macrophomina phaseolina is an important soil-borne pathogen causing charcoal rot in many important crop plants including sesame, in iran. a total of 60 isolates of m. phaseolina were collected from the main sesame producing regions in ten provinces of iran. the genetic diversity among m. phaseolina populations was estimated using inter-simple sequence repeat (issr), focusing particularly on geo...

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%) ...

In order to investigate the variation within and among populations of Parrotia persica C.A. Meyer based on leaf morphological traits, three populations were selected from Behshar area, in the east of Mazandaran Province. The populations selected along a transect in different altitudes of 182, 340, 540 meter above the sea level, respectively. In each population, 10 trees were selected and some l...

inter simple sequence repeat (issr) analysis was performed to evaluate genetic diversity and genetic structure of six capoeta trutta populations from two main watersheds in the kurdistan province. fish samples were caught from the choman, shooei, garmab rivers in the choman watershed and from the gheshlagh, gavarood, sirvan rivers in the sirvan watershed. from six used dinucleotide primers, thr...

population dynamics of three main alfalfa aphids, namely: pea aphid, acyrthosiphon pisum (harris), spotted alfalfa aphid, therioaphis trifolii forma maculata (buckton), black alfalfa aphid, aphis craccivora koch, and their most abundant predators and parasitoids in three sites and in two subsequent years in isfahan, iran, were investigated. the results revealed that frequency and temporal occur...

Some populations of Gundelia tournefortii were compared based on chemotaxonomical characteristics. In this study, some biochemical compounds such as total protein and storage proteins of shoot were studied. The populations were compared on the basis of biochemical characteristics using statistical methods. Different populations were collected from mountains of west Azarbaijan province. Total pr...
