lactoferrin is a glycoprotein with molecular weight 80 kda iron-binding bond, which is composed of 690 amino acids. in most mammalian body fluids such as sweat, semen, tears, and saliva and milk neutrophil granules there. bovine lactoferrin gene be associated with susceptibility/resistance to mastitis and even with some economically important production traits. this study was carried out to det...

Quantitative traits locus for milk production traits has been described on centromeric end of bovine chromosome 14. Reports name the acyl coA: diacylglycerol acyltransferase (DGAT1) gene as a potential candidate gene with dinucleotide substitution (AA to GC) in exon VIII which causes the change of lysine to alanine in amino acid (K232A).The aim of the present study was to estimate the frequency...

The GH gene and BMP15 gene have been used as candidate genes for ­marker-assisted selection in different livestock species. Random blood samples were obtained from 180 Zel sheep breed to study genetic polymorphism of these genes. DNA was extracted from blood samples and a 365 bp fragment from the exon V of the ovine growth hormone gene and a 312 bp region from exon II of BMP15 gene were amplifi...

this study was conducted to detect polymorphism of gene bmp15, a member of transforming growthfactor β (tgfβ) family which has a crucial role in controlling the ovarian follicles development,ovulation rate and fertility. samples were randomly selected from 91 najdi goats in 3 geographicallocations, northwest, southeast and center of khuzestan province. after dna extraction, amplification of235 ...

seven maize inbred lines were crossed in a complete diallel cross design at the seed and plant improvement institute, karaj, iran, during the 2006 growing season. the parents and 42 f1 hybrids were grown in the research field of islamic azad university of firoozabad, firoozabad, iran, using a randomized complete block design (rcbd) with three replications, during the 2007 growing season. the ha...

It has been more than half a century that plant geneticists and breeders have been trying to assemble a combinationof genes in crop plants, in order to make them as suitable and productive as possible. Plant transformation technology incrop plants was first undertakenin the 1980s based on the ability of foreign gene integration into host plant genome andregeneration of transformed plant cells i...

In many machine learning applications, one must perform feature selection in order to obtain good classification performance. For example, selecting a good feature subset is critical when the sample size is small compared with the dimesionality and noise in the observations. When this is the case, it is necessary to reduce the number of features to avoid modeling noise in the classifier. When t...

UNLABELLED Selection of significant genes via expression patterns is an important problem in microarray experiments. Owing to small sample size and the large number of variables (genes), the selection process can be unstable. This paper proposes a hierarchical Bayesian model for gene (variable) selection. We employ latent variables to specialize the model to a regression setting and uses a Baye...
