to evaluate allelic diversity at loci encoding low molecular weight glutenin subunits (lmw-gs) among 62 genotypes of bread wheat, nine specific primer pairs for glu-a3, glu-b3, glu-d3 loci were employed. pcr products were separated on 2% agarose gels. two pairs of specific primers, at amplified glu-a3 locus, 8 alleles were detected the c allele of which was the most abundant with a frequency of...

expressed sequence tags simple sequence repeats (est-ssrs) are important sources for investigation ofgenetic diversity and molecular marker development. similar to genomic ssrs, the est-ssrs are usefulmarkers for many applications in genetics and plant breeding such as genetic diversity analysis, molecularmapping and cross-transferability across related species and genera. in spite of low polym...

Precise investigation of genetic diversity by means of novel molecular tools has made it possible to identify the superior genotypes among various male and female pistachio populations. Cytogenetic studies have shed light on the possible presence of distinct sex chromosomes in male and female genotypes. In this study, 22 start codon targeted (SCoT) primers were used to investigate the genetic d...

genetic diversity is a key component of ecosystems. the aim of the present study was to evaluate the genetic diversity of iranian native honeybee colonies (apis mellifera meda l.) located in the northern region. colonies from 24 locations have been analyzed using microsatellite markers. samples were collected from caspian sea southern area (north of iran). six microsatellite markers (a28, a29, ...

die-back disease caused by paecilomyces variotti is one of the most destructive diseases of pistachio in iran. in this study, genetic diversity of paecilomyces variotti isolates was investigated with ssr marker, using six primers pairs. sampling was done from pistachio gardens in different geographical zones of kerman province during summer 2013. various fungal isolates were isolated from infec...

sardari is one of the most important landraces of common wheat (triticum aestivum l.) that is mainly cultivated in drylands and mountainous area of iran. moreover, it shows a high level of genetic diversity. in the present research a total of 73 sardari wheat ecotypes were evaluated for drought tolerance. genetic diversity was analyzed using amplified fragment length polymorphism (aflp) marker ...

study of genetic relationships is a prerequisite for plant breeding activities as well as for conservation of genetic resources. since the hybrid canola have more yield than inbred lines, determine the genetic diversity of this have particular importance. in the present study, genetic diversity among 36 genotype of brassica sp. were determined using inter simple sequence repeat (issr) markers. ...

in this study, the genetic diversity among paecilomyces variotti isolaes was investigated. sampling was performed from pistachio garden in seven geographical region of kerman province during 2011-2012. seventy isolates were identified as p. variotii species using morphological criteria. the genetic diversity among 20 selected isolates was assayed by variation at ssr marker bands using 12 pair p...

breeding for resistance is one of the main approaches to control diseases. in this approach, there is a necessary for existence a sufficient genetic variability of resistance genes. accordingly, assessing the genetic variability in the available germplasm is needed to manage genetic resources. molecular markers are effective tools to investigate genetic diversity for resistance to pathogens. nb...
