different species of streptomyces are common in most types of soil. some certain species are plant pathogenic especially on potato. this study was conducted to evaluate genetic diversity among some local streptomyces spp. strains isolated from soil and infected tubers in potato farms in northwest of iran. repetitive dna elements (box, eric and rep) as genetic markers were used for diversity stu...

objective(s):from the ancient era, emergence of agriculture in the connecting region of mesopotamia and the iranian plateau at the foothills of the zagros mountains, made iranian gene pool as an important source of populating the region. it has differentiated the population spread and different language groups. in order to trace the maternal genetic affinity between iranians and other populatio...

sardari is one of the most important landraces of common wheat (triticum aestivum l.) that is mainly cultivated in drylands and mountainous area of iran. moreover, it shows a high level of genetic diversity. in the present research a total of 73 sardari wheat ecotypes were evaluated for drought tolerance. genetic diversity was analyzed using amplified fragment length polymorphism (aflp) marker ...

little information is available regarding genetic variation in wild wheat relatives from iran. in this study, genetic diversity of 36 populations of wild einkorn wheat, triticum boeoticum, was studied using amplified fragment length polymorphism (aflp) primer combinations. seventeen aflp primer combinations led to amplify 979 scorable fragments ranging from 50 to 500 bp and of these, 429 (44%) ...

iran is a part of the secondary centre of origin of melons, and therefore, there is a wealth of genetic variation of these species in this country. the amplified fragment length polymorphism (aflp) marker was applied to investigate the genetic variations among five major iranian melon cultigens (cucumis melo) and ‘ananasi’ as a general well-known cultivar. ten primer pairs were used on 90 indiv...
