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...

genetic diversity is a key component of ecosystems. the aim of the present study was to evaluate the genetic diversity of iranian native honeybee colonies (apis mellifera meda l.) located in the northern region. colonies from 24 locations have been analyzed using microsatellite markers. samples were collected from caspian sea southern area (north of iran). six microsatellite markers (a28, a29, ...

The coasts of Imam Khomeini port are one of the most important hot spots of mangrove plantations across Iranian coast of Persian Gulf and Sea of Oman, so this is very important to conserve this valuable ecosystem. For this purpose, 75 individual from 3 populations, keeping the minimum distance of 30 to 50 meters from each other, has been collected and investigated using 15 ISSR markers. This st...

enzyme electrophoresis was used to measure genetic variation within, and divergence among, three generations of recently bred synthetic alfalfa generations (syn1, syn2, and syn3) originating from a polycross of 12 selected parents and several cultivars. three isozyme loci, exhibiting tetrasomic inheritance in 10-day seedlings, were detected from five enzymatic systems analyzed by polyacryla...

the applicability of rapds, aflps, and ssrs to examine genetic relationships in 36 populations of triticum boeoticum from west of iran was investigated. a total of 224 (135 polymorphic), 979 (429 polymorphic) and 246 (145 polymorphic) bands/alleles were detected using 14 rapd primers, 17 aflp primer combinations and 17 well distributed, mapped ssr markers, respectively. the polymorphic informat...

comparative assessment of genetic diversity of 122 durum wheat genotypes (triticum turgidum l. var. durum) was performed using 73 ssap polymorphic fragments, 123 aflp polymorphic loci and 104 ssr alleles. ssap and aflp data showed a clear demarcation between the cultivars and landraces and ssr data classified cultivars and landraces according to their origin. furthermore, the estimated genetic ...

genetic diversity among plants sprouted from seven year old clones of mulberry (morus indica var. s36) was studied using molecular markers such as issr and rapd. the clones showed significant variability in sex expression and the sprouting behavior. these changes were appeared after seven years of rigorous pruning and training (pruned once in every 3-4months). genetic diversity analysis reveale...
