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...

leaf blotch disease of barley, caused by rhynchosporium secalis is a major disease of barley in iran. its worldwide occurrence and economic importance in barley production has motivated studies on the population genetic structure of this pathogen. random amplified polymorphic dna (rapd) method was utilized to investigate the genetic diversity of populations of r. secalis isolated from barley le...

randomly amplified polymorphic dna (rapd) markers were used to analyze genetic stability of the somatic embryogenesis-derived regenerants (r1-6) and mother plant in iranian date palm (phoenix dactylifera l.) cultivar khanizi. total genomic dna extracted from in vitro fresh leaves of regenerated plants and mother plant was amplified using 10-mer oligonucleotide fermantas primers. four primers of...

recommender systems (rs) provide personalized recommendation according to user need by analyzing behavior of users and gathering their information. one of the algorithms used in recommender systems is user-based collaborative filtering (cf) method. the idea is that if users have similar preferences in the past, they will probably have similar preferences in the future. the important part of col...

the common reed (phragmites australis) is a perennial weed with the largest geographical distribution of any flowering plant in the world. in this study, 39 populations of common reed were collected and random amplified polymorphic dna (rapd) markers were used to characterize the genetic diversity among these populations. the 16 primers used in this study, amplified 149 scorable rapd bands amon...

Randomly amplified polymorphic DNA (RAPD) markers were used to analyze genetic stability of the somatic embryogenesis-derived regenerants (R1-6) and mother plant in Iranian date palm (Phoenix dactylifera L.) cultivar Khanizi. Total genomic DNA extracted from in vitro fresh leaves of regenerated plants and mother plant was amplified using 10-mer oligonucleotide Fermantas primers. Four primers of...
