Study of genetic variability in pigs after the traditional breeding program

Authors: I.M. Ferreira, G.S. Vieira, T.F. Braga, T.C.F. Silva, M.M. Franco and R.C. Antunes

Molecular markers are tools used to improve genetic gains. The objective of this study was to analyze the security of alleles of molecular marker genes for characteristics of economic interest in a pure population of pigs. After the extraction of DNA from the hair of 272 Large White matrices, the allele and genotype frequency .. Read More»

Evaluation of genome similarities using the non-decimated wavelet transform

Authors: L.M. Ferreira, T. S�¡fadi and R.R. Lima

The wavelets have become increasingly popular in the field of bioinformatics due to their capacity in multiresolution analysis and space-frequency localization; the latter particularity is acquired due to a moving window that runs through the analyzed space. As a feature, they have a better ability to capture hidden components.. Read More»

Genotypic variation and relationships among nitrogen-use efficiency and agronomic traits in tropical maize inbred lines

Authors: M.C. Rodrigues, W.M. Rezende, M.E.J. Silva, S.V. Faria, L.T. Zuffo, J.C.C. Galv�£o and R.O. DeLima

Improvement in nitrogen-use efficiency (NUE) on maize is among the best strategies to mitigate the problems of poor soil fertility in tropical conditions. The objectives of this study were: i) to quantify the genetic variability for NUE-components and agronomic traits in a set of tropical maize inbred lines; ii) to study the g.. Read More»

Contemporary pollen and seed dispersal in natural populations of Bertholletia excelsa (Bonpl.)

Authors: A.B. Baldoni, L.H.O. Wadt, T. Campos, V.S. Silva, V.C.R. Azevedo, L.R. Mata, A.A. Botin, N.O. Mendes, F.D. Tardin, H. Tonini, E.S.S. Hoogerheide and A.M. Sebbenn

Due to the nutritional content and commercial value of its seeds, Bertholletia excelsa is one of the most important species exploited in the Amazon region. The species is hermaphroditic, insect pollinated, and its seeds are dispersed by barochory and animals. Because the fruit set is dependent on natural pollinator activity, g.. Read More»

Interleukin-18 (rs187238) and glucose transporter 4 (rs5435) polymorphisms in Euro-Brazilians with type 1 diabetes

Authors: Y. Al-Lahham, A.K.B. Mendes, E.M. Souza, D. Alberton, F.G.M. Rego, G. Valdameri and G. Picheth

Type 1 diabetes (T1D) is an autoimmune disease with a strong genetic component that has been associated with several genetic loci. Interleukin 18 (IL-18) is a potent proinflammatory cytokine, which is involved in the innate and adaptive immune responses, and in the pathogenesis of various diseases including T1D. Glucose transp..

Chromosome variations and diversity of Epidendrum ibaguense Lindl. (Orchidaceae) on the Tepequ�©mâ��s Tepuy, Roraima, Brazil

Authors: S.R. N�³brega, A.L.F. Coelho, C.F. Verola, I.R. Costa, R. Vila�§a, F.J.F. Luz and W.F. Ara�ºjo

Studies addressing chromosome variations have elucidated many points regarding the taxonomy of the Orchidaceae. Epidendrum L. besides being one the largest orchid genera, present remarkable morphological, and inter- and intraspecific chromosome variations. Thus, based on a previous report on flower color variation in individua.. Read More»
