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 ...
In the present study, Randomly Amplified Polymorphic DNA (RAPD) and Repetitive Extragenic Palindromic sequence-based Polymerase Chain Reaction (REP-PCR) were used to characterize 131 isolates of Pasteurella multocida, originating from different healthy and diseased animal species obtained from several geographical regions of Iran. The RAPD and REP-PCR generated amplified products in the range ...

this study aimed to investigate the effects of listening strategy training on iranian efl learners listening comprehension and use of such strategies. this work, employing an experimental methodology, was conducted among 60 adult efl learners from a language institute in isfahan, iran, as participants. the participants, who were selected based on the results of a placement test, were assigned t...
UPGMA analysis, principal component analysis, genetic diversity analysis and genetic distance analysis of RAPD data were used to assess the extent of host specialization in 50 isolates of S. homoeocarpa from five turfgrass hosts. In UPGMA analysis and principal component analysis, the occurrence of host specialization was not readily apparent based on visual inspection. Genetic diversity analys...
abstract sclerotinia sclerotiorum is the causal necrotroph pathogen with wide host range and showed various phenotipic intraspecies variability. considering to difficult identification of intraspecies heterogeneity on the basis of phenotypic factors, compatible mycelium groups introduced as an appropriate tool for classification and intraspecies heterogeneity distinction. in this research, 19 f...
Background and Objective: Protozoan parasites of Leishmania major is one of the causative agents of cutaneous leishmaniasis in different parts of Iran. Currently different molecular biology tools based on different polymorphic DNA sequences have been used in order to investigate heterogeneity among different Leishmania species. Multilocus microsatellite typing method (MLMT) is one of these int...
the major aim of this study was to investigate the relationship between social and cultural capital and efl students’ critical thinking skills. this study takes this relationship in to account to see if people with different sociocultural status are different regarding their critical thinking skills. to this end, 160 university students majoring in english language and literature, english trans...
During the growing seasons of 2009 and 2010, same tomato fields throughout Marvdasht were visited and 96 isolates of Fusarium spp. were collected from root, crown and stem of diseased tomato plants. Isolates were identified as based on morphological characteristics. They were divided into four species namely: Fusarium solani, F. pseudoanthophilum, F. oxysporum and F. equiseti. These species,...
Background & Aims: In recent years, molecular methods for characterizing genetic heterogeneity have found a major place in modern approaches. In this study, two different molecular techniques including Restriction Fragment Length Polymorphism (RFLP) and Multi Locus microsatellite typing (MLMT) were carried out in order to evaluate genetic heterogeneity among isolates of Leishmania major in Iran...
