Genome-wide identification and evolutionary analysis of nucleotide-binding site-encoding resistance genes in Lotus japonicus (Fabaceae)
Authors: H. Song, P.F. Wang,T.T. Li, H. Xia,S.Z. Zhao, L. Hou,C.Z. Zhao
Nucleotide-binding site (NBS) disease resistance genes play a crucial role in plant defense responses against pathogens and insect pests. Many NBS-encoding genes have been detected in Lotus japonicus, an important forage crop in many parts of the world. However, most NBS genes identified so far in L. japonicus were only partia..

Authors: R.D. Castro1, L.A. Peternelli1, M.D.V. Resende2, C.D. Marinho1, P.M.A. Costa1, M.H.P. Barbosa3 and E.F.A. Moreira1
The objective of this study was to assess the efficiency of a modification of the simulated individual best linear unbiased prediction (BLUPIS) procedure, which is used for the approximation of classic individuals (BLUPI) for selection between and within sugarcane families. A total of 110 full-sib families were employed in an experiment initiated in 2007 .. Read More»

Brazilian Nelore cattle: a melting pot unfolded by molecular genetics
Authors: M.A.C. Dani1, M.B. Heinneman2 and S.U. Dani1
The aim of the present article was to study the population structure and genetic diversity of Nelore cattle and genetic relationships between Nelore and different taurine and zebu breeds raised in Brazil. DNA polymorphism analysis was carried out with 1976 animals of 16 zebu, taurine and synthetic breeds raised in Brazil. A higher genetic differentiation .. Read More»

Comparison of methods used to identify superior individuals in genomic selection in plant breeding
Authors: L.L. Bhering, V.S. Junqueira, L.A. Peixoto, C.D. Cruz and B.G. Laviola
The aim of this study was to evaluate different methods used in genomic selection, and to verify those that select a higher proportion of individuals with superior genotypes. Thus, F2 populations of different sizes were simulated (100, 200, 500, and 1000 individuals) with 10 replications each. These consisted of 10 linkage groups (LG) of 100 cM each, cont.. Read More»

Genomic breeding value prediction for simple maize hybrid yield using total effects of associated markers, under different imbalance levels and environments
Authors: N.F. Cantelmo1, R.G. Von Pinho2 and M. Balestre3
The main objective of a maize breeding program is to generate hybrid combinations that are more productive than those pre-existing in the market. However, the number of parents, and consequently the number of crosses, increases so rapidly that the phenotypic evaluation of all the possible combinations becomes economically and technically infeasible. In th.. Read More»

Genetic variation and balancing selection at MHC class II exon 2 in cultured stocks and wild populations of orange-spotted grouper (Epinephelus coioides)
Authors: Z.N. Meng S. Yang B. Fan L. Wang H.R. Lin
Major histocompatibility complex (MHC) molecules play vital roles in triggering adaptive immune responses and are considered the most variable molecules in vertebrates. Recently, many studies have focused on the polymorphism and evolution mode of MHC in both model and non-model organisms. Here, we analyzed the MHC class II exon 2-encoding Ã?² chain in compa..

Selection of putative Terra Maranh�£o plantain cultivar mutants obtained by gamma radiation
Authors: R.V. Reis, E.P. Amorim, C.A.S. Ledo, R.K.N. Pestana, Z.S. Gon�§alvesand A. Bor�©m
The aim of this study was to select putative Terra Maranhão plantain cultivar mutants obtained by gamma radiation, with good agronomic traits and short height. A total of 315 buds were irradiated in vitro with gamma rays in doses of 20 Gy and were subcultivated and evaluated in the field over 2 production cycles. The clones were evaluated to select..

Indirect selection for resistance to ear rot and leaf diseases in maize lines using biplots
Authors: G.S. Pereira, R.B. Camargos, M. Balestre, R.G. Von Pinho and W.M. C. Melo
Leaf disease and ear rot have caused reductions in maize yield in Brazil and other producer countries. Therefore, the aims of this study were to analyze the association between husked ear yield and the severity of maize white spot, gray leaf spot, helminthosporium, and ear rot caused by Fusarium verticillioides and Diplodia maydis using biplots in a mixed..

Implications of the progeny x environment interaction in selection index involving characteristics of the common bean
Authors: L.K. Lima M.A.P. Ramalho A.F.B. Abreu
Breeders normally select simultaneously for several traits in various environments. We investigated the effects of the progeny x environment interaction on success in selection for several traits. The population used was obtained from a cross between the CVIII-85-11 line, which has a semi-erect to prostrate plant architecture and a cream with brown streak.. Read More»

Updates and perspectives on the utilization of molecular makers of complex traits in rice
Authors: G. Li S.W. Kwon Y.J. Park
After complete sequencing of its genome and annotation of the majority of its ~32,000 genes, rice genome has become the model genome among the cereal genomes, and the focus has shifted from structural to functional genomics and application of genomic-derived information in rice breeding. During the past 2 decades, intensive worldwide efforts have led to s.. Read More»
