Digital image analysis to quantify genetic divergence in passion fruit seeds

Authors: Leandro Rafael Fachi, Willian Krause, Henrique Duarte Vieira, Dejânia Vieira de Araújo, Petterson Baptista da Luz, Alexandre Pio Viana

Phenotyping through digital images has been used to evaluate morphological characteristics of seeds, providing fast, accurate results. The objective of this work was to estimate the genetic divergence among full-sibling families of passion fruit through morphophysiological characteristics of seeds using the Ward-MLM method. Seeds of 98 full-sibling famili.. Read More»

Expression of lipid metabolism and myosin heavy chain genes in pigs is affected by genotype and dietary lysine

Authors: RC Veloso, PS Lopes, MS Duarte, FF Silva, A Saraiva, ML Chizzotti, W Silva and SEF Guimarães

Expression of lipid metabolism and myosin heavy chain genes was evaluated in skeletal muscle of pig’s genotypes submitted to different dietary digestible lysine contents. Fifty-two barrows and fifty gilts from three genotypes (G: Piau, Duroc and Pietrain crossbreds) were assigned to three dietary digestible lysine conten.. Read More»

Single Nucleotide Polymorphisms associated with growth and carcass traits located on QTL Regions previously associated with Bovine Respiratory Disease

Authors: S. Mizell, S.L. Miller, A.M. Royer, K.J. Thornton, and M.D. Garcia

The objective of the current study was to evaluate single nucleotide polymorphisms (SNP) for potential growth and carcass trait associations located in two previously described quantitative trait loci (QTL) regions associated with bovine respiratory disease. A population of 323 crossbred steers sired by five purebred sire bree.. Read More»

Diversity among elephant grass genotypes using Bayesian multi-trait model

Authors: D.A. Rossi, R.F. Daher, T.C. Barbé, R.S.N. Lima, A.F. Costa, L.P. Ribeiro, P.E. Teodoro and L.L. Bhering

Elephant grass is a perennial tropical grass with great potential for energy generation from biomass. The objective of this study was to estimate the genetic diversity among elephant grass accessions based on morpho-agronomic and biomass quality traits and to identify promising genotypes for obtaining hybrids with high energet..

Cotton genotypes selection through artificial neural networks

Authors: E.G. Silva Júnior, D.B.O. Cardoso, M.C. Reis, A.F.O. Nascimento, D.I. Bortolin, M.R. Martins and L.B. Sousa

Breeding programs currently use statistical analysis to assist in the identification of superior genotypes at various stages of a cultivar’s development. Differently from these analyses, the computational intelligence approach has been little explored in genetic improvement of cotton. Thus, this study was carried out wit.. Read More»

Genotypic gain with simultaneous selection of production, nutrition, and culinary traits in cowpea crosses and backcrosses using mixed models

Authors: D.G. Oliveira, M.M. Rocha, K.J. Damasceno-Silva, F.V. Sá, L.R.L. Lima, and M.D.V. Resende

The aim of this study was to estimate the genotypic gain with simultaneous selection of production, nutrition, and culinary traits in cowpea crosses and backcrosses and to compare different selection indexes. Eleven cowpea populations were evaluated in a randomized complete block design with four replications. Fourteen traits .. Read More»

Effects of cell death-inducing DFF45-like effector B on meat quality traits in Berkshire pigs

Authors: G.E. Yu, S. Kwon, J.H. Hwang, S.M. An, D.H. Park, D.G. Kang, T.W. Kim, I.-S. Kim, H.C. Park, J. Ha and C.W. Kim

Cell death-inducing DFF45-like effector (CIDE) B is a member of the CIDE family of apoptosis-inducing factors. In the present study, we detected a single nucleotide polymorphism (SNP), c.414G>A, which corresponds to the synonymous SNP 414Arg, in CIDE-B in the Berkshire pigs. We also analyzed the relationships between the CI.. Read More»

Comparison of methods for high quantity and quality genomic DNA extraction from raw cow milk

Authors: T. Usman, Y. Yu, C. Liu, Z. Fan and Y. Wang

Isolation of sufficient quantities of high quality DNA is a prerequisite for molecular studies. Milk somatic cells can be used; however, inhibitors such as fats and proteins make milk a difficult medium for extracting large amounts of quality DNA. We optimized, evaluated and compared three methods, Modified Nucleospin Blood Ki.. Read More»

Antioxidant capacity and meat quality of broilers exposed to different ambient humidity and ammonia concentrations

Authors: F.X. Wei, X.F. Hu, R.N. Sa, F.Z. Liu, S.Y. Li and Q.Y. Sun

To investigate the effect of humidity and ammonia on the antioxidative capacities and meat qualities of broilers, 192 broilers were divided into 2 groups: high (H, 70 ppm) and low (L, 30 ppm) ammonia concentration. These groups were divided into 30% (Treatment humidity, T) and 60% (Control humidity, C) humidity, giving 4 treat.. Read More»

Association of SIRT2 gene polymorphisms with body measurement and growth traits of Qinchuan cattle

Authors: L.S. Gui, W.C. Yang, C.P. Zhao, S.J. Wei, Z.D. Zhao and L.S. Zan

Silent information regulator 2 (SIRT2), a member of the Sirtuin family of class III nicotinamide adenine dinucleotide-dependent protein deacetylases, plays an important role in senescence, metabolism, and apoptosis. This study was conducted to detect potential polymorphisms of the bovine SIRT2 gene and explore their relationships with meat quality and bod.. Read More»
