in this study, genetic diversity of 20 wheat genotypes was evaluated using 126 simple sequence repeats (ssr) alleles, covering all three wheat genomes. a total of 1557 allelic variants were detected for 126 ssr loci. the number of alleles per locus ranged from 4 to 19 and the allelic polymorphism information content (pic) varied from 0.66 (xgwm429) to 0.94 (xgwm212 and xgwm515). the high­est po...

the aim of this research was to study two alleles bf2*13, bf2*21 of bf2 gene in class i mhc in two population at sistan and baluchestan province. mhc is a gene cluster that play regulation role in immune system. many experiments showed association between the gene cluster and resistance and sensitiveness against different diseases and, also productivity traits. bf2 gene is among associated loci...

Background: Different studies have demonstrated that a small proportion of healthy individuals receiving the hepatitis B (HB) vaccine do not produce protective levels of anti-HB antibody, a phenomenon which could be linked to certain human leukocyte an-tigen (HLA) class-II alleles or haplotypes. Objectives: The present study was under-taken to determine the frequency of HLA class-II alleles in ...

Background:It has been hypothesized that genetic factors other than histocompatibility disparity may play a role in predisposition to developing Chronic Myelogenous Leukemia (CML). In this regard, Th1 and Th2 cytokines and their gene polymorphism seems to be important. Overall expression and secretion of cytokines is dependent, at least in part, on genetic polymorphism (nucleotide variations) w...

Objective: This study aimed to investigate the association between HLA alleles and visceral leishmaniasis (VL) in a sample of Iraqi patients. Methods: A total of 30 patients were studied, in addition to 20 age, gender and ethnicity matched controls. All subjects were genotyped by polymerase chain reaction-sequence specific primers (PCR-SSP) method. Results: For HLA-class I region (A and B loci)...

background and objective: the outcome of hepatitis b virus (hbv) infection may be influenced by host factors like human leukocyte antigen (hla). we have investigated hla-a and drb1 alleles in patients with persistent hepatitis b infection compared to subjects who had spontaneously recovered from hbv infection. to complete the findings of this study we performed another survey in certain hla all...

potential relationships between amino acid motifs in the antigen binding groove of various alleles of the bovine major histocompatibility complex dr (bola-dr) molecule and peripheral blood mononuclear cell (pbmc) proliferation, in response to s. aureus and phytohemaglutinin, were investigated. the animals included in the study were approximately of the same age and comprised of pure holstein-fr...

pistacia atlantica subsp. mutica is one of the most valuable forest tree species in iran that has been severely exploited for a long time. therefore, understanding the genetic diversity of different populations can be an important step towards the development and restoration of the habitat of this invaluable tree species. in this study, in order to study the genetic diversity, 10 populations in...
