fifteen microsatellite markers were employed to evaluate genetic relationships among different iranian species of crocus spp. (c. sativus, c. haussknechtii, c. cancellatus, c. speciosus, and c. caspius) from ten geographical regions (ghaen, gonabad, estahban, ferdows, veresk, reno, ali abad, kali abad, neka, and eslam abad). of these, 12 primers revealed polymorphism among crocus spp. average p...

Investigating genetic diversity in plant species provides a platform for further insight in plant breeding and conservation. Therefore, in the present study genetic diversity of 13 geographically isolated genotypes of Zhumeria majdea, as a seriously endangered medicine plant growing exclusively in Hormozgan province (South of Iran) was studied. To do so, the leaf samples of Z. majdea were colle...

genetic drift of germplasm in cultivated wheat is good motivation for studying genetic diversity in its wild relatives. in this study, r-rap, a new retrotransposon-based marker, was applied to assess the structure and genetic diversity of 30 accessions of aegilops sp. originating from different geographical regions of iran. the 15 r-rap primer combinations revealed a total of 338 bands ranging ...

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...

Background and objectives: The genus Ephedra (Ephedraceae) consists of about 40 species of mostly shrubs and rarely small trees around the world. In the present study, the essential oil (EO) diversity and genetic relationships were investigated in six Ephedra species from Iran using Random Amplified Polymorphic DNA (RAPD) markers. Methods: The...

Invasive species are one of most significant factors in human-influenced global change. Management actions that prevent the spread and impacts of invasive species require knowledge of their ecological and genetic characteristics. The genetic characteristics of the invasive wine raspberry, Rubus phoenicolasius Maxim. (Rosaceae) and the native sawtooth blackberry, Rubus argutus Link, were examine...

Molecular markers have proven to be invaluable tools for assessing plants’ genetic resources by improving our understanding with regards to the distribution and the extent of genetic variation within and among species. Recently developed marker technologies allow the uncovering of the extent of the genetic variation in an unprecedented way through increased coverage of the genome. Markers have ...

Species are the units used to measure ecological diversity and alleles are the units of genetic diversity. Genetic variation within and among species has been documented most extensively using allozyme electrophoresis. This reveals wide differences in genetic variability within, and genetic distances among, species, demonstrating that species are not equivalent units of diversity. The extent to...
