Authors: R.A.R. Silva, C.G. Fajardo and F.A. Vieira
The aim of this study was to investigate the mating system and genetic diversity of the palm Copernicia prunifera using inter-simple sequence repeat markers. We found that the C. prunifera has multiple inflorescences with hermaphroditic flowers and pollen viability of 62%. Outcrossing rates at the population level (N = 267) pr.. Read More»

Association between gastrointestinal cancers and fingerprint patterns in the Iranian population
Authors: S. Abbasi and M. Rasouli
Gastrointestinal cancers are malignant diseases with high mortality rate. Early diagnosis of patients could improve the results of treatment. Many studies used dermatoglyphics as a biomarker to predict the incidence of genetic diseases and cancers. This study assessed the association between gastrointestinal cancers and partic.. Read More»

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..

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»
