The genetic diversity of 20 Iranian populations of Bunium persicum has been evaluated with random amplified polymorphic DNA (RAPD) and amplified fragment length polymorphism (AFLP) markers. Fresh leaves of seedlings from each population were used for genomic DNA extraction. Analysis of banding patterns of 15 RAPD primers and 17 AFLP primer combinations, revealed 192 (86%) and 228 (75%) polymorp...

Narrow genetic variability may lead to genetic vulnerability of field crops against biotic and abiotic stresses which can cause yield reduction. In this study a set of 37 wheat microsatellite markers linked with identified QTLs for salinity tolerance were used for the assessment of genetic diversity for salinity in 30 promising lines of hexaploid bread wheat (Triticum aestivum L.). A total of 4...

Grapevine (Vitis vinifera L.) is a clonally propagated major fruit crop. In grapevine, identification of genotypes with amplographical features is often based on mature plant characteristics that may be affected by environmental conditions. This approach lacks objectivity and reliability. Recently, molecular markers have proved to be supplementary techniques to analyze genetic diversity and exa...

Identification and classification of genetic source are important in plant breeding and genetic diversity. In order to evaluate genetic diversity of 48 Facultative wheat genotypes belong to north of IRAN, an experiment was done using 10 ISSR primers in the genetic laboratory of Gonbad Kavous University. Out of 62 produced fragments, 41 fragments were polymorphic. The number of polymorphic bands...

Haloxylon salicornicum (Moq.) Bunge ex Boiss is a shrub that grows in large parts of the central regions of Iran. Due to the high adaptability of this species to the severe environmental conditions and its importance in the stabilization of sand dunes, Dust control and medicinal functions recognition of its genetic diversity and the selection of superior genotypes is very important. A set of ...

The advent of integrated microsystems for genetic analysis allows the acquisition of information at unprecedented length and time scales. The convergence of molecular biology, chemistry, physics, and materials science is required for their design and construction. The utility of the microsystems originates from increased analysis speed, lower analysis cost, and higher parallelism leading to inc...

huntingtons disease (hd) is an autosomal dominant inherited disease characterized by involuntary movements, behavioral and personality changes, dementia and cognitive decline. although the mean age of onset is about 40 years, it varies from 5 to 79 years. therefore, at-risk individuals are never sure to have escaped the disease. hd is a member of the growing family of neurodegenerative disorder...
