The amplified fragment length polymorphism (AFLP) technique is being increasingly used in phylogenetic studies, especially in groups of rapidly radiating taxa. One of the key issues in the phylogenetic suitability of this technique is whether the DNA fragments generated via the AFLP method are homologous within and among the taxa being studied. We used a bioinformatics approach to assess homolo...
Several studies have reported a positive association between caesarean section for expeditious pregnancy termination and perinatal outcomes in acute fatty liver of pregnancy (AFLP); however, the risks remain unclear and independent studies have reported conflicting findings. In this meta-analysis, we aimed to confirm the relationship between caesarean section and perinatal outcomes in AFLP. The...
در این مطالعه به منظور شناسایی نشانگرهای ملکولی مرتبط با 22 صفت آگرومورفولوژیک در 48 توده مختلف آفتابگردان آجیلی بر اساس مدل های glm و mlm، از 12 آغازگر مبتنی بر رتروترنسپوزن (7 آغازگر irap و 5 آغازگر remap) استفاده شد. تجزیه کلاستر با روش neighbor joining، توده های آفتابگردان مورد مطالعه را به 3 گروه اصلی تقسیم بندی کرد. مطالعه ساختار جمعیت به عنوان پیشنیازی برای انجام تجزیه ارتباط به روش بیزی...
در این تحقیق، یک جمعیت f2 متشکل از 188 بوته حاصل از تلاقی بین دو رقم خالص بینام و کادوس در سال 1387 در مزرعه تحقیقاتی دانشکده علوم کشاورزی دانشگاه گیلان کشت و صفات مرتبط با عملکرد دانه اندازه گیری شد. dna ژنومی والدین و افراد جمعیت f2 به روش ctab استخراج و سپس با استفاده از 85 نشانگر ssr و 20 نشانگر aflp مورد بررسی قرار گرفت. نتایج نشان داد که 37 نشانگر ssr و 35 نشانگر aflp چندشکلی خوبی در بین ...
BACKGROUND Neonectria ditissima is one of the most important fungal pathogens of apple trees, where it causes fruit tree canker. Information about the amount and partitioning of genetic variation of this fungus could be helpful for improving orchard management strategies and for breeding apple cultivars with high levels of genetically determined resistance. In this study single-spore Neonectria...
Three different types of molecular markers, RAPD, SSR and fluorescence-based AFLP, were evaluated and compared for their ability to identify oilseed rape cultivars. The direct comparison of RAPD, SSR and AFLP approaches in cultivar identification showed that the AFLP methodology detected polymorphisms more efficiently than either RAPD or SSR methods. For the characterisation of six oilseed rape...
For epidemiological tracing of the thermotolerant Campylobacter species C. jejuni and C. coli, reliable and highly discriminatory typing techniques are necessary. In this study the genotyping techniques of flagellin typing (flaA typing), pulsed-field gel electrophoresis (PFGE), automated ribotyping, and amplified fragment length polymorphism (AFLP) fingerprinting were compared. The following as...
To understand Staphylococcus aureus nasal carriage and its relationship with subsequent disease, insight into the natural (nonclinical) bacterial population structure is essential. This study investigated whether the distributions of S. aureus genotypes that cause colonization differ by geographic locales. High-throughput amplified fragment length polymorphism (AFLP) analysis was performed on n...
We estimated the genetic distances among 10 spring wheat genotypes based on pedigree data, morphological traits and AFLP markers, used individually and combined with morphological traits, to find the best predictors of general- and specific-combining abilities among parental genotypes. Ten wheat parents were crossed in a diallel form, disregarding reciprocal hybrids, totaling 45 combinations. T...
The genetic variation and population structure of three populations of Anopheles darlingi from Colombia were studied using random amplified polymorphic markers (RAPDs) and amplified fragment length polymorphism markers (AFLPs). Six RAPD primers produced 46 polymorphic fragments, while two AFLP primer combinations produced 197 polymorphic fragments from 71 DNA samples. Both of the evaluated gene...
