Hypericum L. species are generally known locally in Iran with the names “Hofariqun” which Ebn Sina (or Bo Ali Sina) called it. Plants of genus have traditionally been used as medicinal plants various parts world. perforatum is source to one most manufactured and herbal preparations recent years, especially a mild antidepressant. Therefore, due importance these plant species, we performed molecu...
The RAPD-PCR technique was applied to identify genetic markers able to distinguish between four canid species: the arctic fox (Alopex lagopus), red fox (Vulpes vulpes), Chinese raccoon dog (Nyctereutes procyonoides procyonoides) and six breeds of the domestic dog (Canis familiaris). A total of 29 ten-nucleotide arbitrary primers were screened for their potential use in the differentiation of th...
To exploit the polymorphism of repeat numbers in short tandem repeat (STR) sequences (microsatellites) as molecular markers, STRs must be isolated and PCR primers must be developed in flanking sequences. In species with large genomes such as Allium cepa L. (onion and shallot), an efficient selection procedure for genomic fragments containing STRs is a crucial step. Here we describe a nonradioac...
Out of fifty-two Iranian nonaflatoxigenic strains of Aspergillus flavus, which were collected from various substrates (soil and kernel) and sources (peanut, corn and pistachio), fifteen representatives were selected according to their different geographical origins (six provinces: Guilan and Golestan, Ardebil, Fars, Kerman and Semnan) and vegetative compatibility groups (VCGs, IR1 to IR15) for ...
in this study, genetic diversity of 30 accessions of the fennel from different cities of iran and other asian and european countries were assessed by using 20 selective aflp primers. totally, from 1127 observed bands, 250 bands were polymorph. e11-m20 primer with 20 bands, also e46-m35 and etg-m20 primers with 8 bands indicated the maximum and minimum numbers of polymorphism, respectively. acco...
ISSR markers were used to determine the genetic variation and sex determination of the three life-stages of 41 samples of Gracilaria corticata from two regions of the Persian Gulf and Oman Sea namely Bostaneh and Lipar. The specimens were cultured in PES media to observe the different life stages. DNA was extracted by modified CTAB method. After screening of 20 ISSR primers, four primers were s...
background: dicrocoelium dendriticum, a liver trematode of herbivores, and man is very prevalent among ruminants of iran, resulting in causing significant economic losses. recently its phenotype polymorphism has been found in iran, a phenomenon that may affect the protein profile of the parasite. objectives: the aim of this study was to determine the somatic protein profiles of d.dendriticum in...
The genetic diversity of 19 bitter vetch landraces (Vicia ervilia L.) from four provinces (East Azerbaijan, West Azerbaijan, Ardabil and Zanjan) of Iran was evaluated using 18 pairs of SSR primers. The extracted genomic DNA was amplified with eight pair primers and PCR products were separated on DNA sequencing gels. In this research, eight pair of SSR primers detected a total of 27 alleles...
Twenty-two G. glabra populations were used to study the genetic diversity of ISSR molecular markers. 12 primers were used to amplification of genomic DNA fragments of G. glabra populations. High genetic diversity based on ISSR markers was observed among individuals. A total of 130 bands were formed and 105 bands were polymorphic. The mean polymorphism percentage among studied populations was 80...
Genetic diversity among ginger genotypes collected from different parts of the country was studied using molecular markers (30 RAPD and 55 SSR). Compared to primers SSR were efficient in distinguishing genotypes. A total 86 23 polymorphic bands observed with primers, respectively. Percentage polymorphism between 97.40 % 56.54 %. Grouping by combined data indicated that irrespective their place ...
