Survival of the thriftiest: restricted nurture reveals the thrifty nature of a growth gene in Bos indicus
Authors: S.U. Dani, M.A.C. Dani, I.L. Freire, S.P. Gouvea, F.B. Knackfuss, F.P. Lima, M.E.Z. Mercadante, E. Monteiro, S.M.G. Paggiaro, A.G. Razook and H.C. Yehia
Growth hormone (GH) is a part of the somatotropic axis that controls metabolism, growth, development and aging in a wide range of animals. Mutations that reduce GH signaling have been associated with extended life spans and increased longevity in ways similar to what is observed in dietary restriction (DR) models. However, the..

Problems with and a system to eliminate single-primer PCR product contamination in simple sequence repeat molecular marker-assisted selection in soybean
Authors: J. Ma, S.C. Guan, D. Yao, Y.F. Wei and P.W. Wang
Polymerase chain reaction (PCR) provides a foundation for simple sequence repeat molecular marker-assisted selection (SSR MAS) in soybean. This PCR system and its various conditions have been optimized by many researchers. However, current research on the optimization of the PCR system focuses on double-primer PCR products. We..

Evaluation of progenies from the fifth reciprocal recurrent selection cycle in maize
Authors: N.B. Alves, J.M.V. P�¡dua, K.O.G. Dias, R.P. Diniz, M.L. Guedes, G.A. Cardoso and J.C. Souza
The objective of this study was to evaluate the performance of 119 full sib progenies of the fifth cycle of reciprocal recurrent selection (RRS) derived from of Universidade Federal de Lavras maize breeding program. The experiment was carried out in an 11 x 11 triple lattice design at two locations (Lavras, Lambari). The plots consisted of two rows of 3 m.. Read More»

Synergistic and threshold effects of GH1 and GHR promoter size variation on body growth and fat accrual in young Nelore (Bos indicus) bulls
Authors: M.A. Dani, M. von Cube, I.L. Freire, L. Suguisawa, C. Fischer, S.U. Dani
A synergistic effect in the somatotropic axis (GH1-GHR-IGF1) was observed in 736 young Nelore (Bos indicus) bulls under ad libitum grass feeding conditions on irrigated pasture in central Brazil. Stepwise substitution of shorter alleles of the promoter region of the growth hormone gene (GH1) and the P1 promoter of the GH1 rece.. Read More»

Identifying differences in protein expression levels by spectral counting and feature selection
Authors: P.C. Carvalho, J. Hewel, V.C. Barbosa and J.R. Yates III
Spectral counting is a strategy to quantify relative protein concentrations in pre-digested protein mixtures analyzed by liquid chromatography online with tandem mass spectrometry. In the present study, we used combinations of normalization and statistical (feature selection) methods on spectral counting data to verify whether.. Read More»

Development of SNP-based dCAPS markers for identifying male sterile gene tms5 in two-line hybrid rice
Authors: F.S. Song, J.L. Ni1, Y.L. Qian, L. Li, D.H. Ni and J.B. Yang
Molecular markers can increase both the efficiency and speed of breeding programs. Functional markers that detect the functional mutations causing phenotypic changes offer a precise method for genetic identification. In this study, we used newly derived cleaved amplified polymorphic sequence markers to detect the functional mu.. Read More»

From unicellularity to multicellularity - molecular speculations about early animal evolution
Authors: H.F. Hoenigsberg, M.H. TÃ?Âjaro and C. Sanabria
A morphological, physiological, developmental, and genetic organization of great complexity ineluctably unfolded from relatively simple phenomena invested with enormous potential. Sometime long ago in the Protererozoic times, parasitic invasions caused lower evolutionary levels to integrate into higher-level selection. Therefore, we have a multi-level sel.. Read More»

Gene selection based on multi-class support vector machines and genetic algorithms
Authors: Bruno Feres de Souza and Andr�© Ponce de Leon F. de Carvalho
Microarrays are a new technology that allows biologists to better understand the interactions between diverse pathologic state at the gene level. However, the amount of data generated by these tools becomes problematic, even though data are supposed to be automatically analyzed (e.g., for diagnostic purposes). The issue become.. Read More»

Studies of genetic effects of early selection of maize based on seed quality traits are rare, especially those that use materials from different heterotic groups. These studies are also useful in tropical environments and for the advancement of sustainable agriculture with cropping during seasons not commonly used for cultivat.. Read More»

Genetic analysis of average annual productivity of Nellore breeding cows (COWPROD)
Authors: J.P. Eler, J.B.S. Ferraz, J.C.C. Balieiro and E.C. Mattos
With the aim of estimating the coefficient of heritability of average annual productivity of Nellore cows (COWPROD), a data set from 24,855 animals with known pedigree was analyzed. COWPROD is defined as the amount (in kilograms) of weaned calves produced yearly by one cow during her remaining time in herd ignoring a fixed.. Read More»
