تنوع ژنتیکی در 22 مورفوتیپ گندم دیپلوئید t. urartu (ژنوم aa) با استفاده از صفات ریخت شناسی و نشانگرهای rapd بررسی گردید. ارزیابی ها براساس 17 صفت ریخت شناسی و زراعی انجام شد و پارامترهای آماری صفات زراعی شامل پراکندگی و تنوع محاسبه گردید. نتایج نشان دهنده تنوع ژنتیکی بالایی برای اکثر صفات مورد مطالعه بود. در مطالعات زراعی و ریخت شناسی تشابه موجود بین مورفوتیپ ها با استفاده از ضریب فاصله اقلیدسی...
Background and Aim: Liver disease during pregnancy can complicate up to 3% of all pregnancies. Subtle presentation, overlap makes the differential diagnosis a real time challenge. There is insufficient prospective data on spectrum outcome liver in pregnant population from India. Methods: This retrospective study was planned evaluate various diseases females presenting Gastroenterology departmen...
ساختار ژنتیکی 31 جمعیت بابونه جمعآوری شده از مناطق مختلف ایران، با استفاده از پانزده ترکیب مختلف از نشانگرهای aflp که تعداد 237 نوار چندشکل تولید کردند، مورد ارزیابی قرار گرفت. از بین نشانگرهای مورد استفاده، نشانگر e41-m62 با 25 بیشترین و نشانگر e39-m93 با 11 نوار کمترین تعداد نوار چندشکل را ایجاد نمودند. علاوه بر آن، نشانگر e35-m93 و e40-m62 به ترتیب با تولید 15 و 17 نوار 100 درصد چندشکل بودند...
In this study, we evaluated three PCR-based methods for the molecular typing of nonpathogenic Fusarium oxysporum isolates: random amplified polymorphic DNA (RAPD), polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) and amplified fragment length polymorphism (AFLP). The analyses were performed using 64 isolates of F. oxysporum collected from cotton-producing areas in E...
Amplified fragment length polymorphism (AFLP) markers allow a rapid assessment of the level of genetic variation that would be difficult to evaluate using a limited number of morphological markers. AFLP was used to assess the level of genetic variation among 16 different Phalaenopsis species and hybrids. Ten AFLP primer combinations were used for genetic analysis of these Phalaenopsis and 95% o...
Bacteria of the genus Klebsiella are opportunistic pathogens responsible for an increasing number of multiresistant infections in hospitals. The two clinically and epidemiologically most important species, Klebsiella pneumoniae and K. oxytoca, have recently been shown to be subdivided into three and two phylogenetic groups, respectively. The aim of this study was an in depth evaluation of the a...

The Neolithic introduction of domestic cattle into Europe was followed by differential adaptation, selection, migration and genetic isolation, leading ultimately to the emergence of specialized breeds. We have studied the differentiation of European cattle by amplified fragment length polymorphism (AFLP) fingerprinting. Combining AFLP data sets from two laboratories yielded 81 biallelic polymor...
The simplified AFLP method was developed and evaluated for identification and genetic diversity studies of wheat cultivars. Selective primers exploited in AFLP assay based on a single cutting enzyme PstI ((PstI)AFLP) generated total of 111 robust fragments, including 67 (60%) monomorphic and 12 (11%) cultivar-specific markers. Average similarity between 15 cultivars was 0.650, and varied from 0...
The Amplified fragment Length Polymorphism (AFLP) is one of the cost-effective and useful fingerprinting techniques to study non-model species. One crucial AFLP step in the AFLP procedure is the choice of restriction enzymes and selective bases providing good-quality AFLP profiles. Here, we present a user-friendly program (ISIF) that allows carrying out in silico AFLPs on species for which whol...
