The population structure of Phytophthora capsici among asexual and sexual progenies was analyzed using ISSR. Thirty one parent three populations were assayed for genetic diversity 5 ISSR primers DNA from 120 offspring P. amplified. In total, 71 reproducible fragments obtained, which 100% polymorphic, revealing high polymorphism the isolates. Among them, percentages progeny isolates 100.00 77.46...

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...

Several characteristics of habitats of herbivores and their food-plant communities, such as plant-species composition and plant quality, influence population genetics of both herbivores and their host plants. We investigated how different ecological and geographic factors affect genetic variation in and differentiation of 23 populations of the oligophagous seed predator Lygaeus equestris (Heter...

In this study, Simple Sequence Repeat markers (SSR) were used to investigate the genetic variation between 49 cumin ecotypes collected from 9 different provinces of Iran. SSR primers Elap1479, Elap040 and Elap1493 showed the highest (89%), while Elap1340 and Elap017 showed the lowest (56%) number of polymorphic bands. Polymorphism information content (PIC) values varied between 0.18 - 0.37. The...

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...

Giardia duodenalis is a flagellated intestinal protozoan responsible for infections in various hosts including humans and several wild and domestic animals. Few studies have correlated environmental contamination and clinical infections in the same region. The aim of this study was to compare groups of Giardia duodenalis from clinical and environmental sources through population genetic analyse...

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...
