Elaeagnus angustifolia L. is a Eurasian tree that has become naturalized and has various ecological, medicinal and economical uses. In this study, a combination of morphological traits and RAPD markers were used to study the presence or absence of an association between genetic variation and morphological features among five populations of E. angustifolia collected from the East Azarbaijan of I...
pomegranate is an importantly popular fruit crop with iran the main center of its diversity throghout the world. the richest pomegranate genetic resources believed to exist in iran. the present investigation was carried out to study the genetic diversity of 15 genotypes of pomegranate in tarume zanjan making use of rapd markers. genomic dna was extracted from the plant,s leaf, and tested for th...
Phylogeny and genetic diversity of Amphioctopus fangsiao were assessed by sequence analysis of complete mitochondrial genomes, sequenced from 15 individuals of nine populations. The whole mtDNA genomes size were ranging from 15977 to 15990 bp. Data revealed 1642 polymorphic sites and 1023 parsimony informative sites. The phylogenetic analysis based on neighbor joining tree disclosed two clades...
in the regulated nakdong river, algal proliferations are annually observed in some seasons, with cyanobacteria (microcystis aeruginosa) appearing in summer and diatom blooms (stephanodiscus hantzschii) in winter. this study aims to develop two ecological models forecasting future chlorophyll a at two time-steps (one-week and one-year forecasts), using recurrent neural networks tuned by genetic...
background: the tan spot disease of wheat caused by pyrenophera tritici-repentis has become a major disease in most wheat growing areas worldwide. objectives: here we used issr and rapd markers to study the genetic diversity of 34 p. tritici-repentis isolates collected from north of iran.materials and methods: the leaves having the typical symptoms of tan spot disease were collected and after f...
this paper uses integrated data envelopment analysis (dea) models to rank all extreme and non-extreme efficient decision making units (dmus) and then applies integrated dea ranking method as a criterion to modify genetic algorithm (ga) for finding pareto optimal solutions of a multi objective programming (mop) problem. the researchers have used ranking method as a shortcut way to modify ga to d...
The classification of bamboos based on floral morphology and reproductive characters is very hard due to erratic flowering behavior and unusually long reproductive cycle. The application of reliable and effective DNA molecular markers is highly essential to address this problem. In the present investigation, inter-simple sequence repeats (ISSR) markers were employed to study phylogenetic relati...
warning of reducing genetic diversity of abramis brama (berg, 1905) in gilan coast using ssr markers
genetic diversity is one of the three levels of biodiversity. the aim of present study was to compare levels of genetic polymorphism between wild bream populations using seven microsatellite loci. genetic diversity was investigated by studying samples collected from two regions, the coast of chamkhale and bandaranzali of gilan province. a total of seven microsatellite loci (mfw7, mfw26, mcs1eh,...
Recognition of genetic reserves and desirable genes is the basis of breeding programs. So far, in Iran, due to the lack of recognition of genetic resources, a considerable breeding program has not been done on native plants. The study of the genetic diversity of violets as a native plant with ornamental and medicinal uses is the great importance in advancing the breeding goals of this plant. So...
