polymorphism of the b-lactoglobulin (b-lg) gene in 101 cows belonging to the holstein herd and a superior cow, producing more than 150 kg milk/day, together with four offsprings was investigated by the polymerase chain reaction-restriction fragment length polymorphism (pcr-rflp) method. in the holstein herd, the alleles a and b of the b-lg gene had frequencies of 0.53 and 0.47, respectively. th...
Sentence determine the stability mechanisms to stress in Agropyron trichophorum at test with four different levels of osmotic potentials resulted from PEG 6000 including 0, -3, -6 and -9 executed in factorial and accidental manner with four interactions in hydroponic environment. Three genotypes of Agropyron trichophorum pasture types were used Arak (3755), Semirom (3.13), and Faridan (4007) an...
Background and objective: Human is the only host of hepatitis C virus. This virus has a positive single stranded RNA and lipoprotein envelop that has 7 confirmed genotypes. According to studies, genotypes 1a, 3a and 1b are the most common genotypes in Iran. No effective vaccine against HCV infection has been developed instead, advances in antiviral treatment using drugs that directly affect spe...
Cryptosporidium spp. and Enterocytozoon bieneusi are two prevalent opportunistic pathogens in humans and animals. Currently, few data are available on genetic characterization of both pathogens in rabbits in China. The aim of the present study was to understand prevalence and genetic characterization of Cryptosporidium spp. and E. bieneusi in rabbits. We collected 215 fecal samples from 150 Rex...
The aims of this study were to compare the promoter sequence of the mannose-binding lectin (cMBL) gene in Iranian native and commercial chicken strains; as well as to compare the cMBL gene expression in crossbred and inbred chickens. In total 79 native (Western Azerbaijan native fowls, WANF) and 49 commercial (Arian Commercial Strain, ACS) birds were reared as parents under same management prac...
An appropriate dose of radiation should be established on target genotypes before large scale mutagenesis undertaken. The objective of this study was to determine an ideal dose of gamma radiation to induce genetic variation in selected cowpea (Vigna unguiculata) genotypes. Seeds of three Namibian released cowpea genotypes were gamma irradiated using seven dozes at the International Atomic Energ...
Background and purpose: Colorectal cancer is one of the most common cancers in the world and Iran. This cancer is a multifactorial disease that is induced by interaction of various genetic and environmental factors. In this study, we investigated the interactions between different environmental factors and candidate polymorphisms of two genes in colorectal cancer X-ray repair cross-complementin...
The association of the prion protein (PrP) gene with susceptibility to scrapie has formed the basis of selection programs aimed at eradicating the disease from sheep populations. Animals are genotyped for the PrP gene and those with the less susceptible genotypes are selected. The objectives of this study were to determine the effectiveness of predicting PrP genotypes by using information from ...
Recent evidence suggests that certain Fc gamma receptor (FcγR) alleles are genetic risk factors for infectious diseases. In this study, we evaluated FcγRIIa polymorphism in patients with brucellosis. In a casecontrol study, the frequency of two alleles and three genotypes for FcγRIIa were measured by PCR in 150 patients with brucellosis and 125 healthy controls. The H131 and R131 alleles were f...
The common fig (Ficus carica L.), one of the most important fruit species, belongs to Moraceae family and is widely distributed in Iran. In this study, genetic variations among some genotypes of common fig collected from six different regions of Ilam province (Iran) were evaluated based on RAPD and ISSR markers. A total of 73 and 29 alleles were produced by 14 RAPD (with their sizes ranging fro...
