Wild olive (O. europaea ssp cuspidata) plants grow in various regions of Iran and are expected to have considerable genetic diversity due to adaptation to the various environmental conditions. We examined the genetic diversity of four populations of wild olive growing in Hormozgan Province located in southern Iran by using 30 RAPDs and 10 ISSR markers. The mean value of polymorphism for RA...

Five Fusarium graminearum and 12 F. culmorum isolates, primarily pathogenic species of Fusarium head blight, were obtained from naturally infected wheat from various agro-ecological regions of Turkey. Genotyping of the isolates was carried out using random-amplified polymorphic DNA (RAPD). Sixty-five 10-mer oligonucleotide primers were used to amplify the RAPD markers. Among them, 50 primers pr...

The diversity of wild mushrooms was investigated from two protected forest areas in India and 231 mushroom specimens were morphologically identified. Among them, 76 isolates were screened for their antimicrobial potential against seven bacterial and fungal pathogens. Out of 76 isolates, 45 isolates which displayed significant antimicrobial activities were identified using ITS rRNA gene amplific...

As a first step to mapping quantitative trait loci for mating system differences, a genetic linkage map was generated from an interspecific backcross between Mimulus guttatus and Mimulus platycalyx. The linkage map consists of 99 RAPD and two isozyme markers. Eighty-one of these markers were mapped to 15 linkage groups, spanning 1437 contiguous centiMorgans, and covering 58% of the estimated ge...

Two RAPD primers and 15 protein biochemical markers were examined to assess the zygosity (hetero/homozygocity) and per cent polymorphisms in monogamous (IM: IF) and triogamous (1M:2F) breeding groups of outbred Mongolian gerbils (Meriones unguiculatus). No polymorphism and heterozygosity were found in RAPD as well as biochemical markers in monogamous groups, whereas both primers in RAPD (%P=55%...

background: keeping in view the havoc situation of dengue fever in pakistan, the current study was designed to demon­strate the genetic variations, gene flow and rate of migration from lahore and faisalabad. methods: the larvae were collected from both natural and artificial breeding places from each collection site. the adult mosquitoes were collected by means of sweep net and battery-operated...

Using the random amplified polymorphic DNA (RAPD) technique and exploiting the unique genetics of Tetrahymena thermophila, we have identified and characterized 40 DNA polymorphisms occurring between two inbred strains (B and C3) of this ciliated protozoan. These RAPD markers permit the PCR amplification of a DNA species using template DNA from SB1969 (B strain) but fail to do so using DNA from ...

Genetic markers facilitate the study of inheritance and the cloning of genes by genetic approaches. Molecular markers detect differences in DNA sequence, and are thus less ambiguous than phenotypic markers, which require gene expression. We have demonstrated a molecular approach to the mapping of mutant genes using RAPD markers and pooling of individuals based on phenotype. To map genes by phen...

Random amplified polymorphic DNA (RAPD) markers have been used for many types of genetic analyses, including genome mapping, genotype fingerprinting, phylogeny reconstruction, and measuring genetic similarities. They suffer from one potential limitation, however, because the PCR that is used to produce informative amplification products often produces artifactual products as well. Optimization ...

BACKGROUND Root-knot nematodes are known to cause significant damage to eggplants. New approaches by green silver nanoparticles (GSN) are used to control plant-parasitic nematode to avoid chemical nematicide hazards. OBJECTIVES Analyses of the incorporation of different concentrations of nanoparticles on two different algae (Ulva lactuca and Turbinaria turbinata) were carried out. Furethermor...
