for many years, assessment of olive oil quality and itsauthenticity confimation has been of great importanceto guarantee olive oil safety in compliance with legislations. these include the investigation of olive oil purityand quality by analyzing several parameters such as fattyacid composition, sterols, phenolic compounds, triacylglycerol and etc, through performing conventional andadvanced hy...

background and objectives: the escherichia coli strains are greatly important in nosocomial and community acquired infections. the aim of this study was to determine the transmission of bacterial infections using genetic analysis. materials and methods: two hundred and thirty escherichia coli strains, isolated from different clinical samples, were characterized by enterobacterial repetitive int...

forty monoconidial isolates of magnaporthe grisea were examined, for an identification of vegetative compatibility group and a characterization of genetic diversity, using rep-pcr genomic fingerprinting. the isolates were collected from weeds digitaria sanguinalis (crabgrass), setaria italica (foxtail millet), echinochloa crus-galli (barnyard millet), and some other unknown ones during 2003 - 2...

evaluation of genetic diversity is a considerable approach to screen within indigenous rhizobial population for compatible, highly effective strains, which can be further utilized as rhizobial inoculums. genetic diversity of rhizobium isolates from three clover species grown in soil samples of seven different geographical regions in iran was investigated by repetitive extra genomic palindromic ...

a reliable dna extraction method for use on extra virgin olive oil based on a commercial kit was defined, and the possibility of using this dna for fingerprinting the original cultivar was demonstrated. the genetic traceability of single-cultivar virgin olive oil from two cultivars (carolea and frantoio) was achieved by identifying the varieties from which they were produced. this involved the ...

objective(s) pseudomonas aeruginosa is the most important cause of chronic lung infections and death in patients with cystic fibrosis. determining the distribution of specific strains within patient populations is important in order to examine the epidemiology of the disease and the possibility of cross infection among patients. materials and methods forty six iranian patients with cystic fibro...

thirty five monoconidial isolates of the fungal culture collection pyricularia grisea were examined, to identify the vegetative compatibility groups and characterize the genetic diversity of isolates as through rep-pcr genomic fingerprinting. the isolates were collected from ricefields during 1997-1999. genetic diversity of p. grisea isolates was studied as based on dna fingerprinting through r...

DNA fingerprinting exhibits multilocus genotypes of individuals, detected by the use of a single multilocus probe. Consequently, population data on DNA fingerprinting do not provide a complete characterization of the genetic variation in terms of allele-frequency distributions, since neither the number of loci nor the locus affiliation of alleles is directly observable. Yet DNA fingerprinting h...

Rice as one of the most important agricultural crops has a putative potential for ensuring food security and addressing poverty in the world. In the present study, in order to provide basic information to improve rice through breeding programs, Inter Simple Sequence Repeat marker (ISSR) was used For DNA fingerprinting and finding genetic relationships among 32 different cultivars. In this study...
