بررسی تنوع ژنتیکی ژنوتیپهای بومی پیاز ایرانی در مقایسه با انواع خارجی چکیده: برنامه های اصلاحی گیاهان بر اساس تنوع و انتخاب صفات برتر کمی و کیفی صورت می گیرد. لذا، ارزیابی تنوع ژنتیکی، اولین مرحله در برنامه های اصلاحی است. در این راستا، استفاده از روش های جدید مطالعهی تنوع ژنتیکی ضروری به نظر می رسد. در این بررسی تعیین تنوع ژنتیکی سیزده ژنوتیپ پیاز ایرانی در مقایسه با دو ژنوتیپ خارجی با است...
in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
beet western yellows virus (bwyv), a species of the genus polerovirus in the family luteoviridae, is an agriculturally important virus infecting over 150 plant species in 23 dicotyledonous families worldwide. a survey of bwyv in canola fields in golestan and tehran provinces of iran using indirect triple antibody sandwich enzyme-linked immunosorbent assay (tas-elisa) indicated 8.3 % infection. ...
genetic diversity of five improved varieties (kaysari, kadi, ranger, mesmir, sea-river) and seven iranian landraces (gharayonje, amozeynadin, rahnani, tazekand, shazand, hamedani, yazdi) of alfalfa were assessed using esterase (est), peroxidase (pox), glutamate oxaloacetate transaminase (got) and malate dehydrogerase (mdh). got and mdh were monomorphic, whereas est and pox showed polymorphic ba...
Community structure has been widely identified as a feature of many real-world networks. It has been shown that the antigenic diversity of a pathogen population can be significantly affected by the contact network of its hosts; however, the effects of community structure have not yet been explored. Here, we examine the congruence between patterns of antigenic diversity in pathogen populations i...
Chrysanthemum (Chrysanthemum morifolium) is one of the most important ornamental plants which plays a significant role in the development of gardening industry in the world. The knowledge of genetic diversity is one of the prerequisite criteria for Chrysanthemum breeding with important economic goals. Molecular markers have a significant share in elucidation of inter and intra species genetic d...
abstract seedless barberry (berberis vulgaris l. var. asperma) is one of the few crops that is cultured only in iran and southern parts of khorasan provinces. the origin of this variety is unknown and there has not been any study aiming to identify phylogenic relationships of this plant with other species existing in iran. in this study, aflp markers based on four primer combinations (ecori/tru...
Annual medics are used for hey production, soil protection, biological fixation of N2 and green manure. In the present study, the inter and intra specific genetic diversity and relatedness of 4 diploid and two tetraploid (M. rugosa and M. scutellata) annual medics were evaluated using microsatellite markers. PCR analysis was performed on genomic DNA from individual plant and PCR products were d...

Hot pepper (Capsicum spp.) is an economically important spice widely cultivated and consumed in Ethiopia. In spite of its wide importance, there is no information available on the molecular genetic diversity of this crop. Cultivars characterization is an important link between the conservation and utilization of plant genetic resources in various breeding programs. Using five ISSR prim...
