Estimation of genetic diversity and evaluation of plant germplasm is the most important step in collection and management of plant genetic resources. Also, comparison of different DNA-based genetic markers in diversity evaluation and then advising the most efficient markers is very important. In order to investigate genetic variation among Persian oak (Quercus brantii Lindi.) populations of Lor...
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
BACKGROUND Gymnema sylvestre, a vulnerable plant species, is mentioned in Indian Pharmacopeia as an antidiabetic drug. OBJECTIVE Study of genetic and chemical diversity and its implications in accessions of G. sylvestre. MATERIALS AND METHODS Fourteen accessions of G. sylvestre collected from Central India and assessment of their genetic and chemical diversity were carried out using ISSR (i...
in recent years, several plant species have been used as bioindicators, and several tests have been developed to evaluate the toxicity of the environmental contaminants. in this study, the root length and dna band pattern of root tips in maize (zea mays l.) seedlings were exposed at different concentration of cadmium pollutant (40 and 80 mg l−1). the results indicated that the root length of ma...
In this study, in order to know the variability for a rootstock breeding program genetic diversity and relationships among 55 Iranian almond genotypes and seven related Prunus species were investigated. Morphological and molecular analyses were used. Principal component analysis showed that three components explained 67.6% of the total morphological variation for the first year and 68.06% for t...
Microsatellite DNA markers isolated from wild species khinjuk (Pistacia khinjuk Stocks.) were used to evaluate the genetic diversity available in Iranian pistachio cultivars. Out of the 27 SSR primers tested initially, 25 could amplify the DNA in different pistachio cultivars, of which 19 primer pairs produced clear bands. Based on the amplification profiles of the genotypes by the remaining pr...

the genetic diversity of 89 flue-cured tobacco varieties was examined using 12 issr primers. these cultivarswere evaluated at the guilan tobacco research center, rasht, iran, using a 7×7 simple lattice design with two replications, and 12 morphological traits. the total number of pcr amplified products was 143 bands ranging from 450 to 3000 bp, of which 108 bands (74.28%) were polymorphic. prim...
Propagation through tissue culture by using orchid seed as explants will produce a lot of plants. This study aims to measure the genetic character plantlets that were regenerated from seeds which have been resulted in vitro culture. The original plants produced was determined Random Amplified Polymorphic DNA (RAPD) molecular markers. results showed primers used RAPD analysis polymorphic band pa...
the population genetic structure of the persian sturgeon (acipenser persicus) in the sefidrud and gorganrud river watersheds was analyzed based on the characterization of microsatellite markers. one hundred fin clip samples of persian sturgeon from the two regions were collected. four microsatellite loci (ls68, spl168, spl173, and afu68) were analyzed for molecular characterization, resulting i...
