Background Ghezel sheep are highly prolific and one of the local sheep breeds in Iran and Turkey. Growth differentiation factor-9 (GDF9) gene has been found to be essential for growth and differentiation of early ovarian follicles. Novel mutations in GDF9 have been associated with increased ovulation rates and high litter sizes in heterozygous carriers. Therefore, fecundity gene for GDF9 (FecGH...

Eggshell quality is the main trait to assess egg quality. Marker assisted selection can be used to improve this trait. During eggshell formation, a mass of inorganic minerals is deposited. The Sodium Channel (SCNN1) gene family plays an essential role in cation transportation and SCNN1g is a member of this gene family. The objective of this study was to estimate the frequency of SCNN1g gene var...

the aim of the study was to explore the mechanisms underlying the association of birth weight with later body mass index (bmi) from the biochemical markers related to metabolism and the apa i polymorphism in igf-ii gene.a total of 300 children were selected randomly from the macrosomia birth cohort in wuxi, china. the height and weight were measured and blood samples were collected. plasma conc...

a study was conducted to identify ssr markers linked to leaf rust resistance genes lr24 and lr28 and to be used for marker-assisted selection (mas) to transfer both genes to a widely cultivated wheat variety mp 3299 under rainfed condition. f2 individuals of the cross mp 3299×nil pbw 343 were used for generating genotypic data employing closely linked scar markers s73719 and s421570 to lr24 and...

Homozygous, loss-of-function mutations in the mouse Reelin gene cause a severe neurological phenotype known as reeler. These mutant mice exhibit marked cerebellar hypoplasia, dyslamination of cortical and hippocampal cellular layers, and malposition of specific neuronal populations in the brain stem and spinal cord. Similarly, homozygous mutations in the very conserved human REELIN gene cause a...

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 identification of molecular markers linked to leaf curl virus (clcuv) disease resistance in cotton has the potential to improve both the efficiency and the efficacy of selection in cotton breeding programs. genetic analysis suggested that clcuv resistance is controlled by a single dominant gene. in this study, an interspecific f2 population derived from a cross of gossypium barbadense and g...

In silico 16S ribosomal RNA gene-based restriction enzyme approach is a computer-simulated polymerase chain reaction-restriction fragment length polymorphism analysis method, namely customizable in sequence evaluation for sites. The purpose of this study was to identify lactic acid bacteria using gene (16S polymorphism). An investigation conducted detect species-specific molecular markers diffe...
