inter simple sequence repeat (issr) markers were used to assess the genetic diversity among 23 outcross and self pollinated populations of fennel collected from different geographical regions of iran and some european countries. the experiment was carried out to determine the effect of self-pollination on morphological traits and genetic diversity in the next generation. fifteen primers produce...
molecular characterization of 19 jatropha accessions that included 15 accessions of j.curcas and 4 different species was carried out using 3 different markers systems. highest polymorphism (96.67%) was recorded by rapd followed by damd (91.02%) and issr (90%). polymorphism information content (pic) was higher for damd (0.873) and almost equal for rapd (0.863) and issr (0.862) markers, whereas r...
having knowledge about genetic relationships among accessions is necessary for developing breeding strategies to produce improved cultivars. in present study, genetic diversity and inter-relationship among 29 genotypes of citrus were comparatively analyzed using morphological and rapd markers. significant variability was observed among citrus genotypes for 61 quantitative and qualitative morpho...
the flowering and fructification period of the chilean strawberry (fragaria chiloensis (l.) duch.) is restricted to approximately 2 mo, which seriously limits the commercial development of the species. the objective of the current investigation was to identify inter simple sequence repeat (issr) polymorphisms associated with flowering duration in accessions of f. chiloensis. the flowering durat...
iran is a part of the secondary centre of origin of melons, and therefore, there is a wealth of genetic variation of these species in this country. the amplified fragment length polymorphism (aflp) marker was applied to investigate the genetic variations among five major iranian melon cultigens (cucumis melo) and ‘ananasi’ as a general well-known cultivar. ten primer pairs were used on 90 indiv...
context triple negative breast cancer (tnbc) is a heterogeneous group of diseases that is negative for esterogen receptor (er) progesteron receptor (pr) and human epidermal growth factor receptor 2 (her2). this type of breast cancer is typically high-grade carcinomas, although low-grade tumors occur. the aim of this review is to focus on molecular classification and features, prognostic markers...
genetic markers are one of the advances which have occured in the genomics era. among genetic markers, molecular markers mainly because of their abundance, are the most widely used them. development of molecular markers has greatly altered genetics and plant breeding. genetic markers indicate the genetic differences between different organs or species. some studies which were conducted during t...
the aim of the present study was to investigate the frequency and the type of discourse markers used in the argumentative and expository writings of iranian efl learners and the differences between these text features in the two essay genres. the study also aimed at examining the influence of the use of discourse markers on the participants’ writing quality. to this end the discourse markers us...
study of genetic relationships is a prerequisite for plant breeding activities as well as for conservation of genetic resources. in the present study, genetic diversity among and within 15 iranian native ajowan(carum copticum l.) populations were determined using inter simple sequence repeat (issr) markers. twelve selected primers produced 153 discernible bands, with 93 (60.78%) being polymorph...
Neuroblastoma, one of the common malignant childhood tumors, arises from neuroblast cells derived from theneural crest and destined for the adrenal medulla and the sympathetic nervous system and shows remarkable biologicalheterogeneity, resulting in favorable or unfavorable outcomes. Some tumors make rapid progress with a fataloutcome. In other instances, the tumors regress spontaneously in inf...
