evaluation of genetic diversity is a considerable approach to screen within indigenous rhizobial population for compatible, highly effective strains, which can be further utilized as rhizobial inoculums. genetic diversity of rhizobium isolates from three clover species grown in soil samples of seven different geographical regions in iran was investigated by repetitive extra genomic palindromic ...

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 ...

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...

This study was conducted to assess the efficacy of SCoT and DAMD molecular markers in genetic diversity  of three moss species and compare them with ISSR marker. Another objective was to evaluate the suitability of these DNA markers in species identification (delimitation) in three moss species, including Neckera complanata, Homalothecium sericeum and Neckera cris...

the aim of this study was to access the genetic differentiation of paraschistura sp. in kheirabad and brim rivers (zohreh river system, persian gulf basin), iran. for this purpose, 60 samples including 30 male and 30 female samples from each river were collected. a total of six microsatellite loci (bbar4, bbar7, ic228, ic230, ic434 and ic720) were used and all of them showed high polymorphism (...

the persian sturgeon, acipenser persicus (borodin, 1897), is an economically important species, which mainly inhabits the caspian sea. however, little is known about its population genetic structure. in this study, variation in nucleotide sequences of the mitochondrial dna (mtdna) control region of wild stock persian sturgeon was determined to assess the genetic diversity among different natura...

The Convention on Biological Diversity (CBD, 1992) recognises three main levels of biodiversity: ‘diversity within species, between species and ecosystems’. Genetic diversity (heritable variation) underpins their ability to react, adapt be resilient, which is particularly crucial at this time climate change, biodiversity loss. Reporting a key aspect the CBD—all Parties must report progress appr...
