Efficiency of circulant diallels via mixed models in the selection of papaya genotypes resistant to foliar fungal diseases
Authors: M. Vivas, S.F. Silveira, A.P. Viana, A.T. Amaral Jr., D.L. Cardoso and M.G. Pereira
Diallel crossing methods provide information regarding the performance of genitors between themselves and their hybrid combinations. However, with a large number of parents, the number of hybrid combinations that can be obtained and evaluated become limited. One option regarding the number of parents involved is the adoption o..

Cytochrome c oxidase subunit I barcoding of the green bee-eater (Merops orientalis)
Authors: I.A. Arif, H.A. Khan, M. Shobrak and J. Williams
DNA barcoding using mitochondrial cytochrome c oxidase subunit I (COI) is regarded as a standard method for species identification. Recent reports have also shown extended applications of COI gene analysis in phylogeny and molecular diversity studies. The bee-eaters are a group of near passerine birds in the family Meropidae. ..

Development of the first polymorphic microsatellite markers for the Roman snail Helix pomatia L., 1758 (Helicidae) and cross-species amplification within the genus Helix
Authors: A.M. Krapal, O.P. Popa, E.I. Iorgu, L.B. Cojocaru, A.F. Popa and L.O. Popa
The terrestrial snail Helix pomatia (Gastropoda: Stylommatophora: Helicidae) is one of the largest gastropod species in Europe. This species is strictly protected in some European Union countries; however, at the same time, it is also farmed and commercialized for human consumption. Here, we describe 11 microsatellite markers that are very useful in popul.. Read More»

Evolutive and structural characterization of Nostoc commune iron-superoxide dismutase that is fit for modification
Authors: Y. Ma M. Lu J.-Y. Li Y. Qin X.-G. Gong
Superoxide dismutase (SOD) has extensive clinical applications for protecting organisms from toxic oxidation. In this study, the integrated iron-superoxide dismutase gene (fe-sod) coding sequence of Nostoc commune stain CHEN was cloned from genomic DNA and compared to sods from other reported algae. These analyses of immunology and phylogenetics indicated th.. Read More»

New microsatellite loci for the mandarin fish Siniperca chuatsi and their application in population genetic analysis
Authors: C.X. Tian, X.-F. Liang, M. Yang, Y.Q. Dou, H.Z. Zheng, L. Cao,Y.C. Yuan and C. Zhao
The mandarin fish is a popular fresh water food fish in China. Fifty-three polymorphic microsatellite markers were isolated through construction of an enriched library of genomic DNA of Siniperca chuatsi (Percichthyidae). We found 2 to 7 alleles per locus. The observed and expected heterozygosity values varied from 0.059 to 1... Read More»

Intravarietal polymorphisms reveal possible common ancestor of native Schinus terebinthifolius Raddi populations in Brazil
Authors: J.V.C. Pinto1, B.A. Crispim2, A.A. Vasconcelos3, D. Geelen4, A.B. Grisolia2 and M.C. Vieira1
Schinus terebinthifolius Raddi is a perennial native from Atlantic forest. It is of high ecological plasticity and is used in traditional medicine. Based on promising reports concerning its bioactivity, it was included as a species of great interest for distribution through the National Health System. A number of agronomic studies to guide its crop produc.. Read More»

New cytogenetic aberrations found in a case of aggressive retinoblastoma
Authors: J.E.X.S. Barros, E.M. Soares-Ventura, N. Santos, B.A.S. Amaral, F.M. Oliveira, R.S. Vera Cruz, V.L.L. Morais, T.J. Marques-Salles and M.T.C. Muniz
We describe a case of retinoblastoma with an atypical presentation and previously unreported cytogenetic aberrations. A 19-month-old girl with left intraocular retinoblastoma was treated with enucleation and chemotherapy. The disease showed aggressive evolution within a short period between diagnosis and relapse. Eight months .. Read More»

Genetic evidence for panmixia of Japanese eel (Anguilla japonica) populations in China
Authors: X.L. Gong, S.J. Ren, Z.K. Cui and L.J. Yue
The Japanese eel population has dramatically declined since the 1970s. In order to conserve this species, the background genetic structure affecting these populations should be well documented. Previous genetic studies of this species have produced seemingly conflicting results, ranging from no detectable heterogeneity to smal.. Read More»

Imprinted gene expression in in vivo- and in vitro-produced bovine embryos and chorio-allantoic membranes
Authors: F. Perecin S.C. M�©o W. Yamazaki C.R. Ferreira G.K.F. Merighe F.V. Meirelles J.M. Garcia
Cloning by nuclear transfer is often associated with poor results due to abnormal nuclear reprogramming of somatic donor cells and altered gene expression patterns. We investigated the expression patterns of imprinted genes IGF2 and IGF2R in 33- to 36-day bovine embryos and chorio-allantoic membranes derived from in vivo- and .. Read More»

Differential expression of the MHM region and of sex-determining-related genes during gonadal development in chicken embryos

The chicken (Gallus gallus) embryo has been used as a classic model system for developmental studies because of its easy accessibility for surgical manipulation during embryonic development. Sex determination in birds is chromosomally based (ZZ for males and ZW for females); however, the basic mechanism of sex determination is.. Read More»
