Selection in sugarcane based on inbreeding depression
Authors: A.A.C. de Azeredo, L.L. Bhering, B.P. Brasileiro, C.D. Cruz and M.H.P. Barbosa
This study aimed to evaluate the gene action associated with yield-related traits, including mean stalk weight (MSW), tons of sugarcane per hectare (TCH), and fiber content (FIB) in sugarcane. Moreover, the viability of individual reciprocal recurrent selection (RRSI-S1) was verified, and the effect of inbreeding depression on.. Read More»

Correspondence between performance of Eucalyptus spp trees selected from family and clonal tests
Authors: C.A.F. Reis, F.M.A. Gon�§alves, L.N. Rosse, R.R.G.F. Costa and M.A.P. Ramalho
We examined the correspondence in performance between trees selected from a family test and their respective clones from a clonal test of Eucalyptus. Full-sib families were obtained from controlled pollination among individuals of Eucalyptus grandis and between E. grandis and E. urophylla. The hybridizations did not follow a f.. Read More»

Genetic parameters for carcass traits and body weight using a Bayesian approach in the Canchim cattle
Authors: S.L.C. Meirelles, F.B. Mokry, A.C. EspasandÃ?Ân, M.A.D. Dias, M.M. Baena and L.C. de A. Regitano
Correlation between genetic parameters and factors such as backfat thickness (BFT), rib eye area (REA), and body weight (BW) were estimated for Canchim beef cattle raised in natural pastures of Brazil. Data from 1648 animals were analyzed using multi-trait (BFT, REA, and BW) animal models by the Bayesian approach. This model i.. Read More»

Change in heritability estimates due to half-sib family selection in the maize variety Pahari
Authors: M. Noor, D. Shahwar, H. Rahman, H. Ullah, F. Ali, M. Iqbal, I.A. Shah and I. Ullah
This research was carried out at the Agriculture Research Farm, Khyber Pakhtunkhwa Agricultural University, Peshawar, and the Cereal Crops Research Institute, Pirsabak, Nowshera, during 2009 and 2010. Half-sib families (HS) derived from the maize variety Pahari in spring crop seasons 2009 and 2010 were developed at the Cereal Crops Research Institute. All.. Read More»

Allelic polymorphism, gene duplication and balancing selection of the MHC class II DAB gene of Cynoglossus semilaevis (Cynoglossidae)
Authors: T.J. Xu*, Y.N. Sun* and R.X. Wang
Major histocompatibility complex (MHC) genes play an important role in the immune response of vertebrates. Allelic polymorphism and evolutionary mechanism of MHC genes have been investigated in many mammals, but much less is known in teleosts. We examined the polymorphism, gene duplication and balancing selection of the MHC cl.. Read More»

Correlations between traits in soybean (Glycine max L.) naturally infected with Asian rust (Phakopsora pachyrhizi)
Authors: B. Rodrigues, F. Serafim, A.P.O. Nogueira, O.T. Hamawaki, L.B. de Sousa and R.L. Hamawaki
Soybean (Glycine max L.)-breeding programs aim to develop cultivars with high grain yields and high tolerance to Asian soybean rust (Phakopsora pachyrhizi). Considering that the traits targeted for breeding are mainly quantitative in nature, knowledge of associations between traits allows the breeder to formulate indirect selection strategies. In this stu.. Read More»

Effective sample selection for classification of pre-miRNAs
Authors: K. Han
To solve the class imbalance problem in the classification of pre-miRNAs with the ab initio method, we developed a novel sample selection method according to the characteristics of pre-miRNAs. Real/pseudo pre-miRNAs are clustered based on their stem similarity and their distribution in high dimensional sample space, respective.. Read More»

Comparison of BLUE and BLUP/REML in the selection of clones and families of potato (Solanum tuberosum)
Authors: C.A. Ticona-Benavente and D.F. da Silva Filho
The use of best linear unbiased prediction/restricted maximum likelihood (BLUP/REML) in perennial crops and animal breeding enhances selection gain. However, its advantage with respect to annual crops is not clear. We compared the BLUP and best linear unbiased estimator selection efficiency in the breeding of various potato generations. This was done by s.. Read More»

Applying the Fisher score to identify Alzheimer�s disease-related genes
Authors: J. Yang, Y.L. Liu, C.S. Feng and G.Q. Zhu
Biologists and scientists can use the data from Alzheimer's disease (AD) gene expression microarrays to mine AD disease-related genes. Because of disadvantages such as small sample sizes, high dimensionality, and a high level of noise, it is difficult to obtain accurate and meaningful biological information from gene expressio..

Cell biology, molecular embryology, Lamarckian and Darwinian selection as evolvability
Authors: H. Hoenigsberg
The evolvability of vertebrate systems involves various mechanisms that eventually generate cooperative and nonlethal functional variation on which Darwinian selection can operate. It is a truism that to get vertebrate animals to develop a coherent machine they first had to inherit the right multicellular ontogeny. The ontogen.. Read More»
