Genetic control of number of flowers and pod set in common bean
Authors: E.S. Martins, R.A. Pinto J�ºnior, A.F.B. Abreu and M.A.P. Ramalho
This article aimed to study the genetic control of some flowers and pod set of common bean and to verify if its estimate varies with environmental conditions and gene pool. A complete diallel was used among six lines, but no reciprocal ones. The treatments were evaluated in three harvests/generations - F2, F3, and F4 - in 2015.. Read More»

Ewes carrying the Booroola and Vacaria prolificacy alleles respond differently to ovulation induction with equine chorionic gonadotrophin
Authors: J.C.F. Moraes and C.J.H. Souza
The magnitude of ovulation rate (OR) after hormonal induction in sheep should be considered when prolific genotypes are used. We investigated for the first time the effect of the Vacaria allele and its combined effect with the Booroola prolificacy mutation on OR after hormonal treatment during breeding and anoestrous season. A.. Read More»

Genetic diversity of Plathymenia reticulata Benth. in fragments of Atlantic Forest in southeastern Brazil
Authors: L.C. Souza, A.L. Silva J�ºnior, M.C. Souza, S.H. Kunz and F.D. Miranda
Studies of genetic diversity in natural populations are important for the definition of conservation strategies, especially in populations reduced by processes of fragmentation and continuous forest extraction. Molecular markers stand out as interesting tools for these studies. The objective of this research was to characteriz.. Read More»

Genetic diversity of Schizolobium parahyba var. amazonicum (Huber ex. Ducke) Barneby, in a forest area in Brazil
Authors: A.L. Silva J�ºnior, L.C. Souza, A.G. Pereira, M.V.W. Caldeira and F.D. Miranda
Schizolobium parahyba var. amazonicum (Fabaceae) is an arboreal species, endemic to the Amazon Rainforest, popularly known as paricá. It is used on a commercial scale in the timber sector, pulp and paper production, reclamation projects in degraded and landscaped areas. However, there is no availability of genetically i..

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»

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»

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..
