Genetic polymorphisms of loci D18S53, D18S59, and D18S488 in fetuses from a Chinese Tianjin Han population
Authors: X.Z. Li, J. Liu, Y.F. Shi, D. Ju, Y. Zhang and T.F. Yue
We investigated the genetic polymorphisms of three short tandem repeat (STR) loci, D18S53, D18S59, and D18S488, on chromosome 18 in fetuses from a Chinese Tianjin Han population. Sixty-four villus samples and 374 amniotic fluid samples were collected from fetuses. Quantitative fluorescence polymerase chain reaction was perform.. Read More»

A small B chromosome in the grasshopper Ommexecha virens (Ommexechidae)
Authors: T.E. Souza, L.C. Silva-Neto, J.F. Santos, V. Loreto and T.T. Rieger
B chromosomes, also called supernumerary or accessory chromosomes, have been characterized as extra elements found in the karyotypes of different eukaryotic species. B chromosomes are nonvital and only occur in some individuals within a species. Moreover, the chromosomes contain silenced genes, and they exhibit heterochromatinization and the accumulation ..

Physical location of the carotenoid biosynthesis genes Psy and �²-Lcy in Capsicum annuum (Solanaceae) using heterologous probes from Citrus sinensis (Rutaceae)
Authors: V. Andrade-Souza, M.G.C. Costa, C.X. Chen, F.G. Gmitter Jr. and M.A. Costa
Carotenoids are responsible for a range of fruit colors in different hot pepper (Capsicum) varieties, from white to deep red. Color traits are genetically determined by three loci, Y, C1, and C2, which are associated with carotenogenic genes. Although such genes have been localized on genetic maps of Capsicum and anchored in L.. Read More»

Chromosome stickiness impairs meiosis and influences reproductive success in Panicum maximum (Poaceae) hybrid plants
Authors: C. Pessim,M.S. Pagliarini,N. Silva and L. Jank
Chromosome stickiness has been studied in several species of higher plants and is characterized by sticky clumps of chromatin resulting in sterility. Chromosome stickiness was recorded in Panicum maximum hybrid plants that were cultivated in the field. In the meiocytes affected, chromosomes clumped into amorphous masses that did not orient themselves on t.. Read More»

De novo interstitial deletion in the long arm of chromosome 11: a case report
Authors: L.L. Li, H.G. Zhang, X.G. Shao, J.C. Gao, H.Y. Zhang and R.Z. Liu
The 11q terminal deletion disorder is a rare genetic disorder associated with numerous clinical features. A few case reports have been made about de novo interstitial deletion of chromosome 11q. However, due to the heterogeneity in size and position of the deletions, a clear genotype-phenotype correlation is not easily made. H.. Read More»

Direct preparation protocol to obtain mitotic chromosomes from canine mammary tumors
Authors: C.S.D. Morais, P.R.A.M. Affonso, J.A. Bitencourt and A.A. Wenceslau
Currently, mammary neoplasms in female canines are a serious problem in veterinary clinics. In addition, the canine species is an excellent disease model for human oncology because of the biological and genetic similarities between the species. Cytogenetics has allowed further study of the characterization of neoplasms in canines. We hypothesized that the.. Read More»

Molecular cytogenetic assignment of genes to bovine chromosome 5
Authors: Marcos De Donato, Dan S. Gallagher Jr., Cathy Lehn, Clare Gill, Jerry F. Taylor
Seven genes were assigned by molecular cytogenetic methods to bovine chromosome 5. To accomplish this, specific primers were either publicly available or were designed from highly conserved regions of the publicly available mammalian gene sequences. The identity of the amplified segments was verified by sequencing and alignmen.. Read More»

New genomic resources for the honey bee(Apis mellifera L.): development of a deep-coverage BAC library and a preliminary STC database
Authors: J.P. Tomkins, M. Luo, G.C. Fang1, D. Main1, J.L. Goicoechea,M. Atkins, D.A. Frisch, R.E. Page, E. Guzm�¡n-Novoa5, Y. Yu,G. Hunt6 and R.A. Wing
We have constructed a bacterial artificial chromosome (BAC) library for a European honey bee strain using the cloning enzyme HindIII in order to develop resources for structural genomics research. The library contains 36,864 clones (ninety-six 384-well plates). A random sampling of 247 clones indicated an average insert size o.. Read More»

Molecular detection of XO - Turner syndrome
Authors: Carlos Alberto Longui, Mylene Neves Rocha,Liana Carla Albuquerque Peres Martinho,Gustavo Gir Gomes, Ricardo Eustachio de Miranda,Thomas Alves de Souza Lima, M�´nica Barbosa Melo and Osmar Monte
Turner syndrome is caused by haploinsufficiency of the short arm of X-chromosome, and is usually diagnosed by karyotyping. This procedure is time-consuming, expensive and unfeasible for population screening. We propose molecular detection of 45XO Turner patients based on the ability of HpaII, a methylation sensitive endonuclea.. Read More»
