Population genetic structure of stellate sturgeon (Acipenser stellatus) in 197 adult specimens from four fishery regions along the Iranian coastline of the southern Caspian Sea was investigated using microsatellite markers. Out of 15 microsatellite primers, 11 loci were produced, in which 10 of them were polymorphic and 1 was monomorph. Totally, 184 alleles were identified and on average 13.1 a...

The binding of antigenic peptide to class II MHC is mediated by hydrogen bonds between the MHC and the peptide, by salt bridges, and by hydrophobic interactions. The latter are confined to a number of deeper pockets within the peptide binding groove, and peptide side chains that interact with these pockets are referred to as anchor residues. T cell recognition involves solvent-accessible peptid...

to assess the genetic relationships between 72 cultivated and 65 wild grapevines in west azerbaijan and in kurdistan, 19 ssr markers were employed. microsatellitic primer pairs amplified, a total of 163 alleles with an average of 8.6 alleles/locus (for cultivars) and 153 alleles with an average of 8.05 alleles/locus (for wild samples). the expected heterozigosity varied from 0.7 in cultivars to...

The Holstein bulls (n=50) were genotyped for bovine lymphocyte antigen (BoLA-DRB3.2) alleles by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP). Genomic DNA was extracted from bull semen using phenol-chloroform method. A two-step PCR was conducted in order to amplify a 284 base-pair fragment of the target gene. Amplicons were digested by RsaI, HaeIII and BstyI ...

Statistical methodology for testing the Hardy–Weinberg equilibrium at X chromosomal variants has recently experienced considerable development. Up to a few years ago, was basically done by applying autosomal test procedures females only. At present, male alleles can be taken into account in asymptotic and exact both bi- multiallelic case. However, current multiple rely on classical full enumera...

recognizing of genetic diversity and genetic potential of each plant species is necessary and essential before any works on breeding program. genetic diversity among five populations of walnut (juglans regia l.) was studied using 11 ssr markers. the marker system produced 77 alleles in a range size of 176-275 bps. the minimum (2) and maximum (11) numbers of alleles were related to genetic locus...

background: myasthenia gravis is an autoimmune disorder of neuromuscular junction characterized by skeletal muscle weakness and fatigability. different genes may control the induction and clinical presentation of this disease. various hla alleles are reported as predisposing or protective genetic elements in myasthenia gravis. objective: the aim of this study was to investigate the probable ass...
