there is substantial diversity in achillea biebersteinii plants in iran. it has considerable different biological activities including antibacterial, antifungal, antioxidant, insecticidal, herbicidal and wound healing. research improvement for medicinal plants depends on the available genetic diversity. the assessment of genetic variability could increase the information for breeding programs. ...

Hot pepper (Capsicum spp.) is an economically important spice widely cultivated and consumed in Ethiopia. In spite of its wide importance, there is no information available on the molecular genetic diversity of this crop. Cultivars characterization is an important link between the conservation and utilization of plant genetic resources in various breeding programs. Using five ISSR prim...

Sainfoin (Onobrychis viciifolia Scop.) is a perennial legume widely adapted to environmental conditions and has been successfully used as a pasture and hay forage in Iran. This experiment was carried out to investigate yield potential and genetic variation of morphological, agronomic and qualitative traits using 10 Iranian sainfoin populations. The experiment was conducted as a randomized compl...

In order to study the genetic variation among local varieties of onion in Iran, an experiment was conducted in the Research Center, Faculty of Agriculture, Tabriz University. Sixteen populations were evaluated for agronomic characteristics and also total seed proteins via SDS-PAGE. Cluster analysis and principal component analysis were used to group the onion populations under study. Analysis o...

A qualitative diagnosis of infertility requires attention to female and male physical abnormalities, endocrine anomalies and genetic conditions that interfere with reproduction. Many genes are likely to be involved in the complex process of reproduction. Cystic fibrosis (CF) incidence varies in different White people populations (a higher incidence of CF is observed in northern–western European...

Ferulago angulata subsp. carduchorum (Boiss. & Hausskn.) D.F. Chamb is a perennial species of the family Apiaceae and is locally used as a flavouring agent and for some medicinal properties. The essential oil of this plant if found to possess antibacterial and antifungal activities. The present study is aimed to determine constituents of essential oils from inflorescence of four F. angulata sub...

Most of the research on Phragmites australis is restricted to sites on the European continent even though P. australis occurs abundantly in many regions in the Asian and other continents under different climatic and habitat conditions. The populations used in this study were collected from different parts of Iran. All these populations were grown in the same conditions in experimental field, lo...

In the present study, mitochondrial DNA polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay was used to assess the population structure and genetic relationships among six Persian sturgeon, Acipenser persicus populations from south Caspian Sea along the Iranian coast. The complete nucleotide dehydrogenase subunit 5 (NADH 5) region of mtDNA amplified by PCR was di...

This study represents a large-scale population genetic analysis of the stellate sturgeon, Acipenser stellatus, in the Caspian Sea. In total, 192 samples of adult stellate sturgeon were collected from four commercial catch stations in the Northern (Volga and Ural Rivers) and Southern Caspian Sea (estuary of Sefidrud and Gorganrod Rivers-Iran). Fifteen sets of microsatellite primers developed fro...
