducted using the Illumina 60 K SNP Chicken array to genoty.. Read More»

Egg laying and egg quality in meat type quails in diallel crosses
Authors: E.C.S. Drumond, A.V. Pires, C.M. Bonaf�©, S.R.F. Pinheiro, R.C. Veloso, J.M. Amaral and L.R.A. Abreu
This study aimed to assess egg laying and egg quality in quail lines in diallel crosses. We evaluated 16 genetic groups obtained from crosses of four strains of meat quails (L1, L2, L3, and L4) in a complete diallel. We assessed weekly egg number (WEN), egg yield (EY), egg weight (EW), and Haugh unit (HU) for: 51-80, 81-110, 111-140, and 51-140 days (whol.. Read More»

Genetic and biogeographical relationships among species of Astyanax (Teleostei, Characidae) in Brazilian river basins
Authors: R. Mello, T.C. Maniglia, S.M.A.P. Prioli and A.J. Prioli
The genetic relationships among 17 species of Astyanax from the Iguaçu River and adjacent river basins in Brazil were examined using nucleotide sequences of the mitochondrial cytochrome b gene (cytb). Congruent trees were constructed using neighbor-joining, maximum-likelihood, and Bayesian methods. The.. Read More»

Growth curves of carcass traits obtained by ultrasonography in three lines of Nellore cattle selected for body weight
Authors: C.C. Coutinho1, M.E.Z. Mercadante2, A.M. Jorge1, C.C.P. Paz2, L. El Faro2 and F.M. Monteiro2
The effect of selection for postweaning weight was evaluated within the growth curve parameters for both growth and carcass traits. Records of 2404 Nellore animals from three selection lines were analyzed: two selection lines for high postweaning weight, selection (NeS) and traditional (NeT); and a control line (NeC) in which animals were selected for pos..

Mitochondrial DNA dynamics during in vitro culture and pluripotency induction of a bovine Rho0 cell line
Authors: L.V.F. Pess�´a1, F.F. Bressan1,2, M.R. Chiaratti1,3, P.R.L. Pires1, F. Perecin1,2,L.C. Smith1,4 and F.V. Meirelles1,2
Large number of cellular changes and diseases are related to mutations in the mitochondrial DNA copy number. Cell culture in the presence of ethidium bromide is a known way of depleting mitochondrial DNA and is a useful model for studying such conditions. Interestingly, the morphology of these depleted cells resembles that of pluripotent cells, as they pr.. Read More»

Rapid microsatellite development in Gekko japonicus using sequenced restriction-site associated DNA markers
Authors: L. Wei1, W.W. Shao1, H.B. Zhou2, J. Ping2, L.M. Li3 and Y.P. Zhang2
welve polymorphic microsatellite loci were isolated in the Japanese gecko, Gekko japonicus. We genotyped one population from Wenzhou, Zhejiang Province, China (N = 36). The mean number of observed alleles per locus was 7.3 (range 4 to 13). Observed and expected heterozygosity values ranged from 0.200 to 0.944 and from 0.395 to 0.797, respectively. One loc..

Heritability of predicted daily enteric methane emissions from growing Nellore cattle
Authors: T.L.P. Sobrinho1, M.E.Z. Mercadante2, R.C. Canesin2, J.N.S.G. Cyrillo2,L.G. Albuquerque1 and R.H. Branco2
The objective of this study was to estimate the heritability of predicted daily enteric methane emissions (PME) from growing Nellore cattle. Dry matter intake (DMI) records of 955 Nellore animals that were born between 2004 and 2013, which were obtained in a postweaning performance test lasting 83 ± 15 days, were used. The PME of each animal, obtai.. Read More»

Frequency of gray coat color in native Chinese horse breeds
Authors: K.X. Gao1, N.B. Chen1, W.J. Liu2, R. Li1, X.Y. Lan1, H. Chen1,C.Z. Lei1 and R.H. Dang1
Gray horses are born colored, and they then gradually lose their hair pigmentation. Tremendous progress has been made in identifying the genes responsible for graying with age in horses in recent years. Results show that gray coat color in horses is caused by a 4.6-kb duplication in intron 6 of the syntaxin 17 gene (STX17), which constitutes a cis-acting-.. Read More»

Authors: J.-Q. Wu1, J. Liu1, L.-L. Wang1, A.-G. Xie1 and D.-L. Liu2
The aim of this study was to understand the effect of autologous bone powder graft repair of partial mandibular defects of rabbits by the quantitative detection of bone formation. New Zealand rabbits (N = 18) were selected as the test objects, and subjected to bilateral partial mandibular defect induction. One side of the mandibular defect acted as the te.. Read More»
