four saudi arabian indigenous sheep populations including najdi, hbsi, arb, and naemi were genotyped for 16 microsatellite markers recommended by the food and agriculture organization (fao). this study aims to provide information on the genetic structure of the breeds analyzed and give indications and proposals for the cross breeding program. all loci were polymorphic in all populations and loc...

beta-lactoglobulin (lgb) is one of the proteins in the mammals’ milk synthesized by the epithelial cells of the mammary glands and affects the quality and coagulation of the milk. the aim of this study was to determine allele frequencies in lgb gene of native and holstein cattle in kerman province using pcr-rflp method. genetic polymorphism, for 100 dna samples in the locus was determined by di...

This study was conducted in order to investigate genetic diversity and population structure of pike-perch in the Northern part of Iran. For this purpose, 207 adult pike-perches from four regions of the Caspian Sea watershed (Talesh Coasts, Anzali Wetland, Chaboksar Coasts and Aras Dam) were collected. DNA was extracted and by using 15 pairs of microsatellite primers, Polymerase Chain Reaction (...

Chickpea (Cicer arietinum L.) is one of the most important legume crops in Iran. Wilt disease caused by Fusarium oxysporum f. sp. ciceri, is the most important soil-borne disease of chickpea in the world. This disease caused high losses in different regions during recent years. Simple sequence repeat (SSR) were used to estimate genetic diversity in 114 of F. oxysporum isolates from six counties...

Accessory gene regulator (agr locus) is a global regulator of many virulence gene expressions inStaphylococcus aureus. Four interference classes related to genetic polymorphisms in the agr locus have sofar been described. In the present study, the agr locus specificity groups were studied within a total of 43 S.aureus isolates which were isolated from ewes with mastitis in three regions in the ...

c-c motif chemokine 22 (ccl22) c16a genetic variation (rs4359426) and c-c chemokine receptor type 4 (ccr4) c1014t variation (rs2228428) have been suggested to affect the expression level of the cognate proteins. here we tried to investigate the plausible association of these polymorphisms with development of colorectal cancer. 165 patients with colorectal adenocarcinoma (age 54.4±13.4) and 150 ...

As a prelude to discovery of genes involved in floral dimorphism and incompatibility, a genetic map of distylous Turnera was constructed along with a fine-scale map of the S-locus region. The genetic map consists of 79 PCR-based molecular markers (48 AFLP, 18 RAPD, 9 ISSR, 4 RAMP), 5 isozyme loci, one additional gene, and the S-locus, spanning a total distance of 683.3 cM. The 86 markers are di...

Many common diseases are known to have genetic components, but since they are non-Mendelian, i.e. a large number of genetic factors affect the phenotype, these components are difficult to localize. These traits are often called complex and analysis of siblings is a valuable tool for mapping them. It has been shown that the power of the affected relative pairs method to detect linkage of a disea...
